3-step plan for composing a hydraulic cylinder system

Step 1

Select one or more cylinders.


  • What is the weight of the load to be lifted?

  • What is the total recommended cylinder capacity?

  • With how many cylinders must/can the load be lifted?

  • What capacity for each cylinder is required then?

  • What is the required stroke length of the cylinder?

  • What is the required closed height (overall dimensions) of the cylinder?

  • How must the plunger return; gravity, spring or hydraulic?

  • Is lifting in one or more steps possible?

Step 2

Select the proper pump.


  • Select from hand, foot, pneumatically, electrically, petrol or diesel driven pumps.

  • Hand / foot pumps: with a double-acting cylinder (hydraulic return), mount a double-acting valve on your hand pump (only possible with PA *8 models).

  • Vari pumps: dependent on whether you use a single- or double-acting cylinder, mount a single-acting or doubleacting valve on the Vari pump.

  • What minimum tank volume of the pump is required?

  • Select a pump output corresponding with the required operating speed.

Step 3

Select the accessories you need.


  • Choose the correct number of hoses that you need and the required length. Take the required (safe) distance between cylinders and operation (pump and/or valve block) into account.

  • When the system contains several cylinders controlled by one pump, we recommend you to install a FlowPanel between the cylinders and the pump for accurate control of the oil flow to the cylinders.

  • Select any necessary couplers, pressure gauges, valves and/or assembly material.

Lock Nut Hydraulic Jack enables you configure your high-pressure hydraulic system quickly and easily. Cylinders, pumps, valve blocks and/or hoses. The configurator gives you a step-by-step guide for the selection of the components that are required for your hydraulic system.
