Areas of application
Test pumps are used to generate pressure for the testing, adjusting and calibrating mechanical and electronic pressure measuring instruments by means of comparative measurements. These pressure tests can be carried out in laboratories, workshops or on-site at the measuring point.
Ease of operation
When the device under test and a suitably accurate reference measuring instrument such as the 3D Series 25 Test Gauge or the 3D Accu-Cal Plus Digital Test Gauge are connected to the test pump, after actuating the pump, the same pressure will act on both measuring instruments. Calibration or adjustment of the device under test can be carried out by
comparing the two measured values at any pressure value. In order to enable the accurate generation of the measuring points, both test pumps are fitted with a fine adjustment valve.
Easy handling
Despite the very compact size, the handpump enables simple and accurate test pressure generation. Using the CPP30 a maximum of 500 psi (35 bar) pneumatic pressure can be generated. With a press of a change-over switch, Vacuum generation down to -13.75 psi (-950 mbar) is also possible using the same unit. The maximum pressure or vacuum achievable depends on the attached test volume. Each pump also has a fine adjustment valve to enable the precise setting of the pressure. The reference instrument is fitted directly to the top of each pump, and the device under test is connected via a connection tube (length 0.5 M) with ¼“ NPT female thread, included with the hand pumps. The reference instrument is not included in the basic models but can be ordered by referring to the appropriate 3D Product Literature.
