Periodic maintenance and inspection is required on all pumps to insure proper operation. Unit must be clear of debris and sediment. Inspect for leaks and loose bolts. Failure
to do so voids warranty.
1 ½ & 2-Inch Trash Pumps
Refer to pump manual 1808-633-00 for General Operating and Safety Instructions.
DESCRIPTION
These centrifugal pumps are engine-driven, self-priming (to 20 ft. lift) portable units, shipped completely assembled and mounted. Pumps include a clog
resistant, open impeller capable of handling solids as large as 3/4" diameter for 1-1/2" NPT pumps and 1" diameter for 2" NPT models (up to 25% by
volume). A built-in check valve assists in priming and a Viton/Silicon Carbide mechanical seal prevents leakage. Handles liquids from 40º to 180º F (4º to
82º C). For use with nonflammable liquids compatible with pump component materials.
SPECIFICATIONS
Suction Inlet………………………………………………..1-1/2" or 2" NPT
Discharge Outlet…………………………………………..1-1/2" or 2" NPT
Basic Construction…………………………………………………Cast Iron
MAINTENANCE
To prevent accidental starting always remove the spark plug, or
disconnect and ground the spark plug wire before attempting to service
or remove any component.
CLEANING
This unit has been designed with a removable volute enabling the
pump to be cleaned or unclogged with ease. Remove casing and
volute as described in steps 1 and 2 under MECHANICAL SEAL
REPLACEMENT. Remove any debris found inside the unit,
reassemble as described in steps 16 and 17 under MECHANICAL
SEAL REPLACEMENT.
NOTE: Depending on application, it may be necessary to remove
suction and discharge hoses.
MECHANICAL SEAL REPLACEMENT
Refer to Figures 1 and 2
IMPORTANT: Always replace the seal seat (Ref. No. 5), seal head
(Ref. No. 6), and shaft sleeve (Ref. No. 7) to insure proper mating of
mechanical seal components.
1. Unthread cap screws (Ref. No. 14) and remove casing (Ref.
No. 12) and O-ring (Ref. No. 4) from the adapter (Ref. No.
3).
2. Unthread round head screws (Ref. No. 15) and remove
volute (Ref. No. 10) from adapter.
3. Unscrew impeller (Ref. No. 9) from the engine shaft.
Remove the impeller shim(s) (Ref. No. 8), shaft sleeve and
seal head from engine shaft.
NOTE: To keep the shaft from turning, remove the shroud from the
engine and hold the flywheel in place.
4. Unthread hex flange screw (Ref. No. 2) 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.
7. Carefully wipe the ceramic surface of the new seal seat with
a clean cloth.
8. Wet the outside of 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. Use finger pressure only 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, insure 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.
Tighten hex flange 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 with the
black carbon face toward the white ceramic seal seat.
Do not touch or wipe the face of the Polished surface part of the
seal head.
14. Replace any impeller shim(s) removed in disassembly.
15. Screw impeller back in place, tightening until it is against the
shaft sleeve.
16. Remount volute and position O-ring in place.
IMPORTANT: Always inspect O-ring. Replace when cracked or worn.
Wet O-ring with soapy water for ease of assembly.
17. Remount casing.
SHIM ADJUSTMENT
1. When installing a replacement engine, adapter, impeller,
shaft sleeve, volute or casing it may be necessary to vary
the number of impeller shims (Ref. No. 8) 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.
NOTE: When adding or removing shims, it is best to proceed with a
0.010" increment each time. Remove spark plug wire from engine and
ground. While tightening the unit together, turn the shaft (by pulling on
the recoil starter etc.); feel for the shaft seizing. If shaft begins to seize
before the fasteners are completely tight, disassemble the pump and
remove one shim and repeat assembly.
2. Once having added one shim more than original, ensure that
the volute (Ref. No. 10) and adapter (Ref. No. 3) are firmly
fitted (check fasteners, Ref. Nos. 2 & 15). When engine
turns freely, add shims until it does strike, then remove a
0.010" shim. This should allow the proper clearance.
3. Proper running clearance for the impeller should be as close
as possible to volute without striking; maximum clearance is
1/32" (0.032").
4. Follow the above procedure until proper clearance is
obtained. This will insure maximum performance.
