Hand test pumps / Pressure range up to 4 bar

簡介

Type P4

  • Testing, adjustment and calibration of all types of pressure gauges
  • long-term stable measurements without pressure drop due to hermetically sealed vacuum chamber
  • exact setting in the mbar range thanks to ultra-fine thread pitch and large-volume regulating valve
  • tool-free changeover between overpressure and vacuum generation
  • smallest mobile hand test pump on the market

Practical

The test pumps and pressure generators are developed so that all pressure systems to be tested can be adapted directly. The DUT is simply connected via the robust, industrial pressure hose with quick coupling and the adapters supplied. The reference sensor is mounted directly on the top of the pump using a positioning adapter.

The desired test pressure is first generated by means of the handles and then precisely adjusted with the fine adjustment valve. Thus, the same pressure level is present at both instruments. The pressure relief valve allows a stepless pressure reduction and ensures a precise and easy test run even when the pressure drops.

At the most basic level, the pressure is indicated by an analogue pressure gauge. In addition, easy-to-read digital pressure gauges or hand-held instruments can be used. By comparing the display value of the reference sensor and the measured value of the DUT, it is possible to check the accuracy or adjust the pressure gauge to be tested.

Mobile and independent

SIKA test pumps and pressure generators are ideally suited for mobile use. The low weight and compact design allow easy transport directly to the measuring point. The instruments are immediately ready for use and work without additional supply voltage. It is not necessary to carry nitrogen cylinders along or to connect to a compressed air network. The wear-free pressure generation is simple and smooth, regardless of ambient temperature and orientation by manual operation.

Basic and Solid version

The basic equipment of the Basic version of each test pump includes a suitable pressure hose. The hydraulic hoses are equipped with a self-sealing quick coupling. In the solid version, inch, conical or metric adapters are available for all common connection threads. The matching seal kit is also included in the scope of delivery. The transport case with moulded foam insert contains the complete equipment.
