It is necessary to have two essential information: the reservoir capacity and the required cylinder extension speed. These data, combined with the characteristics of the cylinder or tool to be operated, together with the type of application, are essential to ensure the correct functioning of the entire system.
Reservoir capacity: After having selected the cylinder/tool to be operated and determined the oil volume required for the stroke, it is good practice to consider a 20% margin, not forgetting to add an additional 32 cm³ for each linear meter of DN6 hydraulic hose used. For double-acting cylinders, subtract the return volume (which flows to the reservoir during extension) from the volume required for full advancement, also in this case consider a 20% margin.
- Single-stage pumps (PN13#, PNP13#, PS1####): for small tonnage cylinders or short strokes.
- Two-stage pumps (PN14#): for medium tonnage cylinders and medium-long strokes, excellent compromise between cost and performance.
- Two-stage pumps (PN16#): ideal for high tonnage cylinders and long strokes, maximum performance.
- Two-stage pumps (PN26#): suitable for most double-acting cylinders (pay attention to the oil volume required).
Choosing the right pump means ensuring safety, efficiency and performance. The pump selection tables provide an essential reference to avoid overloads and maximize the life of the system.
