CALIFORNIA PROPOSITION
65 WARNING:

This product and
related accessories contain
chemicals known to the State of
California to cause cancer, birth
defects or other reproductive
harm.

Pumps Not Operating or
in Storage:

Pumps with carbon ceramic seals
must have impellers manually
rotated (6 revolutions) after
setting non-op er a tion al for 3

2

months or longer and prior to
electrical start-up.

Pumps with tungsten carbide seals
must have impellers manually
rotated (6 revolutions) after
setting non-op er a tion al for
3 weeks or longer and prior to
electrical start-up.

Pump:

The submersible pumps are
supplied for three phase only and
for 460 and 575 volts. Power
cable is supplied with ground. Be
sure ground wire is con nect ed to a
water pipe or ground stake.

Power Cords:

The power cord and heat sensor
seal failure cord are potted into
the con nec tion box cap. The cords
must not be spliced.

NOTE: Each cable has a green
lead. This is the ground wire
and must be grounded properly
per NEC and/or local codes.
Cords should be in spect ed for
abnormal wear and replaced
ac cord ing ly.

Overload Heaters:

If the Hydromatic electrical
panel is not used, start ers with
3 leg overload relay must be
supplied on 3 phase pumps.
Each leg is to have an iden ti cal
heater sized in accordance with
the nameplate amps on the motor
hous ing. The amp draw on these
sub mers ible motors is slightly
higher than a cor re sponding
horsepower sur face motor, so
heat ers must be sized by the
nameplate rating. To adequately
protect these windings with the
appropriate heaters, consult the
factory.

Seal Failure Probes:

All hazardous location
submersible pumps have two
factory installed mois ture
detectors (seal failure probes).
They are in a normally open series
cir cuit, in the seal chamber. Un der
normal operating conditions, the

circuit remains open. If the lower
seal leaks and moisture enters this
cham ber, the moisture would settle
to the bottom of the chamber and
will com plete the circuit between
the mois ture detectors.

This circuit must be connected
to a sensing unit and signaling
device. This is supplied in a
Hydromatic built control panel.

NOTE: Failure to install such a
device negates all war ran ties by
Hydromatic.

Seal Failure:

An electrode probe is installed in
the seal chamber so if any water
enters the chamber through the
first seal the electrode will be
energized and a sig nal will be
transmitted to the sens ing unit at
ground surface causing a red light
to turn on. The electrode probe
is installed in all units but the
sensing unit is supplied at extra
cost and must be ordered.

In operation the seal failure unit
in di cates only that there is some
water in the seal chamber. The
pump will con tin ue to operate
without damage but the seal
should be checked im me di ate ly
after failure is indicated.

The sensing unit is recommended
on all installations as good
insurance against motor failure.

Heat Sensors —

Standard Equipment:

All motors have heat sensor units
em bed ded in the motor winding
to detect excessive heat. The
sensors automatically reset when
mo tor cools to safe tem per a ture.

The sensors are connected in
series with the motor starter coil
so that the starter is tripped if
the heat sensor opens. The motor
starter is equipped with overload
heaters so all normal over loads
are protected by the starter.

Sump Level Control:

Sump level is controlled by
Hydromatic float switch con trols.

The float is held in position in
the sump by a weight at tached to
the power cord above the float.
The cord supports the float and
is adjusted for height from the
sur face.

Duplex systems use three
controls: one set at turn-off, one
set at turn-on for one pump, and
one set for turn-on for two pumps.
Pumps alternate op er a tion on each
successive cycle.

Two pumps operate together only
if sump level rises to the third
or over ride control. The override
control also brings on the second
pump in case of failure of the first
pump. The extra float is for alarm.

Triplex systems use four controls:
one set at turn-off, one set at
turn-on for one pump, one set
at turn-on for two pumps, and
one set at turn-on for three
pumps. Pumps alternate each
successive cycle.

Three pumps operate together
only if sump level rises to the
fourth control (second override).
This control also brings on
the third pump in case of failure
of either or both of the first
two pumps.

