6 2 Technical Information 2-1 Technical Data For applications outside the following parameters, please consult 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 Fluid Selection allowable temperature range 1 6 VG22 VG1 V G68 VG4 6 VG32 kinematic viscosity (cst) Ideal working range Pag. 8

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. Suggested Acceptable 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. Based on the precondition that there is no significant presence of Silica type substances then a minimum cleanliness level of -/18/15 ISO 446 or SAE AS 459E 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 26 bar. Fire-resistant Fluids Some kind of fire-resistant fluids require special materials for seals, paint and metal finishing. Please consult and provide details of the fluid specification and the working conditions ny 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 The following table an overview of the precautions and that can be expected with these types of fluids. Fluid Type Parameter Mineral Oil Polyol Ester Water Glycol Maximum Pressure (bar) Recommended Temperature Range (deg C) 2 ~ 6 2 ~ 6 2 ~ 6 Cavitation susceptability Expected life expectancy compared to mineral oil 1% <1% 2% recommended usable (higher density) Pag. 9

8 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 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). 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. Pag. 1

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 #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.

17 2-7 Installation Pump Mounting Options ain 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. Must be higher than top of Pump Case 2mm minimum depth Fluid level Cautions A) Inlet and drain pipes must be immersed by 2 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 ). 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 measured at the pump casing) as shown in the illustration below. (Peak pressure should never exceed 4 bar.) 4 bar (peak) P.1 sec 1 bar (normal) Mounting the Pump Above the Tank Suction line 2mm minimum depth Fluid level within 1m 2mm minimum depth Pag. 3

18 2-7 Installation (cont) 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.

19 2-7 Installation (cont) ive Shaft Coupling Use a flexible coupling to connect the pump shaft to an engine flywheel or electric motor shaft. Alignment should be within.5 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 for recommendations. Do not force the coupling on or off the pump shaft.
