WIKA Operating Instructions Hand Spindle Pump 6
2. Product description
2.1 General product information
■ Application
Hand spindle pumps are used to generate pressures for checking, adjusting and
calibrating mechanical and electronic pressure measuring instruments by compara-
tive measurements. These pressure tests may be carried out in laboratories,
workshops or on site at the measuring point.
■ Functionality
If the instrument to be tested and a sufficiently accurate reference measuring instru-
ment are connected up to the test pump, the same pressure is applied to the two
measuring instruments when the hand spindle pump is operated. By comparing the
two measured values at random pressure values, the accuracy can be verified or
the instrument under test can be adjusted. The hand spindle pump is equipped with
a precision spindle to make it possible to approach measuring points exactly. The
CPP1000-M/-L is particularly notable for the rotating spindle that only runs inside
the body of the pump. This eliminates the negative effect of a bending torque on a
spindle turning outside the body and offers the advantage, especially for use in the
field, that the dimensions of these hand spindle pumps do not change during opera-
tion due to the spindle turning.
