help with pump selection

help with pump selection

help with pump selection

(OP)
I'm going to use a hydraulic motor to move a conveyor. I've selected one based on torque and speed that it's needed. The specs are as follows:

speed: 279 RPM
flow l/min 265
torque: 3440
pressure: 260 psi

What I need to know is how do I know what wha kind of pump to use, and how to select the correct one to pair with the motor.

I'd appreciate any help . Thanks a lot.

RE: help with pump selection

What type of motor is that? It has a very low pressure rating and very high flow. A pump that produces that sort of flow will be quite a lot larger than what you actually require if you go up in pressure and down in flow.

(you can't escape me)

RE: help with pump selection

Why not just contact a hydraulic motor / pump supplier and save yourself and others all the problems associated with such a simple request.

Eaton 10,000 series disc valve motor. I selected it because it works at low speed with very hight torque. But dont know much abot the pressure and flow issue. Im starting from scratch so I thought I should select the motor and then go backwards to the pump and so on...

Im absolutely going to do that. But this is part of a college project so I need to justify my selection.

RE: help with pump selection

College project? Homework questions are frowned upon here.

RE: help with pump selection

Use a gear motor (hydraulic power unit) with a pressure-compensated pump set to deliver the required pressure and a proportional valve to control the output from the gear motor.

What Artisi said.

RE: help with pump selection

As a (now ex) trainer I would be happy to see the thought and work put into a project to establish what is needed, why and what you intend doing about it. Making contact with a supplier with all relative, correct data, presented logically would always win points from me, more so than running around in circles getting nowhere. Alternately request the necessary tech data / brochures etc from a supplier and attempt your own selection.

RE: help with pump selection

We are pump supplier. basically, need to know your motor type and shaft size and use this pump for what? etc.
For more info. can contact via by e-mail.
