VPDE, Denison Vane Pumps
Vierzon - France
Start-up instructions & recommendations Series T7 - T67 - T6, Denison Vane Pumps
1 . 1 . GENERAL : All Parker vane pumps are individually tested to provide the best
quality & reliability. Modifications, conversions & repairs can only
be done by authorized dealers or OEM to avoid invalidation of the
guarantee.
The pumps are to be used within the design limits indicated in all
the sales bulletins. Please contact Parker when tresspassing the
catalogue limits.
Do not modify or work on the pump under pressure or when the

electric motor (or any drive) is on.
Qualified personnel is required to assemble and set-up hydraulic

devices.
Always conform yourself to the valid regulations (safety, electrical,

environment...).
The following instructions are important to obtain a good service

life time from the unit.
rotation & ports indication The rotation and ports orientation are viewed from the shaft end.
R = CW stands for clockwise = right-hand rotation.
L = CCW stands for counter-clockwise = left-hand rotation.

Start-up & check-up Check that the assembly of the power unit is correct :
The distance between the suction pipe & the return lines in the
tank should be at its maximum.
A bevel on both suction & return lines is recommended to increase
the surface and so lower the velocity. We suggest a 45° minimum
angle.
Velocities : inlet 0,5 < x < 1,9 m/s (1,64 < x < 6,23 ft per sec.)
: return x < 6 m/s (x < 19,7 ft per sec.)
: Always insure that all return and suction lines are under the
oil level to avoid forming aeration or vortex effect. This
should be done under the most critical situation (all cylin-
ders extended for example). Straight and short pipes are the
best.
Q (Lpm) Q (GPM)
V= 6 x p x r2 (cm) = m/s V = 3.12 x p x r2 (in) = ft/s
The size of the air filter should be 3 times greater than the max.
instant return flow (all cylinders in movement for example).
If the pump is in the tank, please choose the NOP option (no paint)
and use a short inlet pipe.
Parker does not recommend inlet strainers. If needed, a 100 mesh
(149 microns) is the finest mesh recommended.
A coaxial drive is recommended. For any other type of drives,
please contact Parker.
Make sure that all protective plugs & covers have been removed.
Check the pump rotation versus the E-motor or engine rotation.
Start-up : The tank has been filled up with a clean fluid in proper condi-
tions.
We recommend to flush the system with an external pump prior
to the start-up.
It is important to bleed the air off the circuit and the pump itself.

Vierzon - France

Start-up instructions & recommendations Series T7 - T67 - T6, Denison Vane Pumps
The first valve on the circuit should be open to tank.

