2-Inch Thermoplastic Dewatering Pumps
Refer to pump manual 1808-633-00 for General Operating and Safety Instructions.
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 nonflammable, 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 nonflammable liquids that are chemically compatible with pump component materials.
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.
