 CZPT A8VO pump
 
CZPT piston double pump A8VO55, A8VO80, A8VO107, A8VO140, A8VO200

Description  

Open up circuit
Sequence sixty one / 63
Management units: LAOH2, LAOK, LAOKS, LAOKH1, LAOKH2, LAOKH3, LA1H2, LA1S, LA1K, LA1KS, EP, LA1KH1, and so forth.
Nominal pressure 350 bars. Peak stress four hundred bars
 
– Variable double pump A8VO with two axial tapered piston rotary groups of bent-axis style for hydrostatic drives in open up 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 ideal for direct mounting on the flywheel circumstance in diesel engines
– 1 common suction port for auxiliary pump and equally circuits
– A extensive selection of control instruments is offered for distinct control and regulating functions
– Personal electrical power controller
– Integrated auxiliary pump with stress-relief valve, optionally with further stress-reduction valve
– Electricity get-off for mounting axial piston and gear pumps
– Exceptional power to excess weight ratio
– Lengthy provider daily life
