2-Inch Thermoplastic Dewatering Pumps
Refer to pump manual 1808-633-00 for General Operating and Safety Instructions.
IMPORTANT: Not for use with petroleum based liquids.
MAINTENANCE
To prevent Accidental starting always remove spark plug, or disconnect
and ground spark plug wire before attempting to service or remove any
component.
MECHANICAL SEAL REPLACEMENT
Refer to Figures 1, 2, and 3.
IMPORTANT: Replace seal seat, (Ref. No. 22) and seal head (Ref. No. 23) at
the same time to ensure proper mating of mechanical seal components!
1. Unthread fasteners (Ref. No. 16), nuts (Ref. No. 25) and remove casing
(Ref. No. 15) and casing seal (Ref. No. 7) from adapter (Ref. No. 3).
Unthread fasteners (Ref. Nos. 11 and 19) and remove volute (Ref. No.
20) and volute seal (Ref. No. 6) from adapter.
2. Unthread impeller fastener (Ref. No. 10) and remove impeller (Ref. No.
9), impeller seal (Ref. No. 4) and shims (Ref. No. 21).
NOTE: To keep shaft from turning, hold impeller while unthreading impeller
fastener.
3. Pry seal seat from impeller recess with a screwdriver (See Figure 1).
4. Remove adapter by unthreading adapter fasteners (Ref. No. 5) and
fastener seals (Ref. No. 4). Press old seal head and adapter seal (Ref.
No. 24) out of adapter by pushing from engine side.
5. Clean adapter and impeller seal recesses
6. Carefully wipe polished surface of new seal seat with a clean cloth.
7. Wet rubber portion of seal seat with a light coating of soapy water.
8. Press seal seat squarely into recess in impeller. If seal seat does not
press squarely into recess, it can be adjusted by pushing on it with a piece
of pipe. Always use a piece of cardboard between pipe and seal seat to
avoid scratching lapped, highly polished surface of seal seat (handle it
carefully).
9. After seal seat is in place, ensure that it is clean and has not been marred.
10. Using a clean cloth, wipe shaft and make certain that it is completely clean.
11. Place adapter seal (O-ring) onto seal head behind ange and press
assembly into adapter as shown in Figure 2.
Do not touch or wipe polished face of seal head.
12. Secure adapter on pedestal mounting face, using fasteners and fastener
seals. Be sure to replace gasket (Ref. No. 31) between engine and
adapter, if removed during disassembly.
DESCRIPTION
These centrifugal pumps include a EPDM/EPR mechanical seal with stainless steel spring, O-rings and a built-in check valve for better self-priming capabilities
(up to 20 ft. suction lift). Clog resistant impeller is capable of handling solids up to 7/16” diameter. Pumps include molded carrying handle, and two 2” NPT pipe
nipples (optional rubber foot pads available). Handle liquids from 40º to 130º F (4º to 54º C). For use with nonammable, non-abrasive liquids compatible with
pump component materials.
Applications include pumping clear, clean water, salt water, and some liquid fertilizers and herbicides. An optional EPDM Seal/O-ring/Flapper Kit (see Repair
Parts List) is available for pumping “Alachlor Herbicides” (such as Monsanto’s Lasso). If the fertilizer or herbicide is not compatible with Buna-N (standard) or
EPDM (optional) rubber materials, do not use these pumps.
For use with nonammable liquids that are chemically compatible with pump component materials.

Tighten adapter fasteners evenly to avoid cocking or damaging adapter.
13. Replace impeller and shims, ensuring that key (Ref. No. 8) is in place and
lock impeller to shaft with fastener and impeller seal on fastener.
14. Replace volute seal and volute with fasteners, ensure that check valve
(Ref. No. 12) is in place then remount casing seal and pump casing with
fasteners and nuts.
IMPORTANT: Always inspect all seals when unit is disassembled. Replace
when rubber is hard, cracked, or worn.
When reassembling parts with O-ring seals or gaskets, it is sometimes helpful
to apply a small amount of soapy water on O-ring so that parts slide over O-ring
without pinching or shaving it.
SHIM ADJUSTMENT
When installing a replacement impeller or mechanical seal, it may be necessary
to vary the number of shims (Ref. No. 21) that will be required. This is easily
done by adding one 0.010” shim more than was removed and reassembling
pump as described.
Ensure that casing is snugly in place and check shaft to make sure it is turning
freely. If it turns freely, check to ensure that adapter (Ref. No. 3) and casing
(Ref. No. 15) are tted tight together. If they are not, tighten fasteners (Ref.
No. 16) and recheck shaft for free turning. Tighten carefully, turning shaft while
tightening. If shaft seizes before fasteners (Ref. No. 16) are completely tight,
disassemble pump and remove one shim and repeat reassembly.
If any time during above operation shaft does not turn free, follow procedure
indicated above and repeat procedure.
Above procedure ensures that pump will have proper running clearance (less
than 0.010”) between impeller and casing and perform like a new unit with new
impeller or motor.
