Additel ADT 938 -12.5 psi to 15,000 psi
Hydraulic Pressure Calibration Pump (oil-free)

  • Minimal maintenance
  • High Pressure: Generates pressure up to 15,000 psi (1000 bar)
  • Durable and Minimal Maintenance: Patented screw press technology, with no check valve (non-returning valve) inside that is usually used on troublesome hand pumps.
  • Easy-to-use: With the patented screw press technology, high pressures can be generated easily, increased and decreased smoothly
  • Extremely Low Leakage: Patented screw press technology, instead of leaking, troublesome check valve (non-returning valve) in hand pump.
  • Hand-tight Quick Connectors: Allows easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches.

The Additel ADT 938 Hydraulic High Pressure Test Pump is specially designed for calibrating oil-free pressure measuring instruments in the range of -12.5psi (-0.85bar) to 15,000 psi (1000 bar). All parts used in the pump have been carefully cleaned to remove oil. The pump uses water as the media. With the patented screw press technology, high pressures can be easily generated, increased and decreased smoothly. A specially designed shut-off valve makes the pressure as stable as possible during calibration. With no check valve (non-returning valve), the Additel ADT938 avoids the troublesome leakage issues that is usually experienced with hand pumps and allows for 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 Additel ADT 938 is an ideal comparison test pump for calibrating oil-free pressure measuring instruments such as test gauges, indicators or transducers in the laboratory.

The Additel ADT-938 is specially designed for calibrating oil-free pressure measuring instrument in the range from 85% vacuum to 15,000 psi (1000 bar). The Additel ADT938 can be used in calibrating oil-free pressure gauges, transmitters, or other pressure measuring instruments in aerospace, pharmaceutical, or food industries.
