4 1.3.3 Hydraulic Fluids The pump series is prepared for HLP Mineral Oil Before using other fluids, please contact HYDAC: HEES, HETG Environmental Friendly Hydraulic Fluids HFC Water Glycol HFD-U Polyol Ester Fire Resistant Fluids HFD-R Phosphate Ester Fire Resistant Fluids Viscosity Range cst (mm 2 /s) Minimal viscosity: 10 Normal operating viscosity: Maximal viscosity: Temperature Range Operating temperature range -20 up to 100 C Maximum ambient temperature range -40 up to 80 C Maximum fluid temperature range -40 up to 120 C Seals The pump series is equipped with FKM- (Viton-) seals. Please contact HYDAC before using synthetic fluids Filtration For maximum pump and system component life time, the system should be protected from contamination by effective filtration. Maintain the degree of contamination within 20/ 18/ 15 per ISO 4406:1999 or Grade 9 per NAS 1638 In order to ensure a longer operating lifetime, the contamination should be better then 18/16/13 per ISO 4406:1999 or Grade 7 per NAS Installation Notes A. Mounting The pump can be mounted in horizontal direction or vertical with the shaft upwards. If the pump is installed on the tank or at a position higher than the tank top cover, the height of the suction port of the pump should be less then 1 metre from the oil level. B. Suction Line When the pump is installed over the tank oil level, it is recommended to pay attention to the inlet pressure. The minimum section of the inlet pipe must be equal or larger to the section of the inlet port of the pump. The suction pressure must be within the specified values. Minimum suction pressure: 0.8 bar abs. Maximum suction pressure: 2.0 bar abs. C. Drive Employ a flexible coupling whenever possible. Radial or axial loads on the pump shaft are not allowed. The maximum radial runout of the shaft is less than 0.2 mm and the angular displacement has to be within Multiple Pumps The Internal Gear Pumps of the PGI102-Series can be combined to double or triple units (for larger units please contact HYDAC). Generally, the specifications for the single pumps apply, but the following notes should be observed: It is recommended to position the pump with the largest load on the drive side The max. speed of the multiple pump unit is determined by the pump rated with the lowest speed The maximum input torque and through drive torques must be verified for each application. The resulting torque of the pump combination can be calculated by the following formula: M max = p 1 V 1 + p 2 V 2 + p 3 V 3 20 π η mh 20 π η mh 20 π η mh Admissible Input and Through Drive Torques Framesize Input Torque Through Drive Torque Rated Peak Rated Peak Nm 200 Nm 120 Nm 130 Nm Nm 400 Nm 230 Nm 240 Nm Nm 1300 Nm 850 Nm 900 Nm One common suction port, separate pressure ports. The pumps are not sealed from each other. Combinations of PGI101 and PGI102 are possible 64
