The WIKA CPP10-H pneumatic hand test pump is designed to generate pressure and vacuum for testing, adjusting, and calibrating pressure measuring instruments. It delivers pressure up to 10 bar and vacuum down to -0.85 bar, with precise pressure control via a built-in fine adjustment valve. Suitable for use in laboratories, workshops, and on-site field applications, it features a switchable valve for fast, seamless changes between pressure and vacuum generation. The CPP10-H can be easily connected to test circuits via the included T-connector and adapters.

Beyond calibration, the CPP10-H is an effective tool for pneumatic leak testing. Operators can pressurize a test circuit, isolate it via the fine-adjustment valve, and monitor for pressure decay to identify leaks in fittings, seals, and small vessels — a common requirement in HVAC commissioning, cleanroom validation, and medical gas system maintenance.

The unit operates using ambient air only, with no lubrication required, making it purpose-built for low-pressure calibration and leak test applications. It features a compact, lightweight design, constructed with anodized aluminum, brass, ABS housing, and NBR seals for long-term durability. It is optimized for operation at an optimal temperature of 64 to 82°F, and can function reliably in ambient conditions ranging from 14 to 122°F.
