1. What is the Hydraulic Pump A7V20 A7V28 A7V40 A7V55 A7V58 A7V80 A7V107 A7V117 A7V160 A7V250 A7V355 A7V500 ?

A7V series pumps are classic bent-axis variable displacement axial piston hydraulic pumps , covering complete displacement models: A7V20, A7V28, A7V40, A7V55, A7V58, A7V80, A7V107, A7V117, A7V160, A7V250, A7V355, A7V500 (unit: mL/r).

It is specially developed for open-circuit hydrostatic transmission systems. With multiple optional control modes including constant power, constant pressure and manual control, it can realize stepless flow adjustment under fixed rotating speed. The pump supports a maximum peak pressure up to 40 MPa, featuring compact structure, strong pressure resistance, low vibration and low noise. Widely matched with mining equipment, construction machinery, metallurgical forging devices and marine hydraulic systems, our replacement pumps can achieve full dimensional interchangeability with original Rexroth products while supporting OEM customization services.

2. What makes the Hydraulic Pump A7V20 A7V28 A7V40 A7V55 A7V58 A7V80 A7V107 A7V117 A7V160 A7V250 A7V355 A7V500 ?
  • Full complete displacement spectrumCovers 20 mL/r to 500 mL/r full displacement specifications, fully meets flow demands from small engineering equipment to large heavy-duty mining and metallurgical machinery. Multiple control options such as constant power, constant pressure and manual control realize stepless flow regulation under fixed rotational speed for flexible system matching.
  • Superior high-pressure bearing capacityRated working pressure reaches 32 MPa with the maximum peak pressure up to 40 MPa. High-strength cast iron pump housing plus wear-resistant precision-machined cylinder blocks, pistons and slipper assemblies effectively resist pressure impact and reduce internal leakage, keeping volumetric efficiency above 91% in rated operation.
  • Stable & quiet operating performanceOptimized bent-axis structural layout lowers flow pulsation greatly. The pump runs smoothly with low vibration and low noise even under frequent load fluctuation and continuous heavy-load working conditions, reducing extra wear of peripheral hydraulic components.
  • Perfect interchangeability with original partsOur aftermarket A7V pumps strictly follow original Rexroth dimensional standards on installation size, spline parameters and oil port layout. Customers can directly replace the failed original pumps without modifying equipment structures or pipelines to cut maintenance downtime and replacement costs.
  • Strict factory inspection & reliable export packagingEach pump passes full hydraulic pressure test before delivery. Anti-rust treatment is applied to all metal parts, matched with moisture-proof wrapping and solid wooden export cases to avoid rust and collision damage during long-distance ocean transportation.
  • Flexible customized support for global partnersCustomizable items include rotation direction, control valve type, pump body paint color and brand logo marking. We also supply complete overhaul spare parts together with technical support for installation and troubleshooting to help distributors develop local business.


3. What is the working pressure range of Hydraulic Pump A7V20 A7V28 A7V40 A7V55 A7V58 A7V80 A7V107 A7V117 A7V160 A7V250 A7V355 A7V500 ?

  • All models of the A7V series share unified pressure parameters:
  • Continuous rated working pressure: 32 MPa (4641 PSI)

  • Maximum instantaneous peak pressure: 40 MPa (5802 PSI)

  • The pump can stably sustain long-term operation under 32 MPa conventional working pressure, and withstand short-time pressure surges up to 40 MPa during equipment startup or load shocks.

4. Can Hydraulic Pump A7V20 A7V28 A7V40 A7V55 A7V58 A7V80 A7V107 A7V117 A7V160 A7V250 A7V355 A7V500 replace other brands?

  • Direct replacement for original Rexroth A7V pumpsOur A7V series pumps (A7V20/28/40/55/58/80/107/117/160/250/355/500) strictly adopt the original Rexroth dimensional standards for mounting flanges, oil port layout, spline dimensions and control interface. They achieve 100% physical interchangeability, which means customers can install them directly without modifying equipment brackets, pipelines or control circuits.The hydraulic performance including pressure rating, volumetric efficiency and variable flow characteristics is fully consistent with original Rexroth products.
  • Conditional functional replacement for other mainstream brandsThis pump can serve as a functional substitute for equivalent bent-axis piston pumps from Parker, Eaton, Atos and other brands only if the core parameters are matched, including displacement, rated pressure, installation size and control mode. If the overall structural dimensions are different, mechanical modification of the equipment will be required for installation.
  • Key replacement advantagesCompared with original imported pumps and other brand counterparts, our replacement pumps have stable working performance, longer service life and more competitive prices. We also supply complete repair spare parts and professional technical support for installation and debugging.
  • NoticeCross-brand replacement must confirm four core parameters in advance: displacement value, pressure parameter, installation dimension and control method to avoid system mismatch and equipment failure.


5. What is the typical speed range of Hydraulic Pump A7V20 A7V28 A7V40 A7V55 A7V58 A7V80 A7V107 A7V117 A7V160 A7V250 A7V355 A7V500 ?


  • Minimum stable working speed: 500 rpm

  • Recommended continuous rated working speed: 1500 ~ 2200 rpm (universal safe operating interval for long-term heavy-load operation)

  • Maximum allowable instantaneous speed:

  • Small displacement models (A7V20 / 28 / 40 / 55 / 58 / 80): Max short-term speed ≤ 2800 rpm

  • Medium & large displacement models (A7V107 / 117 /160 /250 /355 /500): Max short-term speed ≤ 2200 rpm ~ 1200 rpm (the larger the displacement, the lower the limit speed)

  • Practical Advice

    Long-term continuous operation is suggested to stay within 1500–2000 rpm. Excessive rotational speed will aggravate internal component wear, raise oil temperature and shorten the pump service life.

6. Do you provide OEM or customized services?

  • Yes, comprehensive OEM and personalized customization services are available for all specifications of the A7V series hydraulic pumps.
  • OEM service items: Laser engraving of customer brand logos, compiling exclusive customer part numbers, customizing outer carton & wooden box printing.
