Periodic maintenance and inspection is required on all pumps to ensure proper operation. Unit must be clear of debris and sediment. Inspect for leaks and loose bolts. Failure
to do so voids warranty.
IPT Trash Pumps
Refer to pump manual 1808-633-00 for General Operating and Safety Instructions.
DESCRIPTION
This trash pump is a heavy duty, centrifugal, engine-driven, self-priming (to 20 ft. lift after initially filling casing with liquid),
portable unit. Pump is equipped with precision lapped mechanical seal to reduce the likelihood of leakage, and a clog-
resistant impeller capable of handling solids, 4" models up to 2" diameter. Units are used to handle water containing
stones, sticks, mud and other solids (up to 25% by volume). Sealed flange connections facilitate easy removal of suction
and discharge lines. Handles liquids from 40º to 180º F (4º to 82º C). For use with nonflammable fluids compatible with
pump component materials.
All models come standard with manual recoil starter. 4" models feature 12 VDC electric start 5" W x 7¾" L x 5" H battery
holder included. (Battery not included; obtain 12V, 32 amp hour battery from local lawn and garden shop). Pump and
engine are mounted in steel roll frame, requires minimum 2 people to move or lift. Four position discharge manifold
provides a choice in placing hose.
UNPACKING
Refer to Repair Parts Illustration and Repair Parts List to
aid in identifying parts. Unpack and separate all pump
components from container, making sure all parts are
accounted for. Packages should contain:
1. Pump and engine completely assembled in
frame.
2. Battery tray and battery tray hardware (E-start
models only).
3. NPT Strainer.
ASSEMBLY
(Refer to Figure 3)
1. Remove pump from packaging.
2. Electric Start Models Only:
Install a 12 volt type no. 9A1 garden tractor
battery 32 amp hour rating, approx. size 7¾" L x
5" W x 6" H (not included) onto battery tray.
Using hardware included with pump, insert hook
bolts through battery tray holes, thread facing
up. Attach battery box hold down bar across
battery and thread wing nuts onto hook bolts.
3. Refer to engine manual for proper wiring
instructions. Be sure to route and secure battery
cable safely UNDER pump where it will not be
pinched or come in contact with hot engine
exhaust or muffler (see Figure 1)
MAINTENANCE
MECHANICAL SEAL REPLACEMENT
(Refer to Figure 2 and 3)
Disconnect spark plug wire and battery to prevent
accidental starting.
NOTE: Always replace the seal seat (Ref. No. 8), seal
head (Ref. No. 9) and shaft sleeve (Ref. No. 10) to
ensure proper mating of mechanical seal components!

1. Unthread cap screws (Ref. No. 34) and remove
casing (Ref. No. 18) and casing seal (Ref. No. 7)
from adapter (Ref. No. 6).
2. Unthread screws (Ref. No. 14) and remove
volute (Ref. No. 13) from adapter.
3. Unscrew impeller (Ref. No. 12) from the engine
shaft. Remove the impeller shim (Ref. No. 11),
shaft sleeve and seal head from engine shaft.
Use a rubber mallet or soft block of wood to
loosen impeller. Turn it counterclockwise.
4. Unthread cap screws (Ref. No. 4) and remove
the adapter from the engine mounting face.
5. Push seal seat from the adapter recess with a
screwdriver.
6. Clean the adapter recess before inserting a new
seal seat.
Do not touch or wipe the face of the polished part of
the seal head.
7. Carefully wipe the polished surface of the new
seal seat with a clean cloth.
8. Wet the rubber portion of the seal seat with a
light coating of soapy water.
9. Press the new seal seat squarely into the cavity
in the adapter. If the seal seat does not press
squarely into the cavity, it can be adjusted in
place by pushing on it with a piece of pipe.
Always use a piece of cardboard between the
pipe and the seal seat to avoid scratching the
seal seat. (This is a lapped surface and must be
handled very carefully).
10. After the seal seat is in place, ensure that it is
clean and has not been marred.
11. Using a clean cloth, wipe the shaft and make
certain that it is perfectly clean.
12. Secure the adapter on the engine mounting
face.
NOTE: Tighten cap screws EVENLY to avoid cocking
rabbet on engine mounting face.
