The Stanley Fisher HSF Series is a horizontal split case centrifugal pump engineered for high capacity municipal, industrial, HVAC, and water transfer applications. The double suction impeller design promotes hydraulic balance, reduced radial loading, and stable long term operation.
The axially split casing allows access to internal rotating components without disturbing piping connections, simplifying inspection and maintenance in critical service environments.
HSF pumps are supplied with flanged suction and discharge connections and are available in multiple sizes and configurations for 50 Hz and 60 Hz installations. Construction options support a wide range of operating pressures and application requirements.
The HSF Series features a horizontally split casing design that allows access to the internal rotating assembly without removing the pump from the piping system. This configuration simplifies inspection, seal service, and internal maintenance in high capacity installations.
Double suction impeller geometry promotes hydraulic balance and reduces radial thrust, supporting smooth operation and extended bearing life under continuous duty conditions.
Pumps are supplied with flanged suction and discharge connections and are manufactured in robust cast iron construction, with material options available to suit municipal, HVAC, and industrial service requirements.
