A8vo200 CZPT piston Pump CZPT Model extensively used
CZPT piston double pump A8VO55, A8VO80, A8VO107, A8VO140, A8VO200
| Description |
Open circuit
Sequence 61 / sixty three
Handle units: LAOH2, LAOK, LAOKS, LAOKH1, LAOKH2, LAOKH3, LA1H2, LA1S, LA1K, LA1KS, EP, LA1KH1, and so on.
Nominal strain 350 bars. Peak strain 400 bars
– Variable double pump A8VO with two axial tapered piston rotary groups of bent-axis design and style for hydrostatic drives in open circuits
– The flow is proportional to the input velocity and to the displacement, and is infinitely variable from qV max to qV min =
– The pump is appropriate for direct mounting on the flywheel case in diesel engines
– 1 frequent suction port for auxiliary pump and both circuits
– A vast variety of management instruments is obtainable for different control and regulating functions
– Personal electricity controller
– Integrated auxiliary pump with force-aid valve, optionally with additional force-reduction valve
– Electricity just take-off for mounting axial piston and gear pumps
– Excellent electricity to excess weight ratio
– Lengthy service existence
