Filtration & ContaminationControl
Suggested AcceptableContamination Level
Filtration
The most important means to prevent premature
damage to the pump and associated equipment and
to extend its working life, is to ensure that hydraulic
fluid contamination control of the system is working
effectively.
This begins by ensuring that at the time of
installation that all piping, tanks etc. are rigorously
cleaned in a sanitary way. Flushing should be
provided using an off line filtration system and after
flushing the filter elements should be replaced.
The relationship between contamination level and
pump life is very difficult to predict as it depends on
the type and nature of the contaminant present in the
system. Sand or Silica in particular, due to its abrasive
nature, does significantly reduce the expected life of
a pump. Based on the precondition that there is no
significant presence of Silica type substances then a
minimum cleanliness level of -/18/15 ISO 4406 or
SAE AS 4059E Table 1 Class 9 (NAS 1638 Class 9 ).
Working Fluid Types
Anti-Wear Type Hydraulic fluid
It is generally recommended to use an anti-wear
hydraulic fluid like mineral oil when the operating
pressure exceeds 206 bar.
Fire-resistant Fluids
Some kind of fire-resistant fluids require special
materials for seals, paint and metal finishing. Please
consult KPM UK and provide details of the particular
fluid specification and the working conditions so that
any special requirements can be ascertained.
In general, fire-resistant fluids have a low viscosity
index and their viscosity also changes significantly
with operating temperature and service life. For
this reason, the circuit should be provided with an
adequately sized cooler or forced cooling so that
temperatures can be stabilised. Due to the inherent
water content of some of these fluids the minimum
allowable suction pressure will be higher than that
of an equivalent mineral oil and so needs to be fully
evaluated by KPM UK. The following table provides
an overview of the precautions and characteristics
that can be expected with these types of fluids.

2-1 Technical Data (cont)
Pump Start Up Precuations
Pump Case Filling
Be sure to fill the pump casing with clean hydraulic oil through the drain port, filling only the suction line with oil
is totally in sufficient. The pump contains bearings and high-speed sliding parts including pistons with shoes and
spherical bushes that need to be continuously lubricated. Part seizure or total premature failure will occur very
quickly if this procedure is not rigidly followed.
Piping & Circuit Checking
Check to see that the piping and full hydraulic circuit is completed and that any gate valves etc. are open.
Direction of Rotation
Check to ensure that direction of rotation is correct and that the inlet and delivery lines are connected correctly.
Start Up
Jog start the motor and check once more for correct rotation. Run the pump unloaded for a period to ensure that
all residual air within the system is released. Check for external leakage, abnormal noise and vibrations.
Case Drain Pressure
Please ensure, that the maximum steady state drain line pressure at the pump casing does not exceed 1 bar.
(Maximum peak pressure 4 bar). A suitable drain line hose must be selected and return directly back to the tank
and terminate below the oil level.
Long Term Out of Usage
It is undesirable to leave the pump out of use for a long period e.g. a year or more. In such a situation it is
recommended that the pump is run for a short period on a more frequent basis even if it is just unloaded. With
regard to a pump held in storage then rotating the shaft on a frequent basis is sufficient. If the pump is left out for
more than the suggested time it will require a service inspection.

Note:
The shaft surface will have a finite life due to wear unless adequate lubrication is provided.
#1 Maximum allowable shaft torques are based on achieving an infinite life for a coupling assembly that is
lubricated and completely clamped and utilises the full spline/key length as engagement.
The following points therefore need to be fully considered:-
i) Lubrication of shaft couplings should be in accordance with the coupling manufacturers instructions.
ii) The maximum allowable input shaft torque is based on ensuring an infinite life condition by limiting the
resultant combined shaft bending and torsional stress.
iii) This allowable input shaft torque can be further increased dependant on the resultant surface stress at the
spline interface which is highly dependant on coupling selection and the provision of adequate spline lubrication.
If you have an application that requires higher input torque please consult KPM UK.
#2 Allowable through drive torques are based on the achieving an infinite life for a fully lubricated coupling
and full spline engagement with a mineral oil based anti-wear hydraulic fluid.

L0/1 Load Sense and PressureCut-off with Torque Limiting
L0/L1 control functions aspreviously noted. In response toa rise in delivery pressure theswashplate angle is decreased,
restricting the input torque. Thisregulator prevents excessive load
against the prime mover.The torque limit control moduleis comprised of two springs that
oppose the spool force generated bythe system pressure. By turning anouter and inner spring adjustment
screw, the appropriate input torquelimit can be set.

