Features Advantages
Robust radial piston pump, valve controlled Preeminent power spectrum, broad range, multiport pumps, different media
Low piston clearance High volumetric efficiency on a wide speed range
Bearings are designed for maximum constant pressure (500 bar) Long operating lifetime
Self-venting Low noise level
Minimized dead volume of pistons, linked together with optimized design of suction valves Low pulsation
Combination with gear pump possible (see separate data sheet BKP) Enables supply of standard pumps as well as special customized models
