Taco standard E design seal kit for FE series pumps. Must have complete model number to verify this is the correct seal kit. This seal kit fits many models of Taco pumps. The model number is the key to the correct selection. The following is an example of a Taco model number: BM5008-7.9-C2B2. The first two letters (BM) are the series, the next two numbers (50) are the flange size, the next two numbers (08) are the nominal impeller diameter, followed by a dash and a number (-7.9), which is the actual diameter of the impeller trimmed to meet a specific flow, followed by another dash and letter/number combination (-C2), which is the frame size and style, and finally the last letter/number combination (B2) is a packing or seal design.