Alarm Controls:

The alarm level is usually set
above the override level so the
alarm will signal only if the
override level is ex ceed ed.
However, some engineers prefer
to have the alarm level set be low
the override level as it is pos si ble
for one pump to fail and the other
pump to operate on the override
level with the sump level never
reach ing the alarm level. This is
par tic u lar ly true in cases of low
inflow ca pac i ty.

Electrical Control Panel:

Hydromatic electrical equip ment
is installed in a weatherproof
NEMA 3R enclosure. The
electrical equip ment includes
a main circuit breaker for each
pump, a magnetic starter with
overload protection for each

pump, an H-O-A switch and run
light for each pump, an electric
alternator and a transformer to
provide appropriate control for
control and circuit and alarms.

Installation
Instructions

Installing Pump in Sump:

Before installing pump in sump,
lay it on side and turn impeller
manually. Impeller may be
slightly stuck due to factory test
water, so it must be broken loose
with small bar or screwdriver
in edge of vanes. After breaking
loose, the impeller should
turn freely.

Clean all trash and sticks from
sump and connect pump to piping.

A check valve must be installed
on each pump. A gate or plug
valve in each pump discharge
line is also recommended. This
valve should be installed on the
discharge side of the check valve
so if it is necessary to service the
check valve, the line pressure can
be shut off.

NEMA IV Junction Box:
(Optional)

This must be used with 60 and
above horsepower pumps and
with all systems if the electrical
control panel is to be set remote
from the pumps. The Hydromatic
NEMA 4 junction box is provided
with com pres sion connectors
for sealing all wires. No sealing
compound is needed to make
connections wa ter proof.

Wiring diagrams are provided
with the panel for making
connections. The size wire to use
from panel to sump depends on
motor size and distance in feet.

Be sure each wire is checked
so that a wrong connection will
not be made. An ohmmeter or
Megger can be used to check
wire continuity.

Installing Float Switch Controls:

The controls are supported by a
mounting bracket that is attached
to sump wall, cover, or to the
NEMA 4 junction box. Cord
snubbers are used to hold the cord
in place. Control level can be
changed at any time by loosening
the snubber and readjusting
cord height.

In either duplex or triplex
systems, the bottom of the lower
or turn-off control is set just above
the top of volute, so that the volute
will always be submerged during
the pumping cycle. The second,
or turn-on control, is set about
24 inches above the lower turn-off
control.

More distance between turn-on
and turn-off controls can be used,
but sewage may become septic,
and excessive solids may collect
for the pump to handle. A frequent
pumping cycle is recommended
for best operation.

In a duplex system the third or
override control is usually set
about 6 inches above the one pump
turn-on control.

In a triplex system the third or
override control is usually set
24 inches above the one pump
turn-on control, and the fourth
or second override control is
24 inches higher.

If an alarm system is used, this
control is usually set about 6
inches above the override control.

Making Electrical Connections:

All electrical wiring must be in
ac cor dance with local codes, and
only competent electricians should
make the in stal la tions. Complete
wiring diagrams are glued to the
inside cover of the panel. All wires
should be checked for grounds
with an ohmmeter or Megger after
the con nections are made. This is

important, as one grounded wire
can cause considerable trouble.

will exist. One leg can be
somewhat higher (5 to 10%)
without causing trouble.
For excessive amp draw on
one leg, the power company
should be consulted.

is required.

Generally, these pumps give
very reliable service, and can
be expected to operate for many
years on normal sewage pumping
without failure.

Pump
Operations

Starting System:

1. Turn H-O-A switch to
Off position and then turn on
main circuit breakers.

2. Open all discharge valves and
allow water to rise in sump.

3. Turn H-O-A switch to Hand
posi tion on one pump and
notice oper ation. If pump is
noisy and vibrates, rotation
is wrong. To change rotation,
interchange any two line
leads to motor 3ø only. Do not

interchange main incoming
lines. If duplex system, check

second pump in same manner.

