Ralston Instruments DCAP calibration test pump

The DCAP pneumatic hand pump from Ralston Instruments is specifically designed for use in pressure calibration and test applications in the oil and gas, petrochemical, maritime, pharmaceutical and aerospace industries.

Existing hand pumps are hard to pump at high pressure and require routine servicing. Unfortunately, parts are often inaccessible and the pumps are difficult to repair. To answer these challenges, the DCAP pump has been designed to reach 650 psi or 45 bar with less effort. The pump handles are constructed from anodised aluminium that won’t stretch or corrode. Hand fatigue is also reduced by using a pumping mechanism that increases pumping force with minimal effort.

Ease of repair was solved by ensuring that the pump can be serviced using simple tools found in almost any toolbox. All of the pump parts, including the main body, are easily replaceable and a simple repair kit will take care of any seals and wear items in the pump. In addition, all wearing parts are made of stainless steel or anodised aluminium to prevent corrosion and extend life.

Another issue with existing pumps is leakage over time. In many cases, this can actually be attributed to the hoses and fittings used in conjunction with the pump. The DCAP pump connects seamlessly to Ralston’s existing Quick-test hoses and adapters to reduce or eliminate leaks that are an issue in other hand pumps with standard threaded fittings. A QT hose and process fittings are included with every pump.
