I have a Whisperflo pump that has a tag that says WFE-2, 1.90 service factor, .50 horsepower.  The Magnetek tag says its part 7-177449-03.  From looking at your replacement list these 2 don't seem to go together.  The pump appears to be .75HP although it does not say that anywhere on the tag.  Any insight?

The correct replacement motor for your Pentair WFE-2 is model B845. This is a full rated 1/2Hp motor with a service factor of 1.9. The total HP is .95. A 1/2Hp full rated pump is sometimes labeled a 3/4HP uprated pump. That is why you may run across both ratings.

We recommend replacing the seals when you replace the motor. The seal kit is part number GOKIT32. Use GOKIT32SALT if you have salt water.