4. Now set both H-O-A switches
to Auto position and allow
water to rise in sump until
one pump starts. Allow pump
to operate until level drops to
turn-off point.

5. Allow sump level to rise to
start other pump. Notice run
lights on panel. Pumps should
alternate on each successive
cycle of op er a tion.

6. Turn both H-O-A switches
to Off position and allow
sump to fill to the override
control level.

7. Turn both switches to Auto
position and both pumps
should start and operate
together until level drops to
turn-off point.

8. Repeat this operation
cycle several times before
leaving job.

9. Check voltage when pumps
are operating and check the
amp draw of each pump.
Check amps on each wire,
as sometimes a high leg

Pump
Maintenance

Field Service on Hydromatic
Hazardous Location Pumps:

If a Hydromatic hazardous location
pump is used in a hazardous
location, or if the pump is still
in war ran ty, the pump must be
returned to the factory for service
or repaired at an authorized
Factory Mutual Hydromatic
service center. Charges will not
be allowed if in war ran ty pump is
not taken to an authorized Factory
Mutual Hydromatic service center.
This will ensure the integrity of
the hazardous location rating of
the pump and com ply with our
warranty re quire ments.

Disconnecting Pump Cords:

If a Hydromatic hazardous location
pump is to be removed from its
loca tion, the pump cords may be
disconnected at control panel (on
sump mounted con trol panels) and
cord as sem bly taken with pump.

CAUTION: If cord openings
from sump to con trol panel are
open, gas es from sump could
enter panel and an explosive
condition could ex ist.

Replacing Cords:

The power cord and heat sensor ­seal failure cord is potted into the
con nec tion box cap, forming the
cord and cap assembly.

If cords require replacement due to
damage or cords being too short,
cord and cap assembly must be
replaced as a complete assembly
avail able from factory.

Check pump for proper rotation
before re turn ing to normal service.

Motor:

As the motors are oil filled, no
lubrication or other maintenance

Field Service on Motor:

All submersible motors out
of warranty can be serviced in
the field by any reliable motor
service shop. Any pump in
warranty must be returned to the
factory for service or repaired
at an authorized Hydromatic
service center. Charges will not
be allowed if in warranty pump is
not taken to an authorized
Hydromatic

When field service is performed
on a pump, these instructions
should be carefully followed.

Replacing Stator:

1. If stator only is damaged,
it may not be necessary to
completely dismantle pump
as stator and housing can be
lifted from pump without
disturbing seals or bearings.

2. Drain all oil from upper
housing, remove drain plug in
bottom of stator housing and
remove plug in top of housing
to allow air to enter.

3. After chamber is drained,
remove hold-down bolts
and lift off. Use care in
lifting as the seal failure
connecting wire must be
dis con nect ed before housing
is com plete ly removed.

4. Set assembly on bench and
remove connection box.
When box is lifted off,
connection wires to motor will
be exposed. These wires will
probably be burned, but each
wire is tagged with a metal
marker giving wire number.
Cut the wires.

If the leads to the connection

box are burned, a complete
new con nec tion box with new
wire must be used. The wires

service center.

are potted in with sealing
compound and a new unit
must be obtained from
the factory.

5. The stator is held in the
housing with a bolted-in
retaining ring and prevented
from rotating by a key.

6. Remove the retaining ring and
socket head cap screw.

7. After ring is removed, turn
housing upright and bump on
hard wood blocks. This should
jar the stator loose and allow
it to drop out.

8. Thoroughly clean housing
before replacing new stator.
Replace stator and make
all wire con nec tions to
the connection box before
replacing housing on pump.
This is important as leads
must be tucked behind the
windings by using hands up
through rotor core.

Do not tape leads as oil will
de te ri o rate the tape and cause
damage to stator and bearings.

9. Check top bearing. If clean
and does not turn rough,
bearings can be reused and it
is not necessary to completely
dismantle pump to change
bearings. If bearings are
damaged with dirt or heat,
they must be re placed.

