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? |
