Additel ADT927W-B Hydraulic Pressure Test Pump


Hydraulic Pressure Test Pump, for Use with Water, to +700 bar (10,000 psi), 1/4″ BSP

  • Portable, only 7 lb
  • Minimal maintenance
  • Increase and decrease pressure smoothly
  • Hand-tight quick connectors


The 927 Hydraulic Pressure Test Pump is a hand operated pressure pump designed to generate pressure from 85% vacuum to 10,000 psi (700bar). With the patented screw press technology, high pressures can be easily generated, as well as increased and decreased smoothly. With no check valve (non-returning valve), the 927 avoids the troublesome leakage issues that is usually experienced with most hand pumps and allows for minimal maintenance. 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 927 is an ideal comparison test pump for calibrating pressure measuring instruments such as test gauges, indicators or transducers in the field or laboratory.
