The Bosch Rexroth A10VSO71DRG (31R-PPA12KB3) is a variable pump in the A10VSO series 31, an axial plunger design for open loop hydraulic transmission systems. The following is a detailed description of the pump:
Design features:
Designed with axial piston rotating group for open circuit hydraulic transmission system.
The flow rate is proportional to the transmission speed and displacement.
The flow rate can be adjusted stepless by adjusting the plunger plate.
Provided with 2 oil drains.
Have excellent suction characteristics.
Low noise level and long service life.
Good power to weight ratio, with good power performance.
Wide control range and short control response time.
Can be diametrically fitted with gear pumps and axial piston pumps of the same size, i.e. 100% diametrically fitted.
Suitable for the operation of mineral oil and HF hydraulic fluids.
In sizes 18 to 100.
Typical pressure is 280 bar, maximum pressure is 350 bar.
Hydraulic fluid selection:
Designed for use with HLP mineral oils according to DIN 51524-2.
Please refer to the following data sheet for application instructions and requirements for hydraulic fluids before the project plan begins:
90220: Hydraulic fluids based on mineral oils and related hydrocarbons
90221: Environmentally friendly hydraulic fluid
90222: Fireproof, waterless hydraulic fluids (HFDR/HFDU)
90223: Fire-resistant, water-containing hydraulic fluids (HFAE, HFAS, HFB, HFC)
Hydraulic fluids should be selected to ensure that the operating viscosity over the operating temperature range is in an optimal range.
Hydraulic fluid filtration:
Finer filtration improves the cleanliness of the hydraulic fluid, thereby extending the life of the axial piston pump.
A cleanliness level of at least 20/18/15 should be maintained according to ISO 4406.
Where the viscosity of the hydraulic fluid is less than 10 mm²/s (e.g. due to high temperatures during short periods of operation), a cleanliness class of at least 19/17/14 according to ISO 4406 is required at the outlet.
The Rexrox A10VSO71DRG (31R-PPA12KB3) is a powerful hydraulic pump suitable for hydraulic transmission systems in a variety of industrial applications. Its reliability, performance and flexibility make it ideal for use in hydraulic control systems.
