Additel 901A Low Pressure Test Pump 

 

Description

Additel 901A Low Pressure Test Pump
Air : -6 psi to 6 psi

  • Portable, only 3.5 lb
  • Great stability and high resolution
  • Minimal maintenance
  • Hand-tight quick connectors

The 901A Low Pressure Test Pump is a hand operated pressure pump designed to generate pressures from -6 psi (-0.4 bar) to 6 psi (0.4 bar). A high-quality screw press is designed for fine pressure adjustment, with an adjustment resolution up to 0.1 Pa (0.001 mbar). The 901A is a very stable low pressure calibrator. It makes use of an isothermal bellows chamber which is designed for reducing the possible effects of environmental temperature change. Most pumps make use of a check valve (non-returning valve) and are not well insulated which will cause large fluctuations in pressure with a change in ambient temperature or when the unit is touched. The 901 does not use a check valve and is remarkably stable. 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 901A is an ideal comparison test pump for low pressure applications.

Features

  • Portable:
    Only 3.5 lb
  • Adjustment  Resolution
    0.1Pa (0.001 mbar); Specially designed screw press for fine pressure adjustment.
  • Great Stability
    Isothermal chamber: the pressure chamber is insulated to reduce the influence from environmental temperature changes.

    Specially designed bellows minimize leakage to guarantee excellent stability.
  • Durable and Minimal Maintenance
    Without non-returning valve that is usually used on 

    troublesome hand pump.
  • Easy-to-use
    Pressure could be set and adjusted precisely and quickly through a simple turn of the handle.
  • Hand-tight Quick Connectors
    Allows easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches.

Applications

The Additel 901A is designed for low pressure application requiring accurate low pressure testing and calibration. It can be used in calibrating low pressure gauges, transmitters, or other pressure measuring instruments.
