The ADT937 Hydraulic Hand Pump is a version of the ADT936, with the only difference being the media type. The ADT936 is compatible with only oil whereas the ADT937 is compatible with phosphoric acid ester fluid and Skydrol oil.
The ADT937 is a hand operated pressure pump designed for calibrating pressure measuring instruments with phosphoric acid ester fluid and Skydrol oil in the range from 85% vacuum to 100,000 KPa (15,000 psi/1,000 bar). With 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. With no check valve (non-returning valve), the ADT937 avoids the troublesome leakage issues that are usually experienced with hand pumps and allows for minimal maintenance. 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 ADT937 is an ideal comparison test pump for calibrating pressure measuring instruments such as test gauges, indicators or transducers in the laboratory.
