Application areas
Comparison 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 may be carried out in the laboratory, workshop, or on site at the measuring point.

Easy handling
For a precise approach to the measuring points, the comparison test pumps are fitted with a spindle for fine control. In particular, the smooth running of the hand spindle enables this, even at very high pressures. Furthermore, the spindles for this model range only run within the pump body. This eliminates an unfavourable bending moment on a spindle that has been unscrewed.

Especially for field operation there is the advantage that dimensions of these pumps do not alter during operation through the rotation of the spindle.
With the integrated priming pump, large test volumes can be easily filled and primed for both comparison test pumps.

Easy operation
If one connects the test item and a sufficiently accurate reference measuring instrument to the test pump, on actuating the pump, the same pressure will act on both 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.
