Features Advantages
Robust radial piston pump, valve controlled: Preeminent power spectrum, broad range, explosion proofed, multiport pumps, different media
Low piston clearance: Very high volumetric efficiency on a wide speed range
Bearings are designed for maximum constant pressure (500 bar): Long operating lifetime
Optimized design of suction and pressure valves: Very high suction performance
Minimized dead volume of pistons, linked together with optimized design of suction valves: Self-venting
Modular pump system: Enables supply of standard pumps as well as special customized models
