Hydraulic Intensifier 7250 psi max

APPLICATION: The hydraulic intensifier a low pressure (displacement of the cylinders),
converts a hydraulic pressure on the primary with increasing counterpressure the
side (input) into a higher pressure on the intensifier switches automatically to pressure
secondary side (output). intensification. For unclamping, the cylinder is
directly controlled with the low-pressure of the

DV is controlled via port R and thereby free
return through the intensifier is guaranteed.
IMPORTANT NOTES: The hydraulic oil must
be perfectly filtered with particles not larger than
nominally 10 micron. This is the reason why
we offer a filter unit (part no. CLR-3887-087),
which can be directly integrated in the tubing
of the low-pressure side. If the intensifier will
be used on uncoupled systems (no connection
to the pressure generator) a pilot-controlled
check valve should be mounted at the high-
pressure side (consider min. control pressure
for opening). For pilot-operated check valve,
see valves section.
When designing an installation, pay attention
that there can be leakage between the ports IN
and R of the high-pressure intensifier.
Leakage rate approx. 50 cm3/min. When
using the intensifier in uncoupled systems
there will be a pressure increase in the
unclamping line due to the leakage. — Please