10. Replace stator housing onto
seal chamber and bolt in place.

Be sure seal failure wire is
connected before housing is
assembled. Be sure back-off

screws have been loosened
so that parts can come metal
to metal. Be sure O-ring seal
has been replaced. If O-ring
is nicked or cut, replace with
new ones. This applies to all
O-rings used in assembly.

11. After all leads are reconnected
in the connection box, make
a high voltage ground test
on each wire. The only wire
that should show ground is
the green power lead and the

ground lead in the auxiliary
control cable.

12. For safety, complete pump
should be air checked under
water for leaks. Lay pump
on side for this oil filling
with oil fill hole upright.
Do not completely fill; leave
oil about 1 inch below plug
hole. Use only Hydromatic
submersible oil in this
chamber. Replace plug; use
Permatex on threads. Install
air valve in top plug opening
of motor housing and charge
housing with about 10 psi
of air. Be sure air is dry.
Do not use air line where
water may be trapped in
the line. Submerge complete
unit under water and check
for leaks.

13. Refill motor chamber with
oil. Use Hydromatic special
submers ible oil. Fill chamber
until oil covers top of the
windings. Leave air space in
the top for expansion. Use
Permatex on plug threads.

Replacing Seals and Bearings:

1. Drain all oil from motor
chamber and seal chamber
as described.

2. Remove motor housing as
described.

3. Remove bolts that hold seal
chamber to pump housing.
Use back-off screws to break
loose. With hardwood block,
tape end of impeller to loosen
from shaft. When free, remove
impeller from shaft.

4. Lift rotating assembly from
pump case and place on bench.

5. Impeller Removal: Hold rotor

and remove bolt and washer
from impeller end of shaft,
then thread bolt back into
shaft. The impeller is keyed
to the shaft, so by using a
screw driv er on opposite sides
behind the im pel ler, apply force
then tap on the end of the bolt
to break impeller loose from
taper shaft. Remove impeller.

6. Remove key and pry on each
side of shoulder of shaft sleeve
to remove. Seal should come
off with sleeve. If sleeve is not
free, leave in place and push off
when seal plate is removed.

7. To remove seal plate take
out socket head flat screws
and using screws in back-off
holes, pry plate loose. This
will also force seal off if not
already re moved.

8. Remove snap ring that holds
upper seal. Pull seal if it
is free. If not free, it can
be forced off when shaft
is removed.

9. Set seal housing assembly in
upright position and bump end
of shaft on hardwood block.
This will push the bearing
from the housing and will
force upper seal from shaft.

10. Use bearing puller to remove
bearings. Replace with new
bearings. Press only on
inner face of bearing when
replacing. Pressing on outer
face can damage the bearing.

IMPORTANT — Do not

use any of the old seal parts.
Replace with all new seals.

11. Thoroughly clean all castings
before replacing seals. One
grain of dirt between the seal
faces can cause failure.

12. Examine all O-Rings for nicks
before reusing.

13. Be sure key is in place in notch
of shaft sleeve to prevent
sleeve from turning.

®

14. Use Locktite

on socket head

locking screw in end of shaft.

15. Before refilling chamber with
oil, air test as described above
and refill both chambers
with oil.

16. Always check all leads with
high voltage or with Megger
for grounds before operating
the pump.

Pump
Troubleshooting

The following is a list of common
problems and their probable
causes.

Pump will not start.

1. No power to the motor.
Check for blown fuse or open
circuit breaker.

2. Selector switch may be in the
Off position.

3. Control circuit transformer
fuse may be blown.

4. Overload heater on starter
may be tripped. Push to reset.

Pump will not start and
overload heaters trip.

1. Turn off power and check
motor leads with Megger
or ohmmeter for possible
ground.

2. Check resistance of motor
windings. All 3 phases should
show the same reading.

3. If no grounds exist and
the motor windings check
OK, remove pump from sump
and check for clogged or
blocked impeller.

Pump operates with selector
switch in Hand position but will
not operate in Auto position.

1. This indicates trouble in the
level control or the alternator
relay.

2. Check control panel for
trouble.

Pump runs but will not shut off.

