Variable displacement pump A1VO


The compact variable pump A1VO can save
up to 10,000 liters of Diesel

The A1VO axial piston variable displacement pump designed by Rexroth especially for the segment of small tractors reduces diesel fuel consumption up to 10,000 liters over the entire useful life of 6,000 operating hours. As a manufacturer Rexroth for the first time offers a cost-effective alternative to constant displacement pumps and enables for the first time an economical switch from the traditional open-center design to a load-sensing system. This approach summons hydraulic power as it is needed. Simulations based on a 90 hp diesel engine actually used in the marketplace verify fuel savings of between 10 and 15 percent per operating hour in mixed usage.
