Pumps Not Operating or in
Storage:
Pumps with carbon ceramic seals
must have impellers manually
rotated (6 revolutions) after setting
non-operational for 3 months
or longer and prior to electrical
start-up.
2
Pumps with tungsten carbide seals
must have impellers manually
rotated (6 revolutions) after setting
non-operational for 3 weeks or
longer and prior to electrical
start-up.
Seal Failure:
An electrode is installed in the seal
chamber so if any water enters the
chamber through the first seal the
electrode will be energized and a
signal will be trans mit ted to the
sen sing unit at ground surface
causing a red light to turn on.
The elec trode 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, but the seal should be
checked im medi ate ly after failure
is indicated.
The sensing unit is recommended
on all installations as good
insurance against motor failure.
Pump:
The submersible pumps in this
manual are supplied for 1 and 3
phase and for 200, 230, 460 or
575 volts. Power cable is supplied
with the green wire for ground. Be
sure green wire is connected to a
good ground such as water pipe or
ground stake.
Heat Sensors:
All motors have heat sensor units
em bed ded in the motor winding
to detect ex ces sive heat. The
heat sen sors are set to trip at
130°C. The sensors au tomatically
reset when motor cools to
safe temperature.
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.
IMPORTANT: If Hydromatic®
electrical starting equip ment is
not supplied, the heat sensor
circuit must be connected in
series with the starter coil
or warranty is void.
Sump Level Control:
Sump level is controlled by
Hydromatic switch controls. The
float is held in position in the
sump by a weight attached to
the power cord above the float.
The cord supports the float
and is adjusted for height from
the surface.
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. Extra floats
with ap propriate controls can
be supplied for alarm functions.
Triplex systems use four controls:
one set at turn-off, one set at turnon for one pump, one set at turnon 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.

Installation
Instructions
Electrical Control Panel:
It is recommended that the
Hydromatic control panel be used
with all pumps as proper starter
heat ers and connections for heat
sensor wires are fur nished.
Hydromatic® electrical equipment
NEMA 3R enclosure. The
electrical equipment 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, and an electric
alternator and a transformer to
provide appropri ate control for
control circuit and alarms.
Overload Heater:
Starters with 3 leg overload
protection must be supplied if
the Hydromatic electrical panel
is not used. The heaters must
be sized in accordance with the
nameplate amps on the motor. The

Installing Pump in Sump:
Before installing pump in sump,
lay it on side and turn impeller
manually. Im pel ler may be slightly
stuck due to factory test water,
so it must be bro ken loose with
small bar or screwdriver in edge
of vanes. 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 the line pressure can be cut
off if necessary to service the
check valve. Single pump systems
are sometimes installed without a
check valve where it is desirable
to self-drain the dis charge line to
prevent freezing. This can be done
Sensor Wires Ground Wires
only with short discharge lines.
Otherwise water will return to the
sump and cause short cycling of
the pump.
NEMA 4 Junction Box
(Optional):
A NEMA 4 junction box should
be used to make power and control
con nec tions if electrical control
panel is to be set remote from
the pump sump. The Hydromatic
NEMA 4 junction box is provided
with com pres sion con nec tors
for sealing all wires. No sealing
compound is need ed to make
connec tions wa ter proof.
Wiring diagrams are provided with
the panel for making connections.
The size wire to use from the panel
to sump de pends on motor size
and distance in feet.
Be sure each wire is checked
out so that a wrong connection
will not be made. An ohm me ter
or Megger can be used to check
wire continuity.
Installing Switch Controls:
The controls are supported by a
mount ing 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 length.

In either a simplex or duplex
system, 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 sec ond,
or turn-on control, is set about
24 inches above the lower
turn-off con trol.
More distance between turn-on
and turn-off controls can be used,
but sew age may become septic,
and excessive solids may collect
for the pump to handle. A frequent
pumping cycle is recommended
for best op er a tion.
If an alarm system is used,
this con trol 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 installations.
Complete wiring diagrams are
glued to the inside cover of the
panel. All wires should be checked
for grounds with an ohm me ter or
Megger after the connections are
made. THIS IS IMPORTANT,
AS ONE GROUNDED WIRE
CAN CAUSE CON SID ER ABLE
TROU BLE.
IMPORTANT: If equipment
is not properly wired and
protect ed as recommended, the
warranty is void.
Heat Sensors and Seal Failure
Connections:
Be sure heat sensor wires are
connect ed in series with the starter
coil. Connections are provided on
the terminal strip.
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
position on one pump and
notice operation. 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 the
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
op er ate until the 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
po si tion and both pumps
should start and operate
together until level drops to
turn-off point.
8. Repeat this operation cycle
sev er al 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 con sult ed.
Phase Converters:
Phase converters are generally
not recommended, but in cases
where only single phase current
is available, phase converters can
be used. Be sure to size the phase
converter large enough for the
amp draw specified on the motor
nameplate, not necessarily by
motor horsepower. The warranty
on all three phase submersible
motors is void if operated with
single phase power through a
phase converter, and 3 leg ambient
compensated extra-quick trip
overload protectors are not used.

