Hydrostatic Speed Variator. Manual control as standard , but can be offered with 4-20mA control package as option. 1:1 throughput , so no overall speed reduction (unlike MV ) so does not require a larger pump to give comparable max flow of fixed flow unit. Typical control range is appx 3-100% , in most cases control down to 0% can be obtained but it is load dependent (variable) so we quote 3% minimum. Transmission losses typically require a larger motor (than standard) to be fitted in order to maintain the same pressure performance.
