V10, V20, V2010 and V2020 series fixed displacement vane pump Vickers "balanced blade formal structure." V10 and V20 single-pump rated flow are 1 to 7 USgpm and 6 至 13 USg pm. Double pump provides a power source that can supply two separate hydraulic circuits, or by merging two of the output flow to provide more traffic. In both applications, both pumps in the pump body. The result is a more compact, easy to install and can be driven through a coupling. V2010 double pump flow pump shaft 6 to 13 USgpm, cap side of the pump flow rate of 1 to 7 USgpm. V2020 double pump flow 6 to 13 USgpm, cap side of the pump flow rate of 6 to 11 USgpm. All types of pumps designed to use oil or synthetic flame-retardant liquid. The axis of rotation is clockwise or counterclockwise, but can be changed by fitting the inner member to change the direction of rotation.
