Water pumps have several parameters you need to consider
Inlet and outlet.. Normally 1/2 inch IPT but plastic.. Most all are the same, Optional is a barbed connector but they make adapters that go to 1/2 inch.
Pressure.... When I replaced my 45 PSI I went with a 55 PSI.. Keep it 55 PSI or less
GPM.. I went from 2 to 2.5 when I upgraded
Mounting.. 4 Screws into the wood base,, Need not be identical
POWER.. Ok, so it draws a bit more.. NOTE Water pump controllers come in two types. One is electronic and the higher power may burn it out, Mine is switches.
The moral: Do not worry about "Same part number identical replacement) get one that has at least the GPM capacity and is 55 PSI or less and you will be very happy.. Mine cost me $0.00 after Swag Buck gift cards discount.
