Bosch launches axial piston pump for smaller power classes

Axial Piston PumpRexroth’s AV1O offers the benefit of load sensing principles used on larger machines’ axial piston variable pumps in which hydraulic systems provide power only when needed. As fuel prices continue to fluctuate dramatically, the mobile machine builder needs to find ways to make their machines more energy efficient, without sacrificing the package size or increasing costs.

Bosch designed the A1VO series to bring the fuel savings of load-sensing technology to the smaller power classes of mobile machinery. In addition to being a cost-effective alternative to fixed pumps, the A1VO35 offers an economical switch from open-center design to a load-sensing system.

To make the switch appealing for manufacturers, the A1VO35 has dimensions and performance data similar to that of fixed-displacement pumps. It offers speeds up to 3,000 rpm, a rated working pressure of 3600 psi, peak pressure up to 4500 psi and a flow capacity of up to 27.7 gallons per minute. And its overall efficiency is nearly 90%. Yet its displacement is only 35 cubic centimeters. Its useful service life — 6,000 operating hours — is comparable to that of the larger Rexroth A10V series pumps used on large tractors and mobile applications.

The energy savings provided by the A1VO35 load-sensing technology lowers diesel fuel consumption by more than 2,500 gallons (10,000 liters) over its useful life and reduces noise emissions by up to 3 dB(A) over conventional pumps. These benefits will make it easier for applications using A1VO35 to meet increasingly strict international regulations.

With its universal through-drive, the A1VO35 is easy to combine with a broad range of axial piston pumps, gear pumps and other hydraulic pumps. That makes the Rexroth A1VO35 a good choice for applications such as tractors, skid steers, forklifts, gate lifts and truck-mounted cranes for on-road vehicles.
