The 920 and 920HV High Pressure Test Pumps are hand operated pressure pumps designed to generate pressure from 95% vacuum to 3,000psi (200bar). With a long lever, it just takes 40 seconds to reach 3,000 psi (200 bar). A high-quality screw press is 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 and 920HV are ideal comparison test pumps for pressure instrument calibrations.

High Efficiency
Generate 3,000 psi (200 bar) in 40 seconds.

Adjustment Resolution
0.001 psi (10 Pa, 0.1 mbar).
High-quality screw press for fine pressure adjustment.

Great Stability
A specially designed shut-off valve makes the
pressure as stable as possible during calibration.

Durable and Minimal Maintenance
Built-in gas-liquid isolator protects the pump from
moisture and dirt.
The residual liquid in the pump introduced from
devices under test will be collected and then pushed
out and collected during pressure release.
Anticorrosive and wear resistant material are used to
improve the reliability further.

Hand-tight Quick Connectors
Allows easy connecting and disconnecting to the test
pump without the need for PTFE tape or wrenches.
