Reliable, High Pressure and Long Life Design- The K3VG Series Design is based on the K3V MobileSeries Pump where more than 700,000units havebeen supplied to the Construction Machinery Market.The K3VG pump incorporates high load bearings anda friction free contacting mechanism for the pistonshoes. This design has resulted in a pump with highreliability and long service life.2. Low Noise- The unique, compact and rigid housing constructionin addition to the semi-cylindrical pillow type swashplate and its anti-vibration supporting mechanism hassignificantly reduced noise levels.3. High Efficiency and High Self-Priming CapabilityFeaturesReliable, High Pressure, Long Life Modular Design.Low Noise and High Efficiency.Self-Compensating piston return mechanism.- K3VG Pumps encompass a spherical shaped valveplate design and improved hydraulic balancing whichprovide stable cylinder rotation, thus achieving highefficiency even in low-pressure, low-speed operatingconditions. The spherical shaped valve plate alsoenables a shortened radius of the cylinder ports, whichreduces the peripheral velocity and pressure-drop.Extensive Range of Highly Responsive Control Options.Auxiliary Gear Pump Option.Rated Pressure 350 Bar.Peak Pressure 400 Bar.This feature significantly improves the self-primingcapability of the pump.4. Extensive Range of Control Options- A large variety of hydromechanical and hydroelectriccontrol methods are available. Displacement, pressurecutoff, horsepower control, and various combinationsof these controls are available.High Continuous Power Rating.Fully Balanced Spherical Valve Plate.Infinite displacement control.Hydrostatically Balanced Swash Plate Support.5. Auxiliary Gear Pump- Various sizes of optional gear pumps can be provided.High Load Capacity Bearings.Therefore, no separate pump unit is necessary as acontrol pressure source or system medium-pressuresource and possible to attach high pressure gear pump.Hydraulic units can thus be made compact and moreeconomical.7

K3VG PUMPS2-1 Technical Data (cont)Filtration & ContaminationControlFiltrationThe most important means to prevent prematuredamage to the pump and associated equipment andto extend its working life, is to ensure that hydraulicfluid contamination control of the system is workingeffectively.Working Fluid TypesAnti-Wear Type Hydraulic fluidIt is generally recommended to use an anti-wearhydraulic fluid like mineral oil when the operatingpressure exceeds 210 bar.Fire-resistant FluidsSome kind of fire-resistant fluids require specialmaterials for seals, paint and metal finishing. PleaseThis begins by ensuring that at the time of installationconsult KPM and provide details of the particular fluidthat all piping, tanks etc. are rigorously cleaned in aspecification and the working conditions so that anysanitary way. Flushing should be provided using anspecial requirements can be ascertained.off line filtration system and after flushing the filterelements should be replaced.In general, fire-resistant fluids have a low viscosityindex and their viscosity also changes significantly withA full flow return line filter of 10 micron nominaloperating temperature and service life. For this reason,should be utilised to prevent contaminant ingress fromthe circuit should be provided with an adequatelythe external environment, a 5 to 10 micron filter withinsized cooler or forced cooling so that temperaturesthe tank’s breather is also recommended.can be stabilised. Due to the inherent water contentof some of these fluids the minimum allowable suctionSuggested AcceptableContamination Levelpressure will be higher than that of an equivalentmineral oil and so needs to be fully evaluated byKPM. The following table provides an overview of theprecautions and characteristics that can be expectedThe relationship between contamination level andwith these types of fluids.pump life is very difficult to predict as it depends onthe type and nature of the contaminant present in thesystem.

K3VG PUMPS2-1 Technical Data (cont)Pump Start Up PrecautionsPump Case FillingBe sure to fill the pump casing with oil through the drain port, filling only the suction line with oil is totally insufficient. The pump contains bearings and high-speed sliding parts including pistons with shoes and sphericalbushes that need to be continuously lubricated. Part seizure or total premature failure will occur very quickly ifthis procedure is not rigidly followed.Piping & Circuit CheckingCheck to see that the piping and full hydraulic circuit is completed and that any gate valves etc. are open.Direction of RotationCheck to ensure that direction of rotation is correct and that the inlet and delivery lines are connected correctly.Start UpJog start the motor and check once more for correct rotation. Run the pump unloaded for a period to ensure thatall residual air within the system is released. Check for external leakage, abnormal noise and vibrations.Case Drain PressurePlease 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 tankand terminate below the oil level.Long Term Out of UsageIt is undesirable to leave the pump out of use for a long period e.g. a year or more. In such a situation it isrecommended that the pump is run for a short period on a more frequent basis even if it is just unloaded. Withregard to a pump held in storage then rotating the shaft on a frequent basis is sufficient. If the pump is left out formore than the suggested time it will require a service inspection.12
