The Additel ADT 925 high pressure test pump is a hand-operated hydraulic pressure pump designed to generate pressure from -12.5psi (-0.85bar) to 6000psi (400bar). With the patented screw press technology, the high pressure can be easily generated, increased and decreased smoothly. Without the non-returning valve that is usually used on troublesome hand pumps, the ADT 925 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 925 is an ideal comparison test pump for calibrating pressure-measuring instruments such as test gauges, indicators or transducers in the field or laboratory.
