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
