The Additel ADT928AC-B2 Hydraulic Pressure Test Pump is a hand operated pressure pump designed to generate pressure up to 15,000 psi (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 fine adjustment. The Additel ADT928AC-B2 features an 1/2 BSP female pressure port and is designed for use with phosphoric acid ester fluid and Skydrol oil media.

The Additel ADT928AC-B2 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. Two 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 Additel ADT928AC-B2 is an ideal comparison test pump for calibrating pressure measuring instruments such as test gauges, indicators, or transducers in the field or laboratory.
