Bosch Rexroth has launched an open-loop axial piston pump designed to work at high pressure, making it particularly suitable for applications in the open die forging industry.

The compact A4VBO — available in sizes 71cc, 125cc and 450cc — is designed to deliver improved bearing arrangements and increased axial and radial loadings.

An enhanced swashplate has created a fast-acting controller, enabling the pump to reach full flow quickly.

The A4VBO’s nominal operating pressure is 450 bar and peak 500 bar. The system also features 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.

Key benefits

  • The A4VBO is designed to provide a long service life and low-level operating noise.
  • The pump keeps future maintenance — and therefore unexpected costs — to a minimum.
  • Its modular design and excellent power-to-weight ratio aids installation and ensures good performance.
  • The pump’s short response time helps to improve productivity.
