Special radial piston pumps SRK701/702

Operating pressure up to 700 bar
Displacement volume 0,24 up to 8,14 cm³/rev
Max. rotation speed 1800 rpm

Features Advantages
Robust radial piston pump, valve controlled Very high volumetric efficiency on a wide speed range
Low piston clearance Self-venting
Bearings are designed for maximum constant pressure (700 bar) Low pulsation
Minimized dead volume of pistons, linked together with optimized
design of suction valves
Long operating lifetime
Modular pump system Suitable for operation with fluids with
reduced lubricating properties
