Wika CPP700-H Hydraulic Hand Test Pump
Test pumps serve as pressure generators for the testing, adjustment and calibration of mechanical and electronic pressure measuring instruments through comparative measurements.
These pressure tests can be carried out statically in the laboratory or workshop, or on-site at the measuring point. The model CPP700-H and CPP1000-H hand test pumps have been developed specifically for on-site pressure generation.
If one connects the test item and a sufficiently-accurate reference pressure measuring instruments to the test pump, on actuating the 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.
The CPP700-H and CPP1000-H hand test pumps, despite their very compact dimensions, enable simple and accurate pressure generation of up to a max. of 700 bar or 1,000 bar / 10,000 psi or 14,500 psi (respectively), with an integrated switching from system pressure to high-pressure generation.
For the precise setting for accurate comparative testing, the pump features a fine-adjustment valve.
As a pressure-transmission medium, either hydraulic oil or clean water, free of calcium-carbonate should be used.
The reference instrument is screwed directly to the top of the pump, and the test item is connected using a connecting hose with a G ¼ female thread, included in delivery. The CPP700-H is supplied, as standard, with a Minimess® 1620, test item connecting system.
