Dwyer Calibration Pumps

Dwyer Calibration Pumps

When calibrating pressure transducers on a bench, actual pressure needs to be generated so that the pressure transducer / transmitter and the pressure calibrator can be connected in a manifold arrangement to see the pressure. For that purpose are hand operated Pressure Test Pumps.

• Pneumatic models use air and typically range from vacuum to about 600 psig.
• Hydraulic Test Pumps use oil and achieve much higher pressures of up to 10,000 psig

There are overlapping ranges, so select a model that best covers your applications.

Features to consider when selecting pressure calibration pumps

• Kit versions include hoses, fittings, spare filters, and/ or more than one pump to cover wider range at a savings
• Mult-iturn knob for fine adjustment of pressure
• Adjustable stroke control to allow for fast priming or filling of test systems. This gives the operator the ability to switch as needed to a smaller stroke for easier pumping at high pressure
• Pump can be easily cleaned without disassembly
