Section II – Description
A. General
Pumps in this series are used to develop hydraulic fluid flow for
the operation of Mobile equipment. The positive displacement
pumping cartridges are the rotary vane type with shaft side
loads hydraulically balanced. The flow rate depends on the
pump size and the speed at which it is driven.
All units are designed so that the direction of rotation,
pumping capacity and port positions can be readily changed
to suit particular applications.
B. Assembly and Construction
The V200 series pump illustrated in the cutaway in Figure 1
is representative of all single pumps in this series. The unit
consists principally of a ported body and cover, a drive shaft
supported by two ball bearings, a pumping cartridge and a
pressure plate. Components of the pumping cartridge are an
elliptical cam ring, a slotted rotor splined to the drive shaft
and twelve vanes fitted to the rotor slots.

14 Special Features
As the rotor is driven by the driveshaft, the vanes generate
fluid flow by carrying fluid around the elliptical ring contour
(see Section III). Fluid enters the cartridge through the inlet
port in the body and is discharged through the pressure plate
to the outlet port in the cover.
C. Flow Control and Relief Valve
V200 pumps are available with an integral flow control and
relief valve in the pump cover. This limits the final flow in the
system to a maximum prescribed rate and prevents
excessive pressure buildup. Fluid not required in the system
is recirculated to tank.
D. Application
Pump ratings in GPM as shown in the model coding are at
1200 RPM. For ratings at other speeds, methods of
installation and other application information, Vickers
application enginering personnel should be consulted.
