Choosing A Cylinder

What push or pull tonnage is required
per cylinder in your application?
What is the push or pull stroke length required? Does the cylinder need to push or pull? Or both?
Does the application require multiple cylinders? Is the application stationary or must the components be light in weight for easy portability? Do you need to extend a rod or cable
through the center of the cylinder for the application as in a tensioning operation?
Does the application require that the
cylinder fit within limited clearance
work areas?
Does the application require that the
cylinder be "Dead-ended" at the end of its work stroke?
Will the cylinder need to withstand
off-center loads? Cylinders with swivel caps are available.
Does the application require that the
lifted load be supported for extended
periods?
Is corrosion resistance required? Will the application involve high cylinders
(over 2,500 in the cylinder's lifetime)?

Hydraulic Pump Considerations

What maximum system operating
pressure (psi) is required?
What volume of oil delivery is required? Is a single - or 2-speed pump required?
What is the preferred source of power?
Manual, Air/Hydraulic or Electric/Hydraulic, Gasoline Engine/Hydraulic

Manually Operated Pump

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?
Is portability of the pump a factor to
consider?
Must the pump operate in a spark-free
environment?
