piston type hydraulic pump

Axial Piston Variable Pump LMA4VTG (A4VTG) for mobile concrete mixers

 

Hanjiu Technology provide Piston hydraulic pumps for construction equipments.

LMA4VTG replace Rexroth A4VTG

Sunny A4VTG90 Rexroth Hydraulic piston Pump

A4VTG90 close circuit variable displacement piston pumps

 

 

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
