Handling Precautions

1. Operating Fluid and Temperature Range

1) Operating Fluid

Values shown in this catalog are based upon usingmineral oil based anti-wear hydraulic fluid. Toensure optimal performance use of mineral oilbased anti-wear hydraulic fluid is recommended.

2) Viscosity and temperature range

To minimize both oil and seal deterioration, amaximum operating temperature of 60°C shouldbe considered. Please note that the regulatormay become slow to respond when operatingat low temperatures (below 20°C) in extremecold environments. At such low temperature itis strongly suggested that a warm up cycle isintroduced until an operating temperature of 20°Cis achieved.

Normal operatingrange

Allowable range

Viscosity [mm2/s(cSt)] 10 to 200 10 to 1,000

Fluid temperature [°C (°F)]

-20 to +80 (-4 to +176)

2. Filtration and Contamination Control

1) Filtration of working oil

The most important means to prevent prematuredamage to the pump and associated equipmentand to extend its working life, is to ensure thathydraulic fluid contamination control of the systemis working effectively.

This begins by ensuring that at the time ofinstallation that all piping, tanks etc. are rigorouslycleaned in a sanitary way. Flushing should beprovided using an off line filtration systemand after flushing the filter elements should bereplaced.

2) Suggested acceptable contamination level

The relationship between contamination level andpump life is very difficult to predict as it dependson the type and nature of the contaminant presentin the system. Sand or Silica in particular, due toits abrasive nature, does significantly reduce theexpected life of a pump. Based on the preconditionthat there is no significant presence of Silica typesubstances then a minimum Cleanliness level of-/18/15 ISO 4406 or SAE AS 4059E Table 1 Class 9(NAS 1638 Class 9).

3. Drive Shaft CouplingAlignment between the prime mover and the pump shaft should be within 0.05 mm TIR*. In case the pump is

directly coupled to the engine flywheel, use a flexible coupling.

4. Oil Filling and Air Bleeding

5. Earthing

Be sure to fill the pump casing with 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 a

spherical bush that need to be continuously lubricated. Part seizure or total premature failure will occur

very quickly if this procedure is not rIgidly followed.

It is the end users responsibility to ensure that for use in

explosive atmospheres the K3VL is earthed. A suitable

earthing point would be the eye bolt position.

1) Pump case filling

Run the pump unloaded for a period to ensure that all residual air within the system is released.

2) Air bleeding

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.

3) Long term out of usage

Page 7: Swash-plate Type Axial Piston Pump K3VL Series

6. Drain Piping

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.

1) Installation of drain 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.

C) The oil in the pump case must be refilled when

the pump has not been operated for one month

or longer.

The uppermost drain port should be used and the drain piping must be larger in size than the drain port

to minimise pressure in the pump case. The pump case pressure must not exceed 1 bar as shown in the

illustration below. (Peak pressure must never exceed 4 bar.)

4 bar(peak)

1 bar(normal)

0.1 sec

P

The internal bore size of the drain hose or drain pipe must be larger than that of the drain port. Arrange the

drain line as short as possible.

2) Size of drain hose or drain pipe

7. Mounting the Pump Above the Tank

Suction line.

Page 8: Swash-plate Type Axial Piston Pump K3VL Series

8. 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]. If required pumps can be supplied unpainted to avoid

the risk of contaminating fluid. Please contact KPMUK.

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.

If the drain or Tair bleed piping rise above the level of oil (see illustration [B]). Fill the lines with oil before operation, then

confirm pump case pressure is within specification during commissioning. When installing the pump outside the tank, run

piping for the drain and Tair bleed ports to tank (see illustration [C])

10. Maintenance Schedule

11. Warning

Although K3VL pumps are equipped with bearings that can accept some external thrust and radial forces,

application of such loads will affect bearing life. Depending on the load magnitude , the load position, and

the load orientation, bearing life may be significantly reduced.

To prevent malfunction the bearing should be replaced at regular intervals based on pump duty. See page.... for

predicted bearing life.

System must be fitted with an Atex approved temperature sensor and cut out switch such that in catastrophic

failure power unit is shut down. (Fitted by customer).

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.

2-2 Technical Data (cont)

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 210 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.

Pump Start Up Precuations

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.

End of Life

The pump unit, hydraulic fluid and packaging must be disposed

of carefully to avoid pollution to the environment. The pump

unit must be completely empty upon disposal, it must be

disposed of according to national regulations and you must

also follow safety information for disposal of the hydraulic

fluid.

All individual parts of the pump unit must be recycled. Separate

the pump unit parts according to: cast parts, steel, aluminium,

non-ferrous metal, electronic waste, plastic, and seals.

2-4 Bearing life calculation

The graphs below show the expected L10 life of the K3VL pump bearings.

These graphs are to be used to by the system designer to calculate a regular maintenance and overhaul schedule.

The graphs show theoretical bearing lives and do not consider adjustment factors, for example:- fluid cleanliness “x”, fluid

temperature “x” and fluid quality “x”. It is the system designer’s responsibility to apply adjustment factors to the L10 bearing

lives shown within the graphs in order to establish the required actual maintenance and overhaul schedules.

eg. L10 10000 hrs multiplied by adjustment factor “x” multiplied by adjustment factor “x” and so on……

Please note: These bearing lives relate to mineral oil only. Please see page 18 for Water Glycol adjustment factor.

No axial shaft loading posible, radial loading is achievable but in specific orientation:-

Radial shaft loading can be allowed provided that its orientation is such that the front bearing takes the additional

load (see diagram below).

Note: In this case bearing life will be reduced.

L0/L1 Load Sense and Pressure Cut-off

Pump displacement is controlled to match the flow requirement as a

function of the system differential pressure (load pressure vs delivery

pressure). In addition, there is a pressure cut off function

incorporated into the control with the L1 option, the bleed-off orifice

R4 is plugged.

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.

However if a pilot pressure is applied to the Pf 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% .

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.

P0/1 control functions aspreviously noted. In responseto a rise in delivery pressure

the swashplate angle is reduced,restricting the input torque. This

regulator prevents excessive loadagainst the prime mover.

Note: By connecting the Pc port toa remote pressure control, variable

pump pressure control canbe achieved.

/1-Q0 Pilot OperatedDisplacement Control

Varying the input pressure signal tothe Pi port allows the user to control

the pump displacement. As thepressure signal to the Pi increases,

the pump displacementincreases proportionally.

Note: A variable external pressure supply of

up to 40 bar is required at the PiPort (50 bar max).

Through Drive Limitations (cont)

Apart 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
