KPP05 piston pump uses shape-memory allow and bundled-wire technology to deliver a precision stroke using only AC or DC electrical power. Displacement or pressure control can be done with additional sensors, offering the functionality of a motor, pump and proportional valve in on compact unit. Compatible with a wide range of fluids, it provides a high pressure-to-size ratio with pressures as high as 145 psd, flow rates of 2.6 GPH, and IP67 environmental protection.
