Product Description

Rexroth A20VO60DFR1 Variable Double Hydraulic Piston Pump


Rexroth A20VLO Series variable displacement piston pumps are generally divided into single Rexroth variable displacement piston pumps, horizontal Rexroth variable displacement piston pumps, axial Rexroth variable displacement piston pumps and radial Rexroth variable displacement piston pumps.
Product Introduction:

Model: A20VO

Open circuit

Displacement: A20VO60, A20VO95, A20VO190, A20VO260, A20VO520

 

Features

-Variable pump with two axial piston rotary groups in swash- plate design for use in open circuit hydrostatic drives

-For use in mobile and stationary applications

-The pump consists of proven components from the A11VO (RE 92500), A10VO/53 (RE 92703) or A4VSO (RE 92050)

variable pumps

-The pump operates under self-priming condition, with tank pressurisation or with charge pump (sizes 190...260)

-A wide variety of controls are available

-Setting of the constant power control is  possible  via external adjustments, even when the unit is operating (only with power contol).

-The pump is available with a through drive to mount a gear pump or a second axial piston pump

-Output flow is proportional to drive speed and pump displacement and is steplessly variable between maximum and zero displacement

Features:
1. Single Rexroth variable displacement piston pump
The structural components mainly include an eccentric wheel, a plunger, a spring, a cylinder block, and two one-way valves. A closed volume is formed between the plunger and the cylinder bore. When the eccentric rotates one revolution, the plunger reciprocates up and down once, and moves downward to absorb oil, and moves upward to drain oil. The volume of oil discharged per revolution of the pump is called displacement, and the displacement is only related to the structural parameters of the pump.

2, horizontal Rexroth variable displacement piston pump

The horizontal Rexroth variable displacement piston pump is installed side by side with several plungers (generally 3 or 6). The piston is reciprocated by a crankshaft through the connecting rod slider or by the eccentric shaft. Liquid hydraulic pump. They also use valve-type flow distribution devices, and most of them are dosing pumps. The emulsion pumps in the coal mine hydraulic support system are generally horizontal Rexroth variable displacement piston pumps.
