F5VP2D28 / F5VP2D36 Durable Hydraulic Piston Main Pump, OEM Replacement Pump for DOOSAN DH70 & DH80-7 Mini Excavator

DOOSAN DH70 , DH80-7 Hydraulic Plunger Main Pump F5VP2D28 / F5VP2D36

The inner donkey pump of this pump can oil and control oil source, the inlet/outlet of this pump can connect with two check relief valves which is inside of pump ,and it ensures system never overload , operated directional stably , no concussion , with maximum displacement adjustable system, this pump applied to drive mixing cylinder of concrete transport truck and closed circuit hydraulic system widely.

Features:

- Swashplate design Axial variable plunger pump for hydrostatic transmission in a closed circuit.
- The flow is proportional to the drive speed and displacement.
- As the swash plate angle increases from zero to its maximum value, the flow increases proportionally.
- When the swash plate passes through the neutral position, the hydraulic oil flow direction changes smoothly.
- Two pressure relief valves are fitted to the high pressure port to prevent overloading of the hydrostatic drive (pump and motor).
- The high pressure relief valve can also be used as a charge check valve.
- Built-in charge pump rushes current oil pump and controls variable use.

- Optional with coupling flange for direct cardan shaft drive

- Integrated boost pump for boost and pilot oil supply

- Flow direction changes smoothly when the swashplate is moved through the neutral position

- High-pressure relief valves with integrated boost function

- Boost-pressure relief valve

- Through drive for mounting of secondary pumps

- Swashplate design
