Sump Pump Selection

[ER_Azza]

Hi All

Need a a bit of help. Not my speciality in pump.

Has an old sump pump, pumping water on a 2" pipe to a header - check valve before entry to the 8" header (about 5 meter high). Pump is running at 1460rpm. Pump head is 20m.

Looking to buy a spare and the only one proposed/available by the vendor is one driving at 2930rpm with a pump head of 40m.

SAME flowrate.

What's your thought?

Replace the old pump and replace with new. The old (how old?) has already probably reached its service life.
Now, start with new pump that you can be sure of.
