Additel ADT928-N Hydraulic Pressure Test Pump


Hydraulic Pressure Test Pump, 0 to 15000 psi (0 to 1000 bar), 1/4NPT F

  • Pressurize large-volume workload
  • Generate to 15,000 psi (1,000 bar) pressure
  • Portable only 8.6 Ibs (3.9kg)
  • Increase and decrease pressure smoothly
  • Hand-tight quick connectors


The Additel 928 Hydraulic Pressure Test Pump is a hand operated pressure pump designed to generate pressure to 15,000 psi (1,000bar). 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 928 Test hand 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 928 is an ideal comparison test pump for calibrating pressure measuring instruments such as test gauges, indicators or transducers in the field or laboratory.
