Wika Mensor’s CPP1000-M Hydraulic Hand Spindle Pump is designed with a 14,500 psi pressure range and 110 cm³ reservoir. The pump is essential in applications involving the testing, adjustment and calibration of mechanical and electronic pressure measuring instruments through comparative measurements. By connecting 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. Through 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 executed.
