Detailed description

This is a swashplate-designed variable displacement axial piston pump specially engineered for hydraulic open circuit systems. Its output flow is strictly proportional to the driving speed and displacement volume. By precisely adjusting the swashplate angle, the pump displacement can be steplessly and infinitely varied to accurately match different flow and pressure demands of the hydraulic system. The pump adopts standard ISO mounting flange design, which ensures convenient installation, reliable positioning and strong versatility for equipment assembly. It is configured with flange connections complying with SAE metric specifications, realizing standardised pipeline matching and easy modular connection. Two independent case drain ports are reserved for smooth discharge of internal leakage oil and effective heat dissipation. Meanwhile, the pump delivers excellent suction performance and stable suction characteristics, enabling reliable operation under normal working conditions and adapting to various complex hydraulic application scenarios.

Power	P=(2π ∙ T ∙ n)/60000=(q_v∙ Δp)/600 ∙ η_t	kW

Key

V_g Displacement per revolution in [cm^3]

Δp Differential pressure [bar]

n Rotational speed [rpm]

η_v Volumetric efficiency

η_mh Hydraulic-mechanical efficiency

η_t Total efficiency (η_t= η_v*η_hm)

Notice

▶Theoretical values, without efficiency and tolerances;values rounded

▶Operation above the maximum values or below the minimum values may result in a loss of function, a reduced service life or in the destruction of the axial piston unit. Bosch Rexroth recommend testing the load by means of experiment or calculation/simulation and comparison with the permissible values.

¹⁾ The values are applicable:

- to the optimum viscosity range from V_opt = 36 to 16 mm²/s

- to hydraulic fluid based on mineral oils

²⁾ The values apply at absolute pressure p_abs = 1.0 bar at suction port S.

³⁾The data are valid for values between the minimum required and maximum permissible rotational speed. Valid for external excitation(e.g. diesel engine 2 to 8 times rotary frequency, cardan shaft twice the rotary frequency). The limit value is only valid for a single pump.The load capacity of the connecting parts must be considered.
