Step 1: Select the hydraulic cylinder that best suits the application.
Step 2: Select the series of hydraulic pump with adequate oil output and reservoir capacity to power cylinder. See page 184. Check speed/selection chart on page 178.
Step 3: Select pump within series with the valve option that is best suited to the cylinder and application. See pages 190-191.
Hydraulic Pump Considerations
What maximum system operating pressure (psi) is required?
What volume of oil delivery is required? (For manual pumps, cu. in. of oil per handle stroke; for powered pumps, cu. in./min. of oil).
Is a single- or 2-speed pump required? (2-speed pumps deliver high oil volume at low pressure for rapid cylinder piston advance, then shift to to the high pressure, low volume stage under load).
What is the preferred source of power?
a) Manual (hand or foot operated). Provides portability, can be used where electricity or shop air are not available.
b) Air/Hydraulic. Uses shop air or a portable air compressor.
c) Electric /Hydraulic. What voltage is available? Is a battery operated pump preferred?
d) Gasoline Engine/Hydraulic. Powers high-output pumps at remote job sites where air or electricity are unavailable.
Is portability of the pump a factor to consider?
Will the pump be used intermittently, or will it need to provide high-cycle operation? Does the application require that the pump be capable of starting under load?
Is fluid heat build-up a factor in your application? High cycle applications may require a larger capacity oil reservoir for cooling. Also, if you are using large displacement cylinders, the reservoir capacity must be sufficient to fully extend the piston of the cylinder.
Will the application require large displacement or multiple cylinders? Reservoir size and pump output levels will be factors to consider.
Does the working environment require a pump having a low operating noise (dBA) level?
