The Stanley Fisher KPA Series is available in both close-coupled and split-coupled configurations. These threaded in-line centrifugal pumps are engineered for continuous circulation of clean liquids in closed-loop HVAC, hydronic heating, and commercial mechanical systems.
Designed for direct installation into horizontal piping, the in-line configuration minimizes system footprint while maintaining hydraulic efficiency and mechanical stability. Split-coupled construction allows service access without disturbing piping connections.
KPA pumps feature FNPT threaded connections up to 1-1/4 inch and are rated for a maximum working pressure of 145 PSI (PN10 equivalent). Units are available in 50 Hz and 60 Hz configurations with 2-pole and 4-pole motor options.
Split-coupled construction allows service access without disturbing piping. In-line casing configuration installs directly into horizontal piping systems.
Threaded FNPT connections up to 1-1/4 in. Standard construction in cast iron with bronze construction available. Maximum working pressure 145 PSI (PN10 equivalent).
