A versatile, easy-to-use pressure pump that allows you to quickly switch to vacuum testing with just a turn of a knob, Pneumatic Pressure and Vacuum Scissor Hand Pump (DCAP-PV) is ideal for calibrating DP pressure transmitters, testing pressure switches or checking pressure gauges in the field.
Ralston Pneumatic Pressure/Vacuum Hand Pumps come in a variety of different configurations. Choose which bundle is right for your application.
The Ralston DCAP Pressure/Vacuum Test Pump has larger displacement than similar products on the market, which allows you to rapidly build pressure with fewer pump strokes. And unlike the competition, it allows you to quickly and easily change from pressure to vacuum using a knob instead of requiring an additional tool. There's no need for a spring tension adjustment - the vacuum is generated on the squeeze stroke, rather than the spring-loaded return stroke. This allows our spring to be less stiff, making pumping much easier for the user.
The fine adjust and bleed valve on the DCAP Pressure/Vacuum Pump are separate, allowing for ease of maintenance. And the device is field maintainable with simple tools found in any toolbox.
For field calibration operations that require both pressure and vacuum, the dependable, easy-to-use Ralston DCAP Pressure/Vacuum Pump is the clear choice.
