Product Description

Rexroth A22VG045 Series Axial Piston Tandem Variable Pumps

Product Overview: The Rexroth A22VG045 series (Series 40) is a high-performance tandem variable displacement pump specifically engineered for hydrostatic closed-circuit transmissions. Models such as the A22VG045EP1P0403… (Part No. R902148834) feature two independently adjustable pumps on a single drive shaft, providing precise power distribution for the left and right travel drives of skid steer loaders, compact pavers, or harvesters. Utilizing advanced EP (Electric Proportional Control) technology, operators can achieve ultra-smooth starts, steering, and infinitely variable speed control via electronic joysticks, significantly boosting operational efficiency and comfort.

Key Technical Advantages:

  • Integrated Tandem Design: Delivers dual-channel independent output within a compact housing, significantly saving space in engine compartments and simplifying hydraulic plumbing.

  • High-Response EP Control: Provides lightning-fast displacement adjustments based on electronic current signals, ensuring smooth acceleration/deceleration and preventing engine stalling under heavy loads.

  • Heavy-Duty Traction Capability: Rated for continuous operation at 300-350 Bar (5000 PSI) with peak capability up to 400 Bar, guaranteeing long-term reliability in harsh off-road environments.

  • Built-in Charge Pump & Valves: Features an integrated charge pump and high-pressure relief valves to maintain circuit stability and cooling flow during frequent direction changes.

  • 100% OEM Standard Compatibility: Manufactured to strict Rexroth Series 40 specifications, ensuring mounting flanges and splined shafts (e.g., S7 spec) align perfectly for a seamless “drop-in” replacement.

Detailed Models & Parameters:

  • Core Series: Rexroth A22VG / A20VG Series 40.

  • Full Model Keywords: A22VG045EP1P0403/40BRNB2S73UB2S5A-S.

  • Key Part Number: R902148834.

  • Displacement: 45.0 cm³/rev (per tandem section).

  • Pressure Ratings: Rated at 300-350 Bar (4350-5075 PSI) continuous; Peak capability up to 400 Bar.

  • Control Type: EP1P (Electric Proportional Control with Pressure Cut-off).

  • Target Applications: Skid Steer Loaders, Compact Pavers, Forestry equipment drive systems, and Hydrostatic vehicle chassis.
