Waterway - 0.75 HP Impeller for Waterway Centre-Discharge Pumps - 310-5120

Waterway – 0.75 HP Impeller for Waterway Centre-Discharge Pumps

The Waterway 0.75 HP impeller, part number 310-5120 (also listed as 313-0020), is a replacement hot tub pump impeller for selected Waterway centre-discharge pumps. The 0.75 HP figure is a nominal rating, and the actual power of the motor on your pump may be different. We strongly suggest replacing the wet end seal at the same time as the impeller.

Compatibility of the Waterway 0.75 HP impeller

This spa pump impeller is found in some Waterway centre-discharge pumps. It is not described as a universal part, so it is worth confirming that your pump is a Waterway centre-discharge model before you order a replacement.

The 0.75 HP value is the nominal power rating associated with this impeller. Because the actual power of the motor may be different, do not use the horsepower figure alone to decide whether the part is right for your spa.

Cómo elegir el impulsor adecuado

Work through these points before ordering:

• Confirm that the pump is made by Waterway and is a centre-discharge type.
• Compare the part number of your current impeller or pump records with 310-5120 and 313-0020.
• Treat the 0.75 HP rating as nominal, not as the measured output of your motor.
• Check the dimensions in the product image against your existing impeller.

Matching the part number is the most reliable way to avoid ordering an impeller that does not suit your pump.

Sustituye el sello del extremo húmedo al mismo tiempo

When the impeller is replaced, the pump has to be opened up. For that reason we strongly suggest fitting a new wet end seal during the same job. A suitable option is the US Seal PS-1000 – wet end seal, which is sold separately from the impeller.

Doing both jobs together means the pump only needs to be dismantled once, rather than a second time when the old seal is later replaced.
