The Sunfab variable displacement pump with its rugged construction is designed for direct mounting at the auxiliary drive (P.T.O.) of commercial vehicles. Sunfab SVH is rotation-direction dependent and should be ordered in either right-hand or left-hand designs. With a max. displacement of 130 cm3/rev. and a peak pressure of 450 bar it is suited for many applications. This is complemented by the high self priming rate and the low noise level. The pump delivery flow is dependent on the present drive speed and geometric displacement. The flow is adjust­ ble in a range between 0 and Qmax. a Other advantages of Sunfab SVH: • • • • • Long service life is ensured due to the pressurized lubrica- • tion of the swash plate bearing shell. • 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 High power-to-weight-ratio 3114GB1601 Rev 1.3 - PAGE 1/20 Sunfab Hydraulics AB, Box 1094, SE-824 12 Hudiksvall, Sweden.

Description of the controllers LSNR Load-Sensing controller with integrated pressure limitation Pressure controller, adjustable directly at the pump. The Pressure controller automatically maintains a constant system pressure independant of the required flow. Therefore it is suited for constant pressure systems, where differing flow is required or as efficient pressure limitation of the hydraulic system Intermediate plates Intermediate plate only in combination with controllers LSNR or NR SVH 062, 092, 112: Intermediate plate with power controller (torque limitation) Product ”Pressure x Displacement”...
