Section II –Description
This manual contains service and maintenance information
for Vickers single and double pumps. These hydraulically
balanced cartridge type vane pumps are used to provide a
constant supply of hydraulic fluid under pressure and are
produced in three basic housing sizes: small, intermediate
and large. Cartridges of different displacement may be used
interchangeably in each series. These pumps can be used
as single units or two may be assembled on a common drive
shaft (double pump) providing an almost infinite number of
combinations. Figure 1 illustrates a cross sectional view of a
flange mounting, small and intermediate series combination
double pump, assembled for left hand rotation.
Figure 1.
Section III –Principles of Operation
A. Operation
Pumping is performed by cartridges consisting of a ring,
rotor, two bushings, twelve vanes and a locating pin or
screws (see Figure 2). The splined pump shaft rotates
driving a slotted rotor. Vanes within the rotor slots are thrown
out by centrifugal force and held out by system pressure to
follow a double lobed cam ring. Movement of the vanes in
and out as they follow the cam causes the chambers
between them to increase in size and pick up fluid from the
reservoir as the vanes cross the inlet porting. Chamber size
decreases when the vanes cross the outlet porting forcing
fluid out into the system.
The size of the cartridge ring determines the pump
displacement. Ring change alters delivery. However, the 11
gpm ring in the small series and the 36 gpm ring in the
intermediate series are used with wide vanes and rotor so
conversions to these capacities require additional change of
rotor, vanes and head.
B. Lubrication
None is required for current design models. Older designs
require lubrication of the front shaft bearing. A grease fitting
is provided on top of the pump body. (Some of the larger
pumps also incorporate a grease relief fitting on the bottom
of the body.) It is recommended that these fittings be
lubricated sparingly (approximately one tablespoonful every
six months) with a low pressure gun using a good quality,
high temperature, bearing grease.

7
CAUTION
Over-lubrication can damage the shaft seal.
C. Routine Inspection and
Maintenance
1. Make certain all hydraulic connections are tight to
prevent fluid leakage or entry of air into the system.Complete
overhaul may be accomplished by means of cartridge and
gasket kits.
2. Check fluid level in the reservoir to assure an
adequate supply to the pump intake. When adding fluid,
always pour it through a 200 mesh or finer screen.
3. Inspect the filter element and replace if dirty.
4. Inspect the fluid for contamination. If contaminated,
drain the system and thoroughly clean the reservoir. Change
the filters and flush the complete system with new fluid.
Again drain the system and refill with new fluid.
5. Check the reservoir air breather and replace if dirty.
D. Product Life
The longevity of these products is dependent upon environ-
ment, duty cycle, operating parameters and system clean-
liness. Since these parameters vary from application to
application, the ultimate user must determine and establish
the periodic maintenance required to maximize life and
detect potential component failure.
Section IV –Overhaul
A. General
Complete overhaul may be accomplished by means of car-
tridge and gasket kits.
B. Disassembly
Disassembly may be accomplished in the order shown in the
illustration (Figures 3 or 4).
WARNING
Before breaking a circuit connection, make certain
that power is off and system pressure has been
released. Lower all vertical cylinders, discharge
accumulators, and block any load whose movement
could generate pressure.
Prepare a clean, lint-free surface on which to lay internal
parts of the pump. Thoroughly clean areas adjacent to the
components being removed to minimize possibility of dirt
entering the system. Cap or cover all exposed ports and
openings into the system.
Inspect and replace as follows:
1. Vanes, for wear and sticking in rotor slots. Vanes
must move in slots from their own weight when dry. Replace
if defective. Stone new vanes lightly on an India stone to
remove sharp edges.
2. Ring, for scored or cross-grooved cam face. Replace
if grooved or scored.
3. Faces of rotor and bushings for wear and scoring.
Remove light scores by lapping; replace if heavily scored.
Stone new parts lightly to remove burrs.
4. Bearings for cracked or pitted races or pitted balls.
Replace if defective.
5. Shaft for wear at seal lip journal. Replace if scored.
6. Replace shaft seal, O-ring and head packing at each
teardown.
C. Reassembly
Assemble parts in reverse order of disassembly, noting the
following:
1. Assembly seals with spring toward inside of the
pump.
2. Coat all parts with compatible fluid and lightly
lubricate the lip of the shaft seal to prevent damage during
installation.
3. Install bearing and snap ring on shaft end and place
in the body.
4. Spring in the shaft seal must be toward the shaft
bearing.
5. Install cartridge parts so arrows on the parts are
pointed for intended rotation as viewed from the shaft end.
6. Assemble the pin so its small diameter end fits into
the body for right hand rotation (large end in body for left
hand rotation). See installation page 5.

