Reduced power consumption up to 50 % 15 l/min flow at 10 bar Maximum pressure 135 bar Interchangeable valve screw allows for flow rates from 9 l/min to 15.0 l/min Flexible mounting orientation There are many instances in motorsport where high steering load is encountered at low engine speed, such as navigating the garage or pit box exit. Tradi- tional pumps have a ratiometric output which means the engine power at high revs is sacrificed for adequate pressure at low revs (pump must be oversized). The Bosch Variable Displacement Power Steering Pump (VPS15) reclaims wasted power by reducing delivery margin as pump speed increases, while maintaining high fluid flow at low RPM. The VPS15 also allows for greatly reduced fluid temperatures, potentially eliminating the need for a cooler. The VPS15 can accommodate flow rates from 9 to 15 l/ min with a replaceable flow screw at the pump outlet.
