Cylinder Pump

The CylinderPump is an ideal pressure source for calibration of low pressure differential transmitters. It works like a bicycle pump, but with a fine adjustment piston that makes it easy to set the pressure very precisely. On the side of the pump is a vent valve, designed for precise control, so you can open it very slowly and easily control the rate of change of pressure. Another valve changes the cylinder hand-pump into a vacuum pump, expanding the usefulness of the pump. This is an all metal pump and is field rebuild-able.
