Which hand pump fits to which hydraulic cylinder?
The appropriate hand pump model basically depends
on the oil volume of the selected hydraulic cylinders.
To assist you in your choice please find proposals for
the most common cylinders in our range.
How to find the right hand pump in the following
charts?
The chosen hydraulic cylinder can be found in the
first column.
Several hydraulic cylinders connected to one hand
pump:
In those cases where several hydraulic cylinders are connected
to one hand pump, the oil volume must be multiplied by the
number of connected cylinders. The reservoir of the hand
pump must be at least equal to the required total oil volume
(plus reserve). If the reserve is very small it may be necessary
to top up the reservoir after the air bleeding procedure,
depending on the length of the hydraulic hose. During further
operation there is no need to consider the volume of the
connected hydraulic hose (regardless of the length) because
hoses always remain filled.
Double-acting systems:
Please note that while advancing a double-acting cylinder
about 1/3 of the cylinder?s oil volume flows back to the
reservoir (coming from piston chamber). After the air-bleeding
procedure both oil chambers will remain filled. |
