ADT 938 High Pressure Hydraulic Hand Pump

November 01, 2019




The ADT 938 Hydraulic High Pressure Test Pump is specifically designed for calibrating oil-free pressure measuring instruments in the range of -85 kPa to 100,000 kPa. All parts used in the pump have been cleaned to remove any oil. A high quality vernier control allows the high pressure to be easily generated and controlled smoothly. Two hand tight connectors installed on the pump allow for easy connecting and disconnecting to the test pump without the need for wrenches or thread tape. The ADT 938 is an ideal comparison test pump for calibrating oil-free pressure instruments in the workshop.
