Physical and Operating Characteristics
The Vickers VTM27, VTM28, VTM40, VTM41, and VTM42 Power Steering Pump units are used primarily to
supply a flow of hydraulic fluid for operation of power steering mechanisms. Pumps in this series are of the
balanced vane-type and have a constant rate of delivery per revolution. Direction of pump rotation and
pumping capacity may be changed to suit specific applications. The pumps are available with an integral
reservoir or with a manifold for remote reservoir installations.
