Technical data

• Specially designed for demanding applications with continuous pressures (S1) up to 700 bar → long economic lifetime!

• Explosion-prone hydraulic constructions (according ATEX standard)

Applications• Radial piston pump of modular design• With valve controlled pump elements• can be supplied with 3, 5 or 7 pistons per

section (depending on size)• Design as multiple circuit pump on re-

quest• Low-friction pumping elements with low

sliding speed

Design

• High volumetric efficiency• Self-priming and venting• Low pulsation• Low noise level
