4 They guarantee smooth operationand a low-pulsation flow. The proveninvolute splines optimized in terms ofvolumes permit a compact the gears are rotating, oil issucked into the housing and into thespace between pinion and internalgear. The two gears run totally freelyover a wide range of their circumfe-rence, which guarantees an excellentsuction behaviour of the circumferential direction, the toothspaces are sealed off by the meshingteeth and the filler. Axially, an almostgap-free sealing is achieved by axialdiscs.

5 The volumetric losses are the-refore minimal. The oil sucked into thepump is displaced by the tooth tipsentering the tooth user benefits from the new pumpseries in the following ways, amongother things: Extremely low noise emission Extremely favourable size/displace-ment ration Long service life owing to plain bea-rings and balancing of forces High overall efficiency Suitable for building up multiple-flow pump Pumps of the same size or ofdifferent sizes can be combined witheach other to form double Pumps ormultiple-flow Pumps . The possibility ofcombining them with Voith mediumand low-pressure Pumps results in aparticularly wide field of with Pumps from diffe-rent manufacturers is possible as 25 6 728194a4b310 Design1 Pinion shaft2 Internal gear3 Filler pin4a Filler-segment carrier4b Filler-sealing segment5 Axial disc6 Axial pressure area7 Plain bearings8 Housing9 Hydrostatic bearing10 Cover with bleeder screwIPVIPVD esignInternal gear pumpMountingSAE or VDMA flangePipe connectionSAE J 518 c code 61 Direction of rotationClockwise or anti-clockwiseInlet