A. Cartridge Assembly
Figure 2 illustrates a typical cartridge assembly and
installation, when viewed from the head end. The cartridge
assembly procedure is the same for both single and double
pumps, depending on the direction of shaft rotation.
The stepped diameter locating pin prevents improper assem-
bly of the cartridge. However, caution must be exercised to
install the cartridge properly for the direction of rotation desired.
The large series pump cartridges have a locating screw and a
retaining screw in lieu of the locating pin used in the small and
intermediate series.
NOTE
The direction of rotation (right hand or left hand) is
always determined by viewing the pump from the
shaft end.
B. Installation
Right Hand Rotation: Insert the small end of the located pin
into the small hole in the pump body at a 3 o’clock position.
Left Hand Rotation: Insert the large end of the located pin
into the large hole in the pump body at a 6 o’clock position.
C. Head Screw Adjustment
Some pump cover heads and intermediate heads (double
pumps) are provided with two small holes to match the two
diameters of the locating pin. Install the head so the pin fits
the hole size to prevent the pin from bending or shearing
when the pump is put into operation.
Pull the head down gradually, alternately tightening the
screws 180°from each other until the head seats evenly on
the bushing. Turn the shaft by hand during the process until a
light, smooth snugness is felt through a complete revolution.
Do not over-tighten the screws, causing the shaft to bind.
Before starting these pumps, check for freedom of move-
ment of the internal parts by turning the shaft by hand. Never
start a pump which shows evidence of binding.
CAUTION
A new or overhauled pump must be started under load
on the first rum. This will create a back pressure to
assure adequate internal lubrication. After a pump is
broken in, it can be started under ’’no-load” conditions.

9
Start the pump by ”jogging”the drive motor a few times to be
sure the pump is primed.
If the pump is new or has been overhauled, be certain it is prop-
erly installed. Check the direction of shaft rotation and align-
ment of the shaft with the drive motor. Since it is difficult to
achieve perfect shaft alignment, a flexible coupling must be
used.
Exercise care with pumps driven by belts, chain drives, spur
gears, etc. to prevent excessive side loading of the drive shaft.
Consult your Vickers’representative for recommendations on
these type drives.
Pump life will be shortened by operation beyond maximum
pressure and speed ratings. Since these units are positive
displacement, a relief valve must be used to limit maximum
system pressure to recommended limits.
Section VI –Troubleshooting
TROUBLE PROBABLE CAUSE REMEDY
Pump not delivering fluid Pump driven in wrong direction of rotation
Pump drive shaft broken or shaft key
sheared (direct drive)
Fluid intake pipe in reservoir blocked or oil
viscosity too heavy to pick up prime
Viscosity should not exceed 4000 S.S.U.
Air leaks at intake
Pump not priming
Oil level too low
Vane or vanes stuck in rotor slots
Must be reversed immediately to prevent
seizure. Check direction of drive rotation
against proper pump rotation as indicated by
arrow on body.
Remove pump from accessory mounting
pad and determine damage to pump car-
tridge. Replace needed parts.
Drain complete system. Add new fluid of
proper viscosity. Filter the new fluid as rec-
ommended. Check all filters for dirt and
sludge.
Check intake connection for air leak. Tighten
securely.
Loosen connection in outlet line. Bleed-off
air until fluid flows.
The fluid level must be above intake opening
in intake pipe. Check minimum drive speed
which may be too slow to prime the pumps.
Inspect rotor slots for wedged chips or for-
eign particles and replace all damaged
parts. Flush complete system thoroughly by
recommended processes and fill system
with new, clean hydraulic fluid.
Pump making noise Partially clogged intake strainer or
restricted intake pipe
Defective bearing
Air leak at pump intake piping joints or
pump shaft seal
Coupling misalignment
Pump must receive intake fluid freely or
cavitation will result. Drain system, clean
intake pipe, and clean or replace strainer.
Add new fluid and strain by recommended
procedures.
Disassemble pump and replace bearing.
Test by pouring oil on joints and around
drive shaft. Listen for change in operation.
Tighten joints affected. Check pump shaft
oil seal for leakage and replace if neces-
sary, in accordance with instructions out-
lined in this manual. Check shaft for scor-
ing at seal contact area and replace shaft if
grooving is evident.
Check shaft bearing and seal for possible
damage. Replace if necessary. Re-align
shafts.
