The WIKA CPP1000-M hydraulic spindle pump is primarily designed for the testing and calibration of small-volume pressure measuring instruments. A fine adjustment valve is available as an optional accessory; when the fine adjustment valve is installed, only one shut-off valve can be fitted for a single test connection.

The rotating spindle operates entirely within the pump body. This design eliminates the negative effects of bending torque associated with spindles that extend outside the body during rotation. A key advantage, especially for field use, is that the overall dimensions of the hand spindle pump remain unchanged during operation, with no external protrusion of the spindle.
