Product details

Waterway 310-3670 is the 2HP impeller assembly for the SVL56 high flow pump. It is the part that actually moves the water, and it is sized to the motor behind it.

Horsepower is not optional

Impellers are machined for one horsepower rating. The 2HP impeller is what a 2HP SVL56 was built with, and swapping in a different rating changes the flow and the load on the motor. Check the horsepower on the motor label before you order, not the label on the pump lid.

Symptoms of a worn impeller

A pump with a tired impeller still primes and still sounds normal, but the returns go soft and the filter pressure drops. Once you have ruled out a blocked basket, a dirty filter and a suction side air leak, the impeller is next: look for cracked or eroded vanes, and for hair and grit packed solid into the passages.

While you are in there

The impeller sits behind the shaft seal, so the seal has to be disturbed to get the impeller off. Most people order the seal with the impeller rather than doing the job twice.

Questions and answers

What people ask about this product, answered by our pool techs.

Which pump does this fit?
The Waterway SVL56 high flow pump, in the 2HP size.
Does the horsepower have to match?
Yes. An impeller is cut for a specific horsepower, so a 2HP impeller belongs behind a 2HP motor. Fitting a different rating changes the flow the pump was built around.
Is the shaft seal included?
No. The impeller assembly is sold on its own. The shaft seal is a separate part and is worth ordering at the same time, since the pump has to come apart either way.
How do I know the impeller is the problem?
If the pump primes and runs but pushes weak flow while the baskets and filter are clean, pull the impeller and look for cracked vanes or debris packed into the passages.
