A10VM28 Hydraulic Axial Piston Pump

Product Overview

A10VM28 is a compact variable‑displacement Hydraulic piston pump from Bosch Rexroth, designed for mobile open‑circuit hydraulic system. As the core power unit, this reliable hydraulic pump converts mechanical energy into adjustable high‑pressure hydraulic flow, delivering stable power for small and medium‑sized construction Machine. Adopting swash‑plate axial piston structure and optimized two‑point control design, it features high volumetric efficiency, compact size, fast response and strong anti‑pollution performance. It is widely applied for original equipment matching, field overhaul and aftermarket spare‑parts replacement of mini excavators, aerial work platforms, agricultural machinery and other light‑duty mobile Machine. The operation stability of this Hydraulic piston pump directly determines the working reliability and service life of the whole hydraulic system.

Working Principle

The prime mover drives the input shaft of this Hydraulic piston pump, pistons inside the cylinder block perform reciprocating motion along the swash plate. Periodic volume change of piston chambers realizes oil suction and high‑pressure oil discharge. The built‑in control component adjusts the swash‑plate angle according to pressure feedback from the hydraulic system, changes pump displacement to match load demand and avoid overload damage to the Machine. When internal friction pairs of the hydraulic pump are worn, faults such as insufficient flow, pressure drop, high internal leakage and abnormal noise will occur. Replacing a qualified A10VM28 pump can fully restore the performance of the complete hydraulic system.

Core Advantages

1. Mature Rexroth mobile hydraulic design, stable operation under medium‑pressure heavy‑load conditions, greatly improves the reliability of the hydraulic system.

2. Compact dimension and lightweight structure, suitable for narrow installation space of small construction Machine, simplifies pipeline arrangement.

3. Two‑point variable control, automatically adjusts flow according to working conditions, reduces energy consumption and heat generation of the hydraulic system.

4. High‑precision rotating group, strong contamination resistance, adapts to harsh dust and impurity environments on construction sites, extends service life of the Hydraulic piston pump.

5. Strictly follows original mounting dimensions, good interchangeability, direct replacement without secondary machining, convenient for on‑site maintenance and overhaul.

Application Range

A10VM28 Hydraulic piston pump is an essential power supply component for mobile open‑circuit hydraulic system. It provides stable hydraulic power for mini excavators, aerial lifting equipment, agricultural machinery, small construction machinery and other mobile Machine. Widely supplied for OEM manufacturers, machinery repair workshops and global aftermarket spare‑parts trading business.
