Find the right pump or motor

Enter what is printed on the label of the one you are replacing. Anything that differs is shown with the difference spelled out, so you can judge it for yourself.

Port size is the plumbing thread, not the pipe — a 2 inch union measures about 3 inches across the male thread. Amps are compared to within half an amp, since published figures round differently between motor brands. Voltage is never treated as a near miss: a 115V motor is not one step from a 230V supply. Anything whose page does not publish a figure you entered is left out rather than offered with a caveat — search it by name to see it anyway.
