Combination pumps BKP

Operating pressure LP up to 250 bar
Operating pressure HP up to 1000 bar
Displacement volume LP 4.0 to 62.7 cm³/rev
Displacement volume HP 0.24 to 8.14 cm³/rev
Rotation speed 600 to 2000 rpm

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
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
