Additel ADT 927 10000 PSIG Oil/Water Hydraulic Pressure Calibration Pump

The Additel ADT 927 hydraulic pressure calibration test pump is a hand operated pressure pump designed to generate pressures from -12.5 psi (-0.85 bar) to 10000 psi (+700 bar). With the patented screw press technology, the high pressure can be easily generated, increased and decreased smoothly. Without non-returning valve that is usually used on troublesome hand pumps, the ADT927 requires minimal maintenance. Two hand-tight connectors installed on the pump allow easy connecting and disconnecting to the test pump without the need for thread tape or wrenches. The ADT927 is an ideal comparison test pump for calibrating pressure measuring instruments such as test gauges, indicators or transducers in the field or laboratory.
