3115 GB Pump SVH 062, 092, 112 The Sunfab variable displacement pump with its rugged construction is designed for direct mounting at the auxiliary drive (P.T.O.) of commercial vehicles. flow is dependent on the present drive speed and geometric displacement. The flow is adjust ble in a a range between 0 and Qmax. Long service life is ensured due to the pressurized lubWith a max. displacement rication of the swash plate of 112 cm3/rev. and a peak bearing shell. pressure of 400 bar it is Sunfab SVH is rotationsuited for many applicadirection dependent and tions. This is complemented by the high self priming should be ordered in either right-hand or left-hand rate and the low noise designs. level. The pump delivery Other advantages of Sunfab SVH: • Short reaction time when resetting the flow • Compact installation dimensions • High pressure • Externally drained for best cooling • Rugged construction and long service life • Low noise emission • Low power-to-weightratio 1
