Danfoss Series 45 Open Circuit Axial Piston Hydraulic Pump
P & R Hydraulics is an official sales partner for Danfoss Power Solutions, of which the Series 45 open circuit axial piston hydraulic pump is a range of products we supply.
The Series 45 sets the standard for performance in open circuit pumps, as it is an industry leader in speed, efficiency and torque. It is:-
- Optimised for efficiency
- Integrated with electric controls
- Designed for low maintenance
The Series 45 can meet any demand through the large
portfolio of available options:-
 | |
| Series 45 pump (K frame) |
- 20 displacements
- 2 rotations
- 77 control options
- 3 choke options
- 3 gain orifices
- 21 shafts
- 101 aux/end cap configurations
- 6 seals
- 14 flanges
- 35 displacement limiter options
- 8 special hardware options
- 21 special features (colours and tags)
This Danfoss family of open circuit, variable piston
pumps, offers a range of displacements from 25 to 147 cm³/rev (1.53 to 8.97
in³/rev). With maximum speeds up to 3600
rpm and continuous operating pressures up to 310 bar (4495 psi), product
selection is easily tailored to the flow and pressure requirements of
individual applications.
The Series 45 pumps and PVG proportional
valves are a perfect combination for optimized, low noise, highly responsive
hydraulic systems. Both products work together using the load sensing principle
for maximum efficiency and conservation of energy. Load sensing controls match pump outlet flow
with system demand. This increases
efficiency and life over pressure compensated systems. State of the art
machinery requires highly efficient hydraulics to reduce fuel consumption,
engine emissions, and heat dissipation.
P & R Hydraulics can supply the Series 45 pumps as complete units or components. We also supply PVG proportional valves
(PVG16, PVG32, PVG100 and PVG120) as complete units built to your own
specificiations or separate components.
Our workshop and test rig enable our trained engineers to test, repair
and modify Danfoss units.
