FAQ:

Here's an FAQ about the A10VSO28 hydraulic pump:

Q1: What is the A10VSO28 and what are its key features?

The A10VSO28 is an axial piston variable pump designed for open circuit hydraulic systems. It features a swashplate design that allows for stepless flow variation by adjusting the swashplate angle. Key characteristics include excellent suction performance, low noise operation, long service life, high power-to-weight ratio, and the ability to handle continuous operating pressures up to 280 bar (with peak pressures up to 350 bar). It also has two housing drain ports for improved reliability.

Q2: What are the typical technical specifications of the A10VSO28 pump?

The pump has a nominal displacement of 28 ml/rev. It typically operates at a rated speed of 1500 rpm and can handle a maximum continuous pressure of 28 MPa (280 bar), with peak pressures up to 35 MPa (350 bar) momentarily. It offers a volumetric efficiency ≥94% and a total efficiency ≥85%. The pump's weight is approximately 23.5 kg, and it requires a fluid inlet pressure (suction pressure) of around 14 bar.

Q3: What different control options are available for the A10VSO28 series?

The A10VSO28 series offers various control options to suit different application needs. These include pressure control (DR), remote pressure control (DRG), and pressure-flow control (DFR1). For example, common model variants include A10VSO28DR/31R-PPA12N00 (pressure control) and A10VSO28DFR1/31R-VPA12N00 (pressure-flow control).

Q4: Where is the A10VSO28 pump commonly used?

This pump is widely used in industrial machinery and mobile equipment where robust hydraulic power is required. Common applications include construction machinery (e.g., pavers for asphalt or concrete), press machines, metal processing and mining equipment, engineering machinery, and light industrial equipment. Its versatility also makes it suitable for marine applications and civil aviation ground support equipment.

Q5: What are the advantages of the through-shaft design?

Many A10VSO28 models feature a through-shaft design (also called). This allows for the connection of additional pumps (like gear pumps or other axial piston pumps of the same size) to the same drive shaft, creating compact multi-pump systems for powering multiple circuits from a single prime mover. This enhances system integration flexibility and saves space.
