Concrete Pump SCHWING / Putzmeister A10VO28 Accumulator Pump
Hanjiu Technology provide Piston hydraulic pumps for construction equipments.
Specifications:
- High pressure pump for the drum drive in mobile concrete mixers
- Size 5 … 90
- Nominal pressure 400 bar
- Maximum pressure 450 bar
- Closed circuit
Features:
- As the swash plate angle increases from zero to its maximum value, the flow increases proportionally.
- Built-in charge pump rushes current oil pump and controls variable use.
- Flow direction changes smoothly when the swashplate is moved through the neutral position
- Boost-pressure relief valve
- Through drive for mounting of secondary pumps
- Optional with coupling flange for direct cardan shaft drive
- Swashplate design
- Swashplate design Axial variable plunger pump for hydrostatic transmission in a closed circuit.
- The flow is proportional to the drive speed and displacement.
- Integrated boost pump for boost and pilot oil supply
- 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.
- High-pressure relief valves with integrated boost function
Variable displacement axial piston pump in swashplate design is designed for open circuit applications. It can be used in mobile and industrial applications. Flow is proportional to the drive speed and the displacement.
