Additel 938 Oil Free Pressure Pump

The ADT938 Hydraulic High Pressure Test Pump is a hand operated pressure pump designed to generate pressure from 85 % vacuum to 1000 bar or 15,000 psi using water.
With the patented screw press technology, high pressures can be easily generated, as well as increased and decreased smoothly.

A specially designed shut-off valve makes the pressure as stable as possible during calibration. With no check valve (non-returning valve), the 938 avoids the troublesome leakage issues that is usually experienced with hand pumps and allows for minimal maintenance.

Three 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 ADT938 is an ideal comparison test pump for calibrating pressure measuring instruments such as test gauges, indicators or transducers where an oil free medium is required.
