The A4VG axial piston variable pump in swash plate design for hydrostatic closed circuit transmissions
– Movement is proportional to drive pace and displacement and is infinitely variable
– Output flow boosts with the swivel angle of the swash plate from to its greatest benefit
– Stream path alterations effortlessly when the swash plate is moved via the neutral situation
– A extensive assortment of extremely adaptable control units is offered for diverse control and regulating functions
– The pump is equipped with two pressure-aid valves on the large stress ports to defend the hydrostatic transmission (pump and motor) from overload
– The high-force relief valves also perform as enhance valves
– The built-in boost pump acts as a feed and management oil pump
– The optimum increase pressure is limited by a built-in boost pressure reduction valve
– The integral pressure reduce-off is CZPT
