The WIKA CPP7-H pneumatic hand pump is specifically designed for testing, adjustment and calibration of low-pressure measuring instruments. With a pressure range of -0.85 bar to +7 bar, it generates smooth, controllable positive and negative pressures via a switchable valve, while the integrated fine-adjustment valve enables precise setting down to the mbar range — ideal for sensitive low-pressure transmitters, switches, and gauges.

Constructed with an anodized aluminum body, brass internal components, and ABS housing with NBR seals, the CPP7-H operates on ambient air only — no lubrication or external power source is required. Its compact, lightweight design makes it easy to carry between job sites. Applications span HVAC commissioning, clean room pressure verification, medical gas systems, and filtration/dust extraction monitoring where accurate low-pressure measurement is critical.

Standard delivery includes the CPP7-H hand pump, a T-connector, two 0.5 m connecting hoses, four hose connection adapters, a selectable connection adapter (G 1/2, G 1/4, 1/2 NPT, or 1/4 NPT), and a roll of PTFE sealing tape.