13. Apply a light coating of soapy water to the inside
rubber portion of seal head and slide onto the
shaft sleeve. Slip the shaft sleeve with seal head
onto the engine shaft.
14. Replace any impeller shims removed in
disassembly.
15. Screw the impeller back in place tightening until
it is seated against shims and shaft sleeve.
NOTE: Check to ensure that the shaft flange (Ref. No. 2)
is in place against engine shaft shoulder.
16. Remount volute with fasteners.
17. Refer to section titled Shim Adjustment at this
time if shaft sleeve or any other parts listed
therein have been replaced.
18. Inspect position of flapper valve assembly (Ref.
No. 16) to ensure proper movement and sealing.
19. Replace O-ring seal on volute rabbet.
NOTE: Always inspect O-ring seals. Replace when
cracked or worn. Wet O-ring with soapy water for ease
of assembly.
20. Remount casing.
21. Remount any other parts and reconnect spark
plug wire and battery (if so equipped). Pump
should now run with renewed original
performance.
SHIM ADJUSTMENT
1. When installing a replacement impeller, engine,
shaft sleeve, adapter, or volute, it may be
necessary to vary the number of impeller shims
(Ref. No. 11) that will be required. This is easily
done by adding one shim more than was
removed and reassembling the pump as
described in Mechanical Seal Replacement
section.
2. Ensure that volute (Ref. No. 13) and adapter
(Ref. No. 6) are fitted firmly (check fastener Ref.
No. 4 and 14). Remove spark plug wire from
engine and turn engine over by pulling the recoil
starter. If engine does not turn freely,
disassemble pump and remove one shim.
NOTE: When adding or removing shims, it is best to
proceed with a 0.010" increment each time. If engine
does turn freely, add shims until it does strike, then
remove a 0.010" shim. This should allow proper
clearance.
3. Proper running clearance is 0.010".
4. Follow the above procedure until proper
clearance is obtained. This will ensure maximum
performance.

IMPELLER AND WEARPLATE
REPLACEMENT
Impeller (Ref. No. 12) and volute/wear plate (Ref. No.
13) are subject to wear only by abrasive sand or
sediment laden liquids. If badly worn, all these parts can
be replaced easily and the pump thus restored to full
efficiency.
NOTE: When the clearance between the impeller and
the volute/wear plate exceeds 1/16" at the face of the
impeller or 1/8" on the outside diameter of the impeller, it
may be necessary to take corrective action. The
increased clearance can cause lengthened priming
times and reduced pumping capacity. If both the priming
and capacity of your unit are satisfactory for your
application, it is recommended that no corrective
maintenance be performed regardless of what
clearances on your unit may have developed, since the
increased clearances in themselves are not generally
harmful to your pump.
Normally, new pump clearances can be restored by
simply shimming behind the impeller. (Add shim
washers, Ref. No. 11). If the impeller is badly worn it is
recommended that the impeller be replaced. This is
usually all that is required since only on unusually
abrasive services does the cast iron wear plate show
deterioration. Occasionally a stone or hard object might
get caught in the impeller and cause damage to the
volute/cutwater. In these cases, follow the instructions
below for replacement and refer to Figure 2.
1. Disassemble pump for access as described in
MECHANICAL SEAL REPLACEMENT, steps 1
and 2.
2. Replace parts as necessary.
NOTE: When replacing volute, attach flapper valve
assembly (Ref. No. 16) to new volute with fasteners
(Ref. No. 17).
NOTE: Before installing new parts, clean all mating
surfaces thoroughly. For information pertaining to the
engine and engine parts, consult the Engine Manual or
contact the nearest authorized service representative or
the manufacturer.
CLEANING
These units are designed so that for most cleanout or
clogging problems it should not be necessary to remove
hoses or piping. The suction area and impeller chambers
can be reached by removing (2) threaded handles (Ref.
No. 25) and removing suction cleanout cover plate (Ref.
No. 27) and gasket (Ref. No. 28).
NOTE: When replacing cleanout cover plate, carefully
wipe clean all surfaces on which the gasket has contact.
Also, make sure the gasket is in position. The screen in
the spark arrester should be checked.