Pump does not deliver proper
capacity.

1. Discharge gate valve may
be partially closed or
partially clogged.

2. Check valve may be partially
clogged. Raise the level up
and down to clear.

3. Pump may be running in
wrong direction. Low speed
pumps can operate in reverse
direction without much noise
or vibration.

4. Discharge head may be too
high. Check total head with
gauge when pump is operating.
Total head is discharge gauge
pressure converted to feet
plus vertical height from
water level in sump to center
line of pressure gauge in
discharge line. Gauge should
be installed on pump side of
all valves. Multiply gauge
pressure in pounds by 2.31 to
get head in feet.

5. If pump has been in service for
some time and capacity falls
off, remove pump and check
for wear or clogged impeller.

Motor stops and then restarts
after short period but overload
heaters in starter do not trip.

1. This indicates heat sensors
in the motor are tripping due
to ex ces sive heat. Impeller
may be partially clogged,
giving a sus tained overload
but not high enough to trip
overload heater switch.

2. Motor may be operating out

CALIFORNIA PROPOSITION
65 WARNING:

This product and
related accessories contain
chemicals known to the State of
California to cause cancer, birth
defects or other reproductive
harm.

Pumps Not Operating or
in Storage:

Pumps with carbon ceramic seals
must have impellers manually
rotated (6 revolutions) after
setting non-op er a tion al for 3
months or longer and prior to
electrical start-up.

Pumps with tungsten carbide seals
must have impellers manually
rotated (6 revolutions) after
setting non-op er a tion al for
3 weeks or longer and prior to
electrical start-up.

Pump:

The submersible pumps are
supplied for three phase only and
for 230, 460 or 575 volts. Power
cable is supplied with ground. Be
sure ground wire is con nect ed to a
water pipe or ground stake.

Seal Failure:

An electrode probe is installed in
the seal chamber so if any water
enters the chamber through the
first seal the electrode will be
energized and a sig nal will be
transmitted to the sens ing unit at
ground surface causing a red light
to turn on. The electrode probe
is installed in all units but the
sensing unit is supplied at extra
cost and must be ordered.

In operation the seal failure unit
in di cates only that there is some
water in the seal chamber. The
pump will con tin ue to operate
without damage but the seal
should be checked im me di ate ly
after failure is indicated.

The sensing unit is recommended
on all installations as good
insurance against motor failure.

Heat Sensors—
Standard Equipment:

All motors have heat sensor units
em bed ded in the motor winding
to detect excessive heat. The heat
sen sors are set to trip at 105°C,
so will not op er ate unless
dangerous heat occurs. The
sensors automatically reset when
mo tor cools to safe tem per a ture.

The sensors are connected in
series with the motor starter coil
so that the starter is tripped if heat
sensor opens. The motor starter is
equipped with overload heaters so
all normal over loads are protected
by the starter.

Sump Level Control:

Sump level is controlled by
Hydromatic float switch con trols.
The float is held in position in
the sump by a weight at tached to
the power cord above the float.
The cord supports the float
and is adjusted for height from
the sur face.

Duplex systems use three
controls: one set at turn-off, one
set at turn-on for one pump, and
one set for turn-on for two pumps.
Pumps alternate op er a tion on each
successive cycle.

Two pumps operate together only
if sump level rises to the third
or over ride control. The override
control also brings on the second
pump in case of failure of the first
pump. The extra float is for alarm.

Triplex systems use four controls:
one set at turn-off, one set at
turn-on for one pump, one set
at turn-on for two pumps, and
one set at turn-on for three
pumps. Pumps alternate each
successive cycle.

Three pumps operate together
only if sump level rises to the
fourth control (second override).
This control also brings on
the third pump in case of failure
of either or both of the first
two pumps.

Alarm Controls:

The alarm level is usually set
above the override level so the
alarm will signal only if the
override level is ex ceed ed.
However, some engineers prefer
to have the alarm level set be low
the override level as it is pos si ble
for one pump to fail and the other
pump to operate on the override
level with the sump level never
reach ing the alarm level. This is
par tic u lar ly true in cases of low
inflow ca pac i ty.

