YX2003 Desk-top Hydraulic Pressure Calibration Pump can cope with various Pressure transmitting media (water, alcohol, aviation hydraulic oil, edible oil, etc.), which greatly expands the application range of liquid pressure sources. XY2003 desk-top hydraulic pressure calibration pumps adopt rigid pressure modules, which save time and effort, and the core seal is all rigid seal to prevent leakage. The maximum pressure can reach 250Mpa, and it is made of high-quality imported stainless steel, advanced foreign sealing technology, and refined through various processing techniques. The pressure source completely adopts an open structure, which is more convenient for maintenance; the screw type buck-boost, the buck-boost is stable, the pressure can be stabilized in an instant, and the return verification is very easy to operate; suitable for food hygiene, aerospace, military industry, metallurgy, metering, And other industries provide a stable, fast, safe and reliable ultra-high pressure source when calibrating pressure transmitters, pressure sensors, precision (ordinary) pressure gauges, and other pressure instruments.
