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.
Hi i am looking for a replacement motor for a Whipserflo WFE-2 (Part# 7-177449-03). Same specs as the post from HothouseSpa. based on this thread looks like model B2845 is a replacement. In another thread i came across model number B2661 as a replacement. The B2845 is an exact match to the specs for the original motor (Part 7-177449-03). However under the details section, nither one is CA compliant. When i started a chat i was given B2981 as a replacment, but the specs are off. The B2981 a CA compliant mototr. Can someone calrify the dfferences between the 3 models?
B2845 is a single speed full rated 1/2 HP motor. The total HP rating is .95. (This would match an original WFE-2 Motor)
B2661 is a single speed full rated 3/4 HP motor. The total HP rating is 1.25.