Electrical Control Panel:

Hydromatic electrical equip ment
is installed in a weatherproof
NEMA 3R enclosure. The
electrical equip ment includes
a main circuit breaker for each
pump, a magnetic starter with
overload protection for each
pump, an H-O-A switch and run
light for each pump, an electric
alternator and a transformer to
provide appropriate control for
control and circuit and alarms.

Installation
Instructions

Installing Pump in Sump:

Before installing pump in sump,
lay it on side and turn impeller
manually. Impeller may be
slightly stuck due to factory test
water, so it must be broken loose
with small bar or screwdriver

in edge of vanes. After break­ing loose, the impeller should
turn freely.

Clean all trash and sticks from
sump and connect pump to piping.

A check valve must be installed
on each pump. A gate or plug
valve in each pump discharge
line is also recommended. This
valve should be installed on the
discharge side of the check valve
so if it is necessary to service the
check valve, the line pressure can
be shut off.

NEMA IV Junction Box:
(optional)

This must be used with 60 and
above horsepower pumps and
with all systems if the electrical
control panel is to be set remote
from the pumps. The Hydromatic
NEMA 4 junction box is provided
with com pres sion connectors
for sealing all wires. No sealing
compound is needed to make
connections wa ter proof.

Wiring diagrams are provided
with the panel for making
connections. The size wire to use
from panel to sump depends on
motor size and distance in feet.

Be sure each wire is checked so
that a wrong connection will not
be made. An ohmmeter or
Megger can be used to check
wire continuity.

Installing Float Switch
Controls:

The controls are supported by a
mounting bracket that is attached
to sump wall, cover, or to the
NEMA 4 junction box. Cord
snubbers are used to hold the cord
in place. Control level can be
changed at any time by loosening
the snubber and readjusting
cord height.

In either duplex or triplex
systems, the bottom of the lower
or turn-off control is set just above
the top of volute, so that the
volute will always be submerged
during the pumping cycle. The
second, or turn-on control, is set
about 24 inches above the lower
turn-off control.

More distance between turn-on
and turn-off controls can be used,
but sewage may become septic,
and excessive solids may collect
for the pump to handle. A frequent
pumping cycle is recommended
for best operation.

In a duplex system the third or
override control is usually set
about 6 inches above the one
pump turn-on control.

In a triplex system the third or
override control is usually set
24 inches above the one pump
turn-on control, and the fourth
or second override control is 24
inches higher.

If an alarm system is used, this
control is usually set about 6
inches above the override control.

Making Electrical Connections:

All electrical wiring must be in
ac cor dance with local codes, and
only competent electricians should
make the in stal la tions. Complete
wiring diagrams are glued to the
inside cover of the panel. All wires
should be checked for grounds
with an ohmmeter or Megger after
the con nec tions are made. This is

important, as one grounded wire
can cause considerable trouble.

IMPORTANT: If equipment is
not properly wired and protected
as rec om mend ed, the warranty
is void.

Pump
Operations

Starting System:

1. Turn H-O-A switch to
Off position and then turn on
main circuit breakers.

2. Open all discharge valves and
allow water to rise in sump.

3. Turn H-O-A switch to Hand
posi tion on one pump and
notice oper ation. If pump is
noisy and vibrates, rotation
is wrong. To change rotation,
interchange any two line leads
to motor 3ø only. Do not
interchange main incoming
lines. If duplex system, check
second pump in same manner.

4. Now set both H-O-A switches
to Auto position and allow
water to rise in sump until
one pump starts. Allow pump
to operate until level drops to
turn-off point.

5. Allow sump level to rise to
start other pump. Notice run
lights on panel. Pumps should
alternate on each successive
cycle of op er a tion.

6. Turn both H-O-A switches
to Off position and allow

sump to fill to the override
control level.

7. Turn both switches to Auto
position and both pumps should
start and operate together until
level drops to turn-off point.

