Quick overview
- Matched to 2HP Impellers are cut for a horsepower rating, and this is the 2HP part for the SVL56.
- Fits the SVL56 The impeller used in the Waterway SVL56 high flow pump.
- Supplied as an assembly Sold as the impeller assembly rather than a bare vane.
- Restores flow A worn or packed impeller is the usual reason a pump runs but moves very little water.
- Order by number Waterway part 310-3670 pins down both the pump family and the horsepower.
- Plan on a seal at the same time The shaft seal has to come apart to reach the impeller, so most techs replace both in one visit.

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.
