Product details

The Sta-Rite CSP Series is Pentair cast iron commercial pump line, and CSPHK3-142 is the 7.5 HP three phase version at 230-460V, supplied without a strainer.

Commercial duty

Cast iron is the difference between this and a residential pump. A commercial pool runs long hours against real head, and the CSP body is built for that rather than for a backyard duty cycle. At 7.5 HP it belongs on a system sized for the flow, not on an oversized residential pad.

Power and plumbing

The motor is NEMA three phase and wired for 230-460V, so three phase power has to be available and the wiring has to be done by someone qualified to land it. Because this version has no strainer, the system needs a separate strainer or hair and lint pot ahead of the pump to keep debris out of the impeller.

Before you order

Match the part number. The CSP range splits by horsepower, phase, voltage and whether a strainer is fitted, and those variants look alike on a spec sheet.
