The 920 High Pressure Test Pump is a hand operated pressure pump 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 is an ideal comparison test pump for pressure instruments calibration.
Features
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.

Hydrostatic calibration pump for use with water
Is there a hand operated hydrostatic calibration pump as per the ADT920, but for operating using water as the test medium rather than air?
We would suggest the PGS700 which is a hand-held hydraulic pump that can be used with water…
…or the ADT925 which is a bench based hydraulic screw-press pump that can also be used with water.
