New high-pressure open-loop axial piston hydraulic pumpBosch Rexroth is launching the A4VBO open-loop axial piston hydraulic pump that operates at a higher pressure than previously possible, making it suitable for applications in the open die forging industry.

Specially designed to provide a long service life and low level operating noise, the A4VBO hydraulic pump keeps future maintenance, and therefore unexpected costs, to a minimum. The modular design and excellent power-to-weight ratio aids installation and ensures performance, while a short response time helps to assist productivity.

Steve Smith, Bosch Rexroth Industry Sector Manager for Industrial Manufacturing Equipment, says: “The new A4VBO pump has been designed to deliver what we know is important to customers: improved bearing arrangements which provide durability, in addition to increased axial and radial loadings. An enhanced swashplate has created a fast-acting controller which means the pump will reach full flow quickly.

“The new pump provides a higher power to weight ratio when compared to traditional A4VSO models. This means that we can now offer machine builders a compact and yet powerful solution. Rexroth pumps are acknowledged by the industry as the best in the market, making the A4VBO a perfect addition to our portfolio.”

The A4VBO hydraulic pump comes in sizes 71cc, 125cc and 450cc. The nominal operating pressure is 450bar and peak 500bar, in comparison with traditional A4VSO models which reach 350bar. It also includes an electro proportional flow and pressure control option with various through drive options for mounting pilot and auxiliary pumps to the back of the A4VBO pump.
