56-frame 2 hp spa pump for hot tubs

This 56-frame spa pump delivers a 120 Gallons Per Minute flow rate at 230 V for hot-tub circulation. The two-speed motor lets you match output to filtration or jet demand. A Viton shaft seal resists chemical wear for longer service life. The wet end rotates in 90-degree increments to suit varied plumbing layouts.

Rotatable wet end and Viton seal benefits

The wet end can be turned every 90 degrees so inlet and outlet ports align with existing pipework without extra fittings. Viton shaft seals withstand sanitiser exposure better than standard elastomers, reducing leak risk. The 56-frame motor runs cooler, which extends bearing and winding life. Two-speed operation cuts energy use during low-flow cycles.

Voltage and plumbing checks before ordering

Confirm your spa control system supplies 230 V single-phase power and that the breaker and wire gauge match the motor’s nameplate rating. Verify the pump’s port size and orientation suit your current plumbing or that you have fittings to adapt. Ensure the equipment pad can accommodate the 56-frame motor footprint and that local codes permit the installation.

Questions about this item

How often does the Viton shaft seal need replacement?

Viton shaft seals are designed for long service life in hot-tub chemistry; inspect annually and replace only if leakage appears around the motor shaft.

What limits continuous high-speed operation first?

The 2 hp 56-frame motor reaches its thermal limit before the 120 GPM wet end restricts flow during sustained high-speed runs.

How loud and hot does the 230 V pump get running all day?

The 56-frame design runs cooler than smaller frames, and two-speed operation lets you use low speed for quiet, low-heat circulation most of the day.
