Comparator Pump High Pressure - 7000 Bar Hydraulic Oil

Bench Mounted High Pressure Hydraulic Oil Comparator for calibration pressures up to 7000 Bar / 100 000 PSI. The HIgh Pressure Comparator comprises a priming pump (located on the side of the unit) and oil reservoir to generate the initial pressure system. Ultra high pressure is generated from a secondary screw pump (located on the front of the unit).The reference instrument and device under test are mounted at the top of the unit. Bench mounted comparator pumps provide a stable source of pressure when calibrating pressure gauges or pressure transmitters against a known reference source such as a 0.25% accuracy bourdon tube test gauge or precision pressure transmitter.
