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 CPP4000-X comparison test pump is a hydraulic
comparison test pump for generating pressure up to
4,000 bar. It is technically identical to the instrument base of
the model CPB3800HP dead-weight tester. The integrated
dual-area spindle pump with switching valves enables rapid
lling of the test system and smooth pressure generation.
Comparison test pump model CPP4000-X
At the same time, the precisely adjustable spindle pump also
serves for ne pressure 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 with double ended metal cone. Two
threaded adapters mounted on M16 x 1.5 male thread are
included in the scope of delivery. Further thread adapters
are available for the calibration of instruments with dierent
connection threads.
Compact instrument design
The CPP4000-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 case and the low weight associated with these, the
CPP4000-X is also well suited for on-site applications.
