Variable displacement pump

  • 03-Apr-2012 04:50 EDT


Rexroth's A1VO35 variable displacement pump reduces energy consumption while maintaining performance. Designed to fit in the same volume as a comparable constant displacement pump through an integrated cartridge valve, the A1VO35 can go off-stroke when demand is reduced, decreasing the energy needed to run the system while maintaining constant load pressure. The pump has similar dimensions and performance data as generally used, fixed-displacement pumps, with a displacement of 35 cm3 (2 in3), and is designed for speeds up to 3000 rpm. The A1VO35 is rated at a working pressure of 3600 psi (250 bar) and a peak pressure up to 4500 psi (310 bar) and features a flow capacity of up to 27.7 gal/min (105 L/min). Service life is comparable to previous versions used on large tractors and other mobile applications.
