The energy-saving e-Varioserv® power steering pump provides the amount of oil needed at any time for operation of hydraulic steering systems in commercial vehicles. The pump is designed primarily for connection to the air compressor or a power take-off on an engine. The shaft connects by means of a cross-slotted disk or splines.
lower temperature in the steering system, which means less cooling required and improved system efficiency
lower fuel consumption and CO₂ emissions compared to a conventional power steering pump (depending on vehicle type, up to 0.3 l/100 km or 7.8 g CO₂/100 km)
