Operating Instructions & Parts Manual

020598 and 020599

Self-Priming Engine-Driven
Centrifugal Pumps

Please read and save these instructions. Read carefully before attempting to assemble, install,
operate or maintain the product described. Protect yourself and others by observing all safety
information. Failure to comply with instructions could result in personal injury and/or proper-
ty damage! Retain instructions for future reference.

Description

These centrifugal pumps include a precision mechanical seal with stainless steel
spring, EPDM seals, carbon face and ceramic seat, 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, rubber foot pads, and two 2" NPT pipe nipples. 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 fertil-
izers and herbicides. An optional Buna N Seal/O-ring/Flapper Kit (see Repair Parts
List) is available for pumping additional liquids. If the liquid is not compatible with
Buna-N (optional) or EPDM (standard) rubber materials, do not use these pumps.
