The new Additel ADT946A hydraulic hand pump is a benchtop pressure testing pump designed to generate high pressure to 100,000 kPa (1,000 bar). This pump incorporates a dual-piston system which is ideal for filling large volume workload with the hand pump and providing smooth increase and decrease of pressure with the high pressure, fine adjust screw press. The ADT946A test pump incorporates an isolation valve which isolates the calibration volume from the check valve associated with the hand pump. Because the check valve can often be a source of leaks and maintenance, the isolation valve provides more stable measurements and reduces potential maintenance of the pump. Three 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 ADT946A is an ideal comparison test pump for calibrating pressure measuring instruments such as test gauges, indicators or transducers.

Hand pump to fill large volume systems

Durable and Minimal Maintenance

Isolation valve provides stable pressures while
reducing maintenance on the hand pump check valve.


15,000 psi (1,000 bar) can be generated easily with
the dual-piston system.

Three hand-tight quick connectors

Allows easy connection and disconnection to the test
pump without the need for PTFE tape or wrenches.