8. Repeat this operation cycle
several times before leaving
the job.

9. Check voltage when pumps
are operating and check the
amp draw of each pump.
Check amps on each wire,
as sometimes a high leg
will exist. One leg can be
somewhat higher (5 to 10%)
without causing trouble. For
excessive amp draw on one
leg, the power company should
be consulted.

As the motors are oil filled, no
lubrication or other maintenance
is required.

Generally, these pumps give
very reliable service, and can
be expected to operate for many
years on normal sewage pumping
without failure.

Field Service on Motor:

Submersible motors out of
warranty can be serviced in
the field by any reliable motor
service shop. Any pump in
warranty must be returned to the
factory for service or repaired
at an authorized Hydromatic
service center. Charges will not be
allowed if in warranty pump is not

service center.

When field service is performed
on a pump, these instructions
should be carefully followed.

Replacing Stator:

1. If stator only is damaged,
it may not be necessary to
completely dismantle pump
as stator and housing can be
lifted from pump without
disturbing seals or bearings.

2. Drain all oil from upper
housing, remove drain plug in
bottom of stator housing and
remove plug in top of housing
to allow air to enter.

3. After chamber is drained,
remove hold-down bolts
and lift off. Use care in
lifting as the seal failure
connecting wire must be
dis con nect ed before housing
is com plete ly removed.

4. Set assembly on bench and
remove connection box. When
box is lifted off, connection
wires to motor will be exposed.
These wires will probably be
burned, but each wire is tagged
with a metal marker giving
wire number. Cut the wires.

If the leads to the connection

box are burned, a complete
new con nec tion box with new
wire must be used. The wires
are potted in with sealing

compound and a new unit
must be obtained from
the factory.

5. The stator is held in the
housing with a bolted-in
retaining ring and prevented
from rotating by a key.

6. Remove the retaining ring and
socket head cap screw.

7. After ring is removed, turn
housing upright and bump on
hard wood blocks. This should
jar the stator loose and allow it
to drop out.

8. Thoroughly clean housing
before replacing new stator.
Replace stator and make all
wire con nec tions to connection
box before replacing housing
on pump. This is important as
leads must be tucked behind
the windings by using hands
up through rotor core.

Do not tape leads as oil will
de te ri o rate the tape and cause
damage to stator and bearings.

9. Check top bearing. If clean and
does not turn rough, bearings
can be reused and it is not
necessary to completely
dismantle pump to change
bearings. If bearings are
damaged with dirt or heat,
they must be re placed.

10.Replace stator housing onto
seal chamber and bolt in place.
Be sure seal failure wire is
connected before housing is
assembled. Be sure back-off
screws have been loosened
so that parts can come metal
to metal. Be sure O-ring seal
has been replaced. If O-ring
is nicked or cut, replace with
new ones. This applies to all
O-rings used in assembly.

11.After all leads are reconnected
in the connection box, make
a high voltage ground test

on each wire. The only wire
that should show ground is
the green power lead and the
ground lead in the auxiliary
control cable.

12.For safety, complete pump
should be air checked under
water for leaks. Lay pump on
side for this oil filling with
oil fill hole upright. Do not
completely fill; leave oil about
1 inch below plug hole. Use
only Hydromatic submersible
oil in this chamber. Replace
plug; use Permatex on threads.
Install air valve in top plug
opening of motor housing and
charge housing with about
10 psi of air. Be sure air is dry.
Do not use air line where water
may be trapped in the line.
Submerge complete unit under
water and check for leaks.

13.Refill motor chamber with
oil. Use Hydromatic special
sub mers ible oil. Fill chamber
until oil covers top of the
windings. Leave air space in
the top for expansion. Use
Permatex on plug threads.

Replacing Seals and Bearings:

1. Drain all oil from motor
chamber and seal chamber
as described.

2. Remove motor housing
as described.

3. Remove bolts that hold seal
chamber to pump housing.
Use back-off screws to break
loose. With hardwood block,
tape end of impeller to loosen
from shaft. When free, remove
impeller from shaft.

