Product Overview

The Pentair TP Series Pump Body | 17303-0001Z is a genuine Pentair replacement pump body (volute) for Pentair / Sta-Rite TP Series Dyna-Jet pool and spa pumps. The pump body forms the main water chamber of the wet end, housing the impeller and directing water from the suction port through the pump and out the discharge port.

This replacement is the right repair when the original pump body is cracked, leaking, warped, or has damaged threaded ports from freeze expansion, over-tightened fittings, or age. Replacing the pump body can restore proper pump operation without replacing the complete pump.

Benefits

The Pentair 17303-0001Z restores the main wet-end body of a compatible Dyna-Jet pump. A cracked or leaking pump body can cause the pump to lose prime, pull air, leak water, or move water inefficiently.

Using a genuine Pentair replacement helps ensure correct fit with the existing seal plate, impeller, diffuser, and plumbing connections. This makes it a practical repair when the motor and other pump components are still serviceable.

Confirm Before Ordering

Confirm your exact pump model and existing part number before purchasing. This pump body is used on Pentair / Sta-Rite TP Series Dyna-Jet pumps, but compatibility can vary by pump version and production date. Do not order based on motor horsepower or pump appearance alone.

For best repair results, inspect the seal plate O-ring, shaft seal, impeller, diffuser, and drain plugs while replacing the pump body. Always shut off power and relieve pressure before servicing, and have pump repairs performed by a qualified pool professional when needed.
