Showing Questions of 5

I need approx 32 gpm at 1000rpm. what kind of horsepower would be needed to produce the max psi on this pump

A: At 32 gpm and 2500 psi, this pump would require 55 Hp electric /73 Hp industrial gas or diesel engine.

If I use this pump to drive a Hydraulic motor that is rated at 14 GPM, do I have to reduce the RPM on the pump to that flow? or is it alright to run at a higher flow rate to the motor?

A: The flow going to a motor should not exceed the ratings for that motor. Trying to push excessive amounts of oil through a unit designed for much less will destroy it in short order.

What is the foot pounds of torque required to operate this pump at 2000 rpm

A: We have no manufacturer data which details the torque required, unfortunately. Theoretically it calculates out to a 104 HP (electric) demand, or 274.3 ft/lbs torque at 2500 psi.

Can this pump be driven form a indirect V-Belt drive or does it need to have a direct drive?

A: These should be direct driven or used with a jackshaft if pulley driven to prevent side load on the shaft.

How much power is required to run this?

A: That depends on the RPM the pump is turned and what pressure you want to develop. As an example turning the pump 1800 RPM produces 55 GPM of flow. If you want to build 2500 PSI that would require about 95 HP.
