The Additel ADT 927 High Pressure Test Pump is a hand operated hydraulic pressure pump designed to generate pressure from -12.5psi (-0.85bar) to 10,000 psi (700bar). With the patented screw press technology, high pressures can be easily generated, increased and decreased smoothly. Without non-returning valve that is usually used on troublesome hand pumps, the ADT 927 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 ADT927 is an ideal comparison test pump for calibrating pressure measuring instruments such as test gauges, indicators or transducers in the field or laboratory.
