Description
Application areas
Test pumps serve as pressure generators for the testing,
adjustment and calibration of mechanical and electronic
pressure measuring instruments through comparative
measurements. These units can be used in the laboratory or
workshop, or on site at the measuring point.
Easy operation
By connecting the test item and a suciently accurate
reference pressure measuring instrument to the test pump,
the same pressure will act on both measuring instruments. By
comparison of the two measured values at any given pressure
value, a check of the accuracy and/or adjustment of the
pressure measuring instrument under test can be carried out.
Easy handling
The model CPP1200-X comparison test pump is a hydraulic
comparison test pump for generating pressure up to 1,200 bar.
It is technically identical to the instrument base of the model
CPB3800 pressure balance. The integrated dual-area spindle
Comparison test pump CPP1200-X
pump with switching valves enables rapid lling of the test
system and smooth pressure generation.
At the same time, the precisely adjustable spindle pump also
serves for pressure ne adjustment. A control schematic for
pressure generation on the instrument base facilitates quick
and easy operation.
The two test connections are equipped with G ½ female
loose union connections. Corresponding thread adapters
are available for the calibration of instruments with dierent
connection threads.
Compact instrument design
The CPP1200-X is also particularly notable for its compact
dimensions, which are not altered during operation, since the
spindle runs within the pump body.
With those dimensions, the exceptionally robust ABS plastic
housing and the low weight associated with these, the
CPP1200-X is also particularly suited for on-site applications.
