Benefits

Easy to Use

The Ralston DCAP-PV Pressure / Vacuum Hand 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.

Easy to Maintain

The fine adjust and bleed valve on the Ralston DCAP-PV Pressure / Vacuum Hand 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-PV Pressure / Vacuum Hand Pump is the clear choice.
