Kellogg American 1970, pump model G201 XC, two cylinder single stage. (Bore 2-1/4, Stroke 2-1/4)

I just finished restoring this pump and have mounted on its original 35 gal, max 165 psi tank.


This air compressor didn't have a motor when I got it. What would you recommend the hp and rpm's be for an electric motor for this pump?

2-3 inch pulley it is.

motor speed
by: Doug in s.d.ca

The pump may be able to take it, but I suspect not very efficiently.

Based on what Dave said, you'd want to reduce the belt speed by half, IOW, reduce the circumference of the motor pulley by half:

(pi)d=circumference

3.14 * 5 = 15.7...15.7 * .5 = 7.85 desired (x)

3.14 * x = 7.85

x = 7.85 / 3.14

x = 2.5

So, Maybe a 2 or 3 inch drive pulley for the higher speed motor.

2 hp RPM's?
by: MIckey C

Northern Tool has a 2hp Leeson, but not in 1750, only 3450 rpm's. I've been told Kellogg's are made tough so I figure 3450 rpm's won't be to hard on the pump.

You will need a 1.5hp or a 2hp motor 1750 rpm and a 5 inch motor pulley

Sure.

Do you have specs on the pump?

Generally they come with a hp and rpm rating.

I'm not having any luck finding that particular unit.

Pumps in good shape replaced all gaskets, valve assembly and rings. I'd like to get as much air as possible without overloading the pump.

Depends on the pump and how much air you want...
