Features Advantages
Combination of a gear pump giving a high
displacement at lower pressure with a radial
piston pump providing high pressure
with a lower displacement
Self-priming and venting (gear pump and
BRK)
HP 500, 700 or 1000 bar Modular pump system, numerous combinations
Each pump has its own suction and pressure connection Long operating lifetime
Special combination with twin gear pump available on request Very high suction performance