Pump
Maintenance
on a pump, these instructions
should be carefully followed.
Replacing Stator:
Lubrication or other maintenance
is not required, as the motors are
oil filled.
1. If stator only is damaged,
it may not be necessary to
completely dismantle pump
Generally, these pumps give
very reliable service, and can
be expected to operate for many
years without failure under normal
operating con di tions.
as stator and housing can be
lifted from pump without
disturbing seals or bear ings.
2. To drain all oil from upper
hous ing, remove drain plug in
bot tom of stator housing and
Lightning:
In some areas where considerable
lightning occurs, it is recommended
that a lightning arrestor be installed
at the control panel. Lightning
arrestors are good insurance
against damage to an expensive
motor.
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 con necting
wire must be dis con nected
before housing is com pletely
removed.
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 re paired at an authorized
Hydromatic® service center.
Charges will not be allowed if
in warranty pump is not taken
to an authorized Hydromatic
service center.
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
clamp ring.
6. After ring is removed, turn
hous ing upright and bump
on hard wood blocks. This
should jar the stator loose and
allow it to drop out.
7. 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.
IMPORTANT: Use only
compression type insulated
connectors on the wires.
Do not tape leads as oil will
de te ri o rate the tape and
cause damage to stator and
bear ings.
8. 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 replaced.
Remember to reinstall the
upper bearing load spring.
9. Replace stator housing onto
seal chamber and bolt in place.
BE SURE SEAL FAILURE
WIRE IS CONNECTED
BEFORE HOUS ING IS
ASSEMBLED.
Be sure O-ring seal has been
replaced. If O-ring is nicked
or cut, replace with new one.
This ap plies to all O-rings
used in as sem bly.

10. 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 aux il ia ry
control cable.
11. 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
the plug hole. Use only
Hydromatic® submers ible oil
in this chamber or high grade
trans form er oil. Re place the
plug; use Permatex on threads.
Install air valve in top plug
open ing 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.
12. Refill motor chamber with oil.
Use high grade transformer
oil or Hydromatic special
submers ible oil. Fill chamber
until oil covers top of the
windings. Leave air space
in 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
cham ber to pump housing.
Use back-off screws to
break loose. With hardwood
block, tap end of impeller to
loosen from shaft. When free,
remove impeller from shaft.
4. Lift rotating assembly
(rotor, shaft and impeller)
from pump case and place
horizontally 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
impeller, apply force, then tap
on the end of the bolt to break
impeller loose from taper
shaft. Remove impeller.
IMPORTANT: The impeller
is designed to be selftightening when running,
so impeller may be difficult
to break loose. If this is the
case, use plastic or rubber
hammer on im pel ler tip to
free. Remove impeller.
6. Remove lower seal spring and
pry out seal with screwdriver.
7. To remove seal housing, take
out socket head bolts and
using bolts in back of holes,
pry plates loose. This will
force out lower seal if not
already removed.
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. Remove 4 bolts that hold
bearing housing in place. Set
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
bear ings. 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 using.
13. Use Locktite® on socket head
locking screw in end of shaft.
Pump
Troubleshooting
Below is a list of common
problems and the probable causes:
Pump will not start.
1. No power to the motor. Check
for blown fuse or open circuit
break er.
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
wind ings. 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 float level control or the
alternator relay.
6
Page 7
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.
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.
1. This indicates heat sensors in
the motor are tripping due to
ex ces sive heat. Impeller may
be par tial ly clogged giving
a sustained overload but not
high enough to trip overload
heat er 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
re turn ing to sump due to a
leaking check valve.
3. Pump may be running in
wrong direction. Low speed
pumps can operate in reverse
di rec tion with out much noise
or vibration.
4. Discharge head may be
too high. Check total head
with gauge when pump
is operating. Total head is
dis charge 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.