/2-** Hydraulic Power Shiftwith Load Sensing
This function, as with the /1 type can be used with Pressure compensation, Load sense and
additional control options such as unloader functions. The control
has the same function as standard torque limit option. In response to a rise in delivery pressure
the swashplate angle is reduced, restricting input torque. Howev-er if a pilot pressure is applied to the Pi port on the regulator,
the torque setting can be further reduced proportionally to the pilot
pressure applied. The input torque can be reduced
by approximately 40% .
/3-** Electronic Power Shift with Load Sensing
This function, as with the /1 type can be used with Pressure compensation, Load sense and
additional control options such as unloader functions. The control
has the same function as standard torque limit. In response to a rise in delivery pressure the swash-
plate angle is reduced, restricting input torque. However a pilot pressure of 40 bar is required,
applied to the Pi port of the reg-ulator. The torque setting can be further reduced proportionally to a 24VDC electrical signal applied to the proportional valve on the
regulator.
P0 Pressure Cut-off
As system pressure rises to the cutoff setting, the swashplate
de-strokes to prevent the system pressure from exceeding the
compensator setting. It is imperative that a safety relief
valve be installed in the system.
Note: By connecting the Pc port toa remote pressure control,
variable pump pressure control can be achieved.

Drain line
It is the preferred option to mount the pump with the case drain piping initially rising above the pump before
continuing to the tank. Do not connect the drain line to the inlet line.
Cautions
A) Inlet and drain pipes must be immersed by
200 mm minimum from the lowest level under
operating conditions.
B) Height from the oil level to the centre of the shaft
must be within 1 meter maximum. (consult KPM UK).
C) The oil in the pump case must be refilled when
the pump has not been operated for one month
or longer.

Mounting the Pump Vertically (shaft up)
Note: Both the Tair and one case drain port must be used.
For applications requiring vertical installation (shaft up) please remove the Tair bleed plug and connect piping as
shown in the illustration below.
When installing the pump in the tank and submerged in the oil, open the drain port and Tair bleed port to provide
adequate lubrication to the internal components. See illustration [a].
The oil level in the tank should be higher than the pump-mounting flange as shown in illustration [a] below. If the
oil level in the tank is lower than the pump mounting flange then forced lubrication is required through the Tair
bleed port 1 ~ 2 l/min.
When installing the pump outside the tank run piping for the drain and Tair bleed ports to tank (see illustration
[c]). If the drain or Tair bleed piping rise above the level of oil (see illustration [b]) fill the lines with oil before
operation.motor to your national standard is not exceeded.

Use a flexible coupling to connect the pump shaft to an engine flywheel or electric motor shaft. Alignment should
be within 0.05 mm TIR as shown in the illustration below.
Do not apply any radial or axial loading to the pump shaft. For applications where radial or side loads exist please
contact KPM UK for recommendations.
Do not force the coupling on or off the pump shaft. Use the threaded hole in the end of the pump shaft to fix or
remove the coupling.

Through Drive LimitationsApart from predefined maximum throughput limitations, one must also ensure that to prevent a possible
excessive bending moment occurring that the maximum combined bending moment of the combination
is not exceeded as determined in the following expression.
MPX = mass of pump [kg]
LPX = length of pump [mm]
Lx = distance of CofG from pump mounting face [mm]
MAX = mass of adaptor kit [kg]
LAX = width of adaptor kit [mm]
Bending Moment = ((L1.mP1) + (LA1’.mA1) + (LP2’.mP2) +(LA2’.mA2) +LP3’.mP3) +…)/102[Nm] ((L1.mP1) + (LP1+(LA1/2)).mA1 + (LP1+LA1+L2).mP2 + (LP1+LA1+LP2(LA2/2)).mA2) + (LP1+LA1+LP2+LA2).mP3) +……)/102

2-7 Installation (cont)
Electrical and Pilot Operated Displacement Control (Type E0, E1, E2, E3 & Q0)
Type E0 - In order for the electronic displacement control to function, a pilot pressure of 40 bar must be
supplied to the Pi port on the regulator. A gear pump attached to the rear of the K3VL pump or an external
pressure source can be used to provide the required pilot pressure.
Type Q0 - In order for the Q0 displacement control to function, a variable pilot pressure between 0 and 40 bar
is requiredto be supplied to the Pi port on the regulator.
Proportional Pressure Reducing Valve Specification
Maximum Pilot Pressure : 50 bar (if higher pressure
required contact KPM UK)
Max Flow: : 10 l/min
Hydraulic oil : Mineral oil
Oil temp range : -20~+900C
Viscosity range : 5~500 cSt
