The WIKA CPP1000-L hydraulic spindle pump is primarily designed for the testing and calibration of small-volume pressure measuring instruments. It features a narrow rear flange, sealed reservoir, and an integrated side-mounted fine adjustment valve.

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 operation. A key advantage, especially for field use, is that the overall dimensions of the hand spindle pump remain unchanged during operation, as the spindle does not protrude externally when turning.

Features

• Compatible pressure media: mineral oil-based fluid or single distilled water (water-based hydraulic fluids are not suitable)
• 2 x G1/2 female thread, freely rotating test connections, with 4.5in (115mm) distance between connections
• Side-mounted fine adjustment valve for precise pressure control
• Robust construction: brass cylinder, stainless steel piston, and aluminum rear flange
• Spring-loaded thrust pad for smooth, stable operation
• Removable star handle for flexible operation and storage
• EAC approval
• Sealed reservoir and narrow rear flange for reliable field and laboratory use
• Internal rotating spindle design, maintains fixed dimensions during operation, eliminates bending torque risk
