Is there a way to find out what the design speed of a pump is? I have a Fiac pump with pulley wheels and want to ensure I get the correct motor as I do not want to overspeed the pump.
Thats the point. I want to know the ideal speed of the pump so that I can match a motor and pulley. The two pulleys that came with the pump are 165mm and 350 mm dia which equates to a pump speed of 1320 rpm. What I need to know is if that speed of pump is the speed it was designed to run at to enable the cooling/oiling to operate as designed.
on a 1425rpm motor, with the 165 pulley on the motor and the 350 pulley on the pump, the pump will be rotating at 672 RPM,
on a 2850 motor the pump would be doing 1344 RPM
depends what the pump is intended to run at and if the supplied pulleys were intended to be fitted to your pump.
I think you need to establish what the manufacturers RPM spec for the pump is, then see if the pullys are going to give you that speed.

on the fiac site what pumps are listed are running at all sorts of Diff speeds,3150,1350,1035,1400,1095,1250.
Ford34/2, that is what I am asking, what is the recommended speed of the particular pump that I have got. Its a Fiac pump , I am told it is a 14cfm unit and the pulleys, I think ,are the original ones. I got it from an auction and it came with the safety cage and belt. The motor has been found to be dead. Hence I need to ensure I get the correct motor.
sticking my neck out, but I think if you say this is a 14 cu Ft pump then, 500-700 RPM might well be right, but sadly this is a gut feeling and not based on any manufacturers data. Fiac pumps may well be totally different to Ingersoll Rand.
It may be possible to establish if the knackered motor is 2 pole or 4 pole, by pulling it to bits, but I realy dont know. Maybe an Electrician member can help.
