6 2 Technical Information 2-1 Technical Data For applications outside the following parameters, please consult KPM UK. Hydraulic Data Pressure Fluid Mineral oil, polyol ester and water glycol. Use a high quality, anti-wear, mineral based hydraulic fluid when the pressure exceeds 26 bar. In applications where fire resistant fluids are required consult KPM UK. Fluid selection allowable temperature range 1 6 VG22 VG1 VG68 VG46 VG32 kinematic viscosity (cst) Ideal working range fluid temperature ( C) 5

7 2-1 Technical Data (cont) Filtration & Contamination Control 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. full flow return line filter of 1 micron nominal should be utilised to prevent contaminant ingress from the external environment, a 5 to 1 micron filter within the tank s breather is also recommended. Suggested cceptable Contamination Level 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. ased on the precondition that there is no significant presence of Silica type substances then a minimum Cleanliness level of -/18/15 ISO 446 or SE S 459E Table 1 Class 9 (NS 1638 Class 9 ). Working Fluid Types nti-wear Type Hydraulic fluid It is generally recommended to use an anti-wear hydraulic fluid like mineral oil when the operating pressure exceeds 26 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. Fluid Type Parameter Maximum Pressure (bar) Recommended Temperature Range (deg C) Mineral Oil Polyol Ester Water Glycol ~ 6 2 ~ 6 2 ~ 6 Cavitation susceptability Expected life expectancy compared to mineral oil 1% <1% 2% recommended usable (higher density) 6

8 2-1 Technical Data (cont) Pump Start Up Precautions Pump Case Filling e 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 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 ain 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). 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. 7

11 2-2 Specifications (cont) #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 llowable 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. Notes: Rated Pressure Pressure at which life and durability will not be affected. Peak Pressure The instant allowable surge pressure as defined by S ISO 2944:2.

Maximum oosted Speed Values stated are the absolute maximum permitted speed for which an increased inlet pressure will be required. Weight pproximate dry weights, dependant on exact pump type.

Do not connect the drain line to the inlet line. Cautions Must be higher than top of Pump Case 2mm minimum depth Fluid level ) Inlet and drain pipes must be immersed by 2 mm minimum from the lowest level under operating conditions. ) 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. The uppermost drain port should be used and the drain piping should be equal or larger in size than the drain port to minimise pressure in the pump case. The pump case pressure should not exceed 1 bar as shown in the illustration below.

For applications requiring vertical installation (shaft up) please remove the 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 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 bleed port 1 ~ 2 l/min. When installing the pump outside the tank run piping for the drain and bleed ports to tank (see illustration [c]).
