Showing Questions of 6

What size belt is the flywheel made for? A or B? I can't find that in the specs. Thanks Bill

A: This flywheel is for use with 1/2" A belts.

What is the recommended rpm speed of the motor used with this pump?

A: The motor speed is largely irrelevant as long as the correct pulley reduction is used to provide the pump with a flywheel rpm of no more than 800 rpm with 3 hp input, or no more than 1250 rpm with 5 hp input.

I'm assuming 20.35 cfm is the freeflow rating, do you know what it is at any specific pressure? (90psi, 150psi, or whatever)

A: This compressor is also rated 15.87 cfm @ 175 psi.

What model number is this? I am looking for model PMP22K28CH-E.

A: That is the information we have, but our model does not have the -E at the end.

Is this compressor noisy?

A: It can be noisier when run near its full rated rpm. It is quieter when run slower. We do not have any objective data to quantify the noise level.

Is this the same pump for Model CT580V282? Serial # W535026026. (C-AIR)

A: These are made by Chinook and we don not have info on C-Air to compare.
