Description

The Additel ADT 938 High Pressure Test Pump is specially designed for calibrating oil-free pressure measuring instruments in the range of -12.5psi (-0.85bar) to 15,000 psi (1000 bar). All parts used in the pump have been carefully cleaned to remove oil. The pump uses water as the media. With the patented screw press technology, high pressures can be easily generated, increased and decreased smoothly. A specially designed shut-off valve makes the pressure as stable as possible during calibration. Without the non-returning valve that is used on troublesome hand pumps, the ADT 938 requires minimal maintenance. Two hand-tight connectors installed on the pump allow easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches. The ADT 938 is an ideal comparison test pump for calibrating oil-free pressure measuring instruments such as test gauges, indicators or transducers in the laboratory.
