Dual Volume Handpump

 


The lever action hand pump, which is supplied with both the type T & R hydraulic deadweight testers, incorporates a dual volume control valve. This allows the pump to deliver a high volume in order to rapidly fill systems and build pressure. The low volume permits easy pumping at high pressures and a more gradual approach to the point of pressure calibration. A vernier adjustment is provided for fine adjustment to the desired pressure.
