The 920 High Pressure Test Pump is a hand operated pressure pump designed to generate pressure from 95% vacuum to 20,000 kPa (3000 psi/200 bar). With a long lever, it just takes 40 seconds to reach this pressure.
It uses a high-quality screw press designed for fine pressure adjustment, with an adjustment resolution up to 10 Pa (0.1 mbar). A specially designed shut-off valve makes the pressure as stable as possible during calibration. A built-in gas-liquid isolator protects the pump from moisture and dirt to reduce the need for maintenance. The residual liquid in the pump introduced from devices under test will be pushed out and collected during pressure release.
Two hand-tight quick connectors installed on the pump allow easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches. The 920 is an ideal comparison test pump for pressure instruments calibration.
