Piston pump delivers displacement suitable for precision metering

Kinitics Automation has announced the KPP05 piston pump, a shape memory alloy-based positive displacement pump that uses proprietary Bundled Wire technology to deliver a precision stroke. Driven by the company’s KLA05 Linear Actuator, the product requires only AC or DC electrical power to operate and allows for displacement or pressure control when additional sensors are used.

This fluid power product offers the functionality of a motor, pump, and proportional valve in a single compact unit. The pump is compatible with a wide range of fluids and provides a high pressure-to-size ratio. Equipped with a standard 25 mm bore, the pump offers a number of features and benefits that distinguish it from other types of pumps:

• Piston positional accuracy of +/- 5 µm
• Rated pressure to 10 Bar (145 psi)
• Displacement up to 3.3 cc (0.2 cu. in.)
• Flow rates up to 10 LPH (2.6 GPH).
• Configurable ports
• IP67 environmental protection

The KPP05 Piston Pump may also be configured with alternate bore sizes when higher pressures or displacements are required. The product can also be equipped with a variety of accessories, including a range of mounting brackets and an adjustable home position switch.

Potential applications for the Kinitics Automation KPP05 Piston Pump include acting as a master cylinder for brake and clutch control, a hydraulic pump for grippers and clamps, and as a precision metering pump.
