The pneumatic pressure pump Sika P4 is used to check, adjust or calibrate pressure equipment of all kinds. It was specially developed for low pressures of up to 4 bar. The generation of negative pressure is also possible, but very dependent on the volume of the test room. Due to its low weight and compact design, the pneumatic pressure pump can be directly on site at the test object be used. When using the pressure pump, it is necessary to connect a reference pressure gauge and the connection. Testing, adjustment and calibration of pressure gauges of all types • Long-term stable measurements without pressure loss due to hermetically sealed vacuum chamber • Exact adjustment in the mbar range thanks to ultra-fine thread pitch and large-volume regulating valve • Tool-free change between overpressure and vacuum generation • Smallest mobile hand test pump on the market.
