Vertical Sealless Sprayer/Washer
Pumps

Refer to form 1608-634-00 for General Operating and Safety Instructions and applicable Warranty.

Description

Vertical sealless sprayer/washer pumps are heavy duty industrial units designed for
OEM, automotive and industrial washing machines, parts cleaners, spray booths and
cooling towers. Pumps are immersion type; pump end must be immersed in liquid,
motor must remain above liquid surface.

All models feature 316 stainless steel semi-open clog resistant impeller, stainless steel
shaft, steel shaft coupling, cast iron base and column, plated steel inlet screen, and a
TEFC (Totally Enclosed Fan Cooled) electric motor. Motor has ball bearings. Heavy­duty steel universal mounting brackets included. Pump design eliminates a bottom
bearing and a shaft seal on all models. Pumps handle liquids up to a maximum
temperature of 200° F. Maximum ambient temperature 104° F. Liquid viscosity cannot
exceed 100 SSU. These are manual units; no controls are supplied. For use with
nonflammable liquids compatible with pump component materials.

Installation

1. (5570 series pumps) Remove
shipping fixture (Ref. No. 19) that
holds the drive shaft to the base
before installing pump.

2. Pump must be installed with its
base supporting the entire weight of
the pump.

CAUTION Mounting brackets are
not designed to support the
pump’s weight. Brackets are
designed to prevent tipping.

3. Position pump in tank or reservoir.
Position mounting brackets, align
pipe clearance hole with pump
discharge outlet.

(4445 series pumps)

4. Assemble one piece of sponge tape
(Ref. No. 25) to each clamp bracket
(Ref. No. 24). Attach clamp brackets to
mounting brackets with fasteners
provided (Ref. Nos. 26 and 27). This
will fix the column (Ref. No. 3) in
position.

(5570 series pumps)

4. Adjust lower fasteners (Ref. No. 4)
to bottom of mounting brackets.
Secure pump to mounting brackets
with upper fasteners (Ref. No. 4).

5. Secure mounting brackets to tank
or reservoir. Install an appropriate
fastener in each hole or slot provided.

6. Install the balance of the system.

Vertical Sealless Sprayer/Washer Pumps

Maintenance

WARNING Make certain that unit

is disconnected from power
source before attempting to
service or remove any component.

IMPELLER/MOTOR REPLACEMENT

Refer to Figure 2, and 3.

1. Remove unit from the tank or
reservoir.

2. Remove fasteners (Ref No. 8) and
washers if present (Ref. No. 7) that
connect the volute base (Ref. No. 17)
to the volute cover (Ref. No. 10).

3. Remove volute base, and gasket
(Ref. No. 16).

4. Place an allen wrench through the
slot in the top of the column and into
one of the socket head screws of the
shaft coupling. Rotate impeller
counterclockwise until allen wrench
stops against side of slot. Remove nut
(Ref. No. 15) and then impeller from
drive shaft by rotating each
counterclockwise.
IMPORTANT: Care should be taken to
insure that same number of shim
washers (Ref. No. 9), if present, is
replaced behind impeller as were
removed. These shim washers are
located directly behind the impeller.
Shim washers may or may not be
present depending on assembly
clearances.

5. Remove allen wrench from slot and
then remove the four fasteners (Ref.
No. 5) and washers or nuts (Ref. No. 4)
that connect the motor (Ref. No. 1) to
the column (Ref. No. 3).

6. Remove the motor with shaft (Ref.
No. 13) and coupling (Ref. No. 2) from
the column.

7. Measure the distance from the
shaft coupling to the motor mounting
surface. Record this measurement.

8. Loosen the two socket head screws,
towards the motor, in the coupling.
Slide the coupling/shaft from the
motor.

9. To reassemble, slide the
coupling/shaft on the motor. Replace
drive key (Ref. No. 7) if removed (557?
Series only). Position the coupling at
the recorded distance from the motor

mounting surface. Securely tighten all
four socket head screws in coupling.

10. Install motor/shaft assembly into
column. Secure with four fasteners
and washers.

11. Install impeller, shim washers if
any, and nut. Position gasket on
volute cover and install volute base
with fasteners and washers.
IMPORTANT: If impeller strikes volute
spacer plate (Ref. No. 11) before
bottoming on shaft shoulder, add two

0.020” shims behind impeller.
Reinstall impeller.

12. Place pump in an upright position.
Rotate shaft/impeller. Impeller cannot
strike volute base or volute cover. If
interference exists, install or remove
shim washers behind the impeller.
(See “SHIM ADJUSTMENT” section) If
shimming does not correct
interference, repositioning
coupling/shaft/impeller assembly on
motor shaft may be necessary.

VOLUTE SPACER PLATE
REPLACEMENT

The volute spacer plate is subject to
wear only by abrasive liquids. If badly,
worn this plate can be replaced easily.

1. Disassemble pump for access as
described in IMPELLER/MOTOR
REPLACEMENT, steps 1, 2, 3, and 4.

2. Remove two fasteners (Ref. No. 12)
that connect the spacer plate to the
volute cover.

3. Replace spacer plate.

4. Reassemble pump as described in
steps 11 and 12.

SHIM ADJUSTMENT

1. When installing a replacement
impeller (Ref. No. 14), motor (Ref. No.

1), volute spacer plate (Ref. No. 11) or
volute base (Ref. No. 17), it may be
necessary to adjust the number of
shims (Ref. No. 9) to insure proper
running clearance between impeller
and volute base and spacer plate.
Proceed as follows:

NOTE: A proper running clearance
between impeller and volute base is

0.04” to 0.06”.
2

1. For impeller or motor replacement,
add one 0.020” shim in addition to
those removed, if any, originally.

2. Reassemble pump as described in
steps 9, 10, 11, and 12 as described in
IMPELLER/MOTOR REPLACEMENT.

IMPORTANT: Insure that volute base
is snugly in place and check shaft to
make sure it is turning freely (rotate
impeller by using impeller nut Ref.
No. 15 and socket wrench). Tighten
fasteners connecting motor to column
and volute to base carefully. Rotate
shaft while tightening so that motor
bearings are not damaged in the
event that too many shims were
installed. If shaft seizes before
fasteners are completely tight,
disassemble pump and remove two
shims and repeat assembly.

SHAFT SUPPORT REMOVAL

Models 4445-95 and 4446-95 only.

These units are designed to operate
without a bottom bearing. A shaft
support (Ref. No. 20) is installed at the
factory to protect the shaft from
misalignment during shipping. If
pump is noisy while operating, this
support may be the cause. The shaft
support can be removed to stop noisy
operation. Shaft support should not
be replaced.

1. Disassemble pump for access as
described in IMPELLER/MOTOR
REPLACEMENT, steps 1 through 6.

2. Press out shaft support. Do not
remove support plate (Ref. No. 21).

3. Reassemble pump as described in
steps 10, 11, and 12.

DEBRIS SCREEN CLEANING

Sprayer/Washer pumps are equipped
with a debris screen (Ref. No. 18). This
screen is supplied attached to volute
base (Ref. No. 17) with 4 drive pins.
This screen may be replaced if
damaged.

If pump performance is reduced or
severe vibration occurs during
operation this screen may be clogged.
Debris screen must be thoroughly
cleaned to restore pump
performance.