We recommend the use of air bleed off valves.
It is possible to bleed off the air by creating a leak in the P port
of the pump. Warning : this has to be done in a low pressure
mode as it could create a dangerous fluid leak. Make sure that
the pressure cannot rise (open center valve to tank, pressure
relief valve unloaded ...).
When oil free of air appears, tighten the connectors to the correct
torque.
The pump should prime within a few seconds. If not, please consult
our troubleshooting guide (page 33).
If the pump is noisy, please troubleshoot the system.
Never operate the pump at top speed and pressure without chec-
king the completion of pump priming.
1 . 2 . shaft & coupling data :
COUPLINGS AND FEMALE SPLINES
• The mating female spline should be free to float and find its own
center. If both members are rigidly supported, they must be ali-
gned within 0,15 TIR (0.006” TIR) or less to reduce fretting. The
angular alignment of two splines axes must be less than ± 0,05 per
25,4 radius (± 0.002” per 1” radius).
• The coupling spline must be lubricated with a lithium molydisul-
fide grease, disulfide of molybdenum or a similar lubricant.
• The coupling must be hardened to a hardness between 29 and
45 HRC.
• The female spline must be made to conform to the Class 1 fit as
described in SAE-J498b (1971). This is described as a Flat Root
Side Fit.
keyed shafts Parker supplies the T7 series keyed shaft pumps with high strength
heat-treated keys. Therefore, when installing or replacing these
pumps, the heat-treated keys must be used in order to ensure
maximum life in the application. If the key is replaced, it must be a
heat-treated key between 27 and 34 R.C. hardness. The corners of
the keys must be chamfered by 0,76 mm to 1,02 mm (0.03 to 0.04)
at 45° to clear the radii in the key way.
The alignment of keyed shafts must be within tolerances given for
splined shafts here above.
shaft loads These products are primarily designed for coaxial drives which do
not impose axial or side loading on the shaft. Contact Parker for
specific applications.
1 . 3 . SPECIFIC POINTS :
MINIMUM inlet PRESSURE Please read the charts in the sales leaflets as the minimum reques-
ted inlet pressure varies versus the displacement and the speed.
Never go under 0,8 bar Absolute (-0,2 bar relative)
11.6 PSI Absolute (-2.9 PSI G).
maximum inlet pressure It is recommended to always have at least 1,5 bar (22 PSI) diffe-
rential between inlet and outlet.
Standard shaft seals are limited to 0,7 bar (10 PSI G) but some al-
low 7 bar (100 PSI G). Please contact Parker for more information.
minimum outlet pressure It is recommended to always have at least 1,5 bar (22 PSI) diffe-
rential between inlet and outlet.
VERTICAL MOUNT When assembled vertically, always be careful to prevent any air
from being trapped in the pump (behind the shaft seal for exam-
ple).

1 . 4 . FLUIDS :
denison classification Type of fluids : For each type of fluids, Parker vane pumps will
products have different pressures, speeds & temperature limits.
Please refer to the sales leaflets.
HF-0 = Anti-wear petroleum base.
HF-1 = Non anti-wear petroleum base.
HF-2 = Anti-wear petroleum base.
HF-3 = Water-in-oil invert emulsions.
HF-4 = Water glycol solutions.
HF-5 = Synthetic fluids.
filtration recommendations NAS 1638 class 8 or better.
ISO 19/17/14 or better.
Inlet strainers : Parker does not recommend inlet strainers.

I f requested, a 100 mesh (149 microns) is the finest mesh
recommended.
recommended fluids Petroleum based antiwear R & O fluids.
These fluids are the recommended fluids for pumps & motors.
Maximum catalogue ratings and performance datas are based on
operation with these fluids. These fluids are covered by Parker De-
nison HF-0 and HF-2 specifications.
acceptable alternate fluids The use of fluids other than petroleum based antiwear R & O fluids
requires that the maximum ratings of the pumps will be reduced.
In some cases the minimum replenishment pressures must be in-
creased. Consult specific sections for more details (page 4).

bottom of the tank and therefore limits the ‘’vein flow’’.
c-5) Check if the suction hose is not located near the return line and
therefore sucking a lot of air coming from these turbulences.
c-6) Check if baffles are required to allow correct deareation of the

a-2) Check if seal lip has not been cut during a maintenance operation.
a-3) Check if the inlet pressure is not over or under the catalog
values. This has to be done for the whole cycle because the inlet
pressure can vary from time to time.
a-4) Check if the seal material has not been modified because of
a too warm environment. The seal can vulcanize and stop sealing
correctly.
a-5) Check the acidity of the oil that can «burn» the seals material.
It will therefore destroy the elasticity of the sealing.
a-6) Check if the chosen seal (high pressure seal for example) is
not too stiff for the use. If the environment requires some elasticity
due to a gentle misalignment, a high pressure seal will not be able
to follow the movement and therefore leak.
b) Is the seal b-1) Check the alignment and the correct power transmission (non
destroyed? homokinetic movement, high radial force as examples).
b-2) Check the inlet pressure and compare it to the catalog values.
b-3) Check if the bad suction conditions do not create a vacuum that
could even reverse the seal lip.
b-4) Check if the external environment is not too dirty and therefore
ruining the seal.
