Variable-volume piston pumps

P1/PD pumps have integrated digital electronics to control functions in real time. Windows-based software allows proportional control of pressure, displacement, torque limiting, anti-stall, and constant flow. Sensors for pressure, speed, temperature, and displacement optimize pressure and flow output. They operate at pressures to 280 bar with displacements to 75 cc/rev.
