Variable double pump for devices
with multi-circuit operation in the
open circuit, such as excavators,
cranes, drilling equipment etc.
- One suction port, two service
ports
- The pump functions using selfpriming,
tank charging or a charge
pump (sizes 190...260).
- Proven rotary group technology
- Possible to mount additional gear
pumps and axial piston pumps
on through drive