4. Lift rotating assembly from
pump case and place on bench.

5. Impeller Removal: Hold rotor
and remove bolt and washer
from impeller end of shaft,
then thread bolt back into shaft.

The impeller is keyed to the
shaft, so by using a screwdriv­er on opposite sides behind the
im pel ler, apply force then tap
on the end of the bolt to break
impeller loose from taper shaft.
Remove impeller.

6. Remove key and pry on each
side of shoulder of shaft sleeve
to remove. Seal should come
off with sleeve. If sleeve is not
free, leave in place and push
off when seal plate is removed.

7. To remove seal plate take
out socket head flat screws
and using screws in back-off
holes pry plate loose. This
will also force seal off if not
already re moved.

8. Remove snap ring that holds
upper seal. Pull seal if it is free.
If not free, it can be forced off
when shaft is removed.

9. Set seal housing assembly in
upright position and bump end
of shaft on hardwood block.
This will push the bearing
from the housing and will force
upper seal from shaft.

10.Use bearing puller to remove

bearings. Replace with new
bearings. Press only on the
inner face of bearing when
replacing. Pressing on outer
face can damage the bearing.

IMPORTANT—Do not use any
of the old seal parts. Replace
with all new seals.

11.Thoroughly clean all castings

before replacing seals. One
grain of dirt between the seal
faces can cause failure.

12.Examine all O-Rings for nicks

before reusing.

13.Be sure key is in place in

notch of shaft sleeve to prevent
sleeve from turning.

14.Use Locktite

®

on socket head

locking screw in end of shaft.

5

15.Before refilling chamber
with oil, air test as described
above and refill both chambers
with oil.

16.Always check all leads with
high voltage or with Megger
for grounds before operating
the pump.

Pump
Troubleshooting

Below is a list of common
problems and the probable causes:

Pump will not start.

Pump operates with selector
switch in Hand position but will
not operate in Auto position.

1. This indicates trouble in
the level control or the
alternator relay.

2. Check control panel for trouble.

Pump runs but will not shut off.

1. Pump may be air locked.
Turn pump off and let set for
several minutes, then restart.

2. Lower float control may be
hung-up in the closed position.
Check in sump to be sure
control is free.

3. Selector switch may be in the
Hand position.

Motor stops and then restarts
after short period but overload
heaters in starter do not trip.

1. This indicates heat sensors
in the motor are tripping due
to ex ces sive heat. Impeller
may be partially clogged
giving a sus tained overload
but not high enough to trip
overload heater switch.

2. Motor may be operating
out of liquid due to a failed
level control.

3. Pump may be operating on
a short cycle due to sump
being too small or from water
returning to sump due to a
leaking check valve.

1. No power to the motor.
Check for blown fuse or open
circuit breaker.

2. Selector switch may be in the
Off position.

3. Control circuit transformer
fuse may be blown.

4. Overload heater on starter may
be tripped. Push to reset.

Pump will not start and
overload heaters trip.

1. Turn off power and check
motor leads with Megger or
ohmmeter for possible ground.

2. Check resistance of motor
windings. All 3 phases should
show the same reading.

3. If no grounds exist and
the motor windings check
OK, remove pump from sump
and check for clogged or
blocked impeller.

Pump does not deliver proper
capacity.

1. Discharge gate valve may
be partially closed or
partially clogged.

2. Check valve may be partially
clogged. Raise level up and
down to clear.

3. Pump may be running in
wrong direction. Low speed
pumps can operate in reverse
direction without much noise
or vibration.

4. Discharge head may be
too high. Check total head
with gauge when pump is
operating. Total head is
discharge gauge pressure
converted to feet plus vertical
height from water level in
sump to center line of pressure
gauge in discharge line. Gauge
should be installed on pump
side of all valves. Multiply
gauge pressure in pounds by

2.31 to get head in feet.

6

5. If pump has been in service for
some time and capacity falls
off, remove pump and check
for wear or clogged impeller.
