2 General information KM Handled Liquids : KM pumps are suitable for clean liquids with low viscosity. Technical ata ischarge Nozzle Range Capacities Heads N 65 up to mm up to 700 m3/h up to 560 m esign Feature Horizontal ring section multistage centrifugal pumps with closed impellers and diffusers. 6 models from N 65 to N. peed Operating Temperature Casing Pressure (Pmax) Applications rpm 10 oc up to 110oC * 30 bar (60 bar)* (Pmax : uction Pressure + hut off Head) (*) The material of pumps differ according to the type of pumped liquid, operating temperature and pressure. Contact our company for detailed information. uction nozzle flanges are according to IN 2533 / PN 16 and discharge nozzle flanges are according to IN 2535 / PN 40 (IN 2546 / PN 64). In standart production suction flange is placed on the right side and close to the coupling and discharge flange is at the other end and at top. uction and discharge nozzle can be turned in multiples of 90o. General water supply Municipal water supply Pressurized water supply Boosters systems Boiler feed water and condensate Heating and air conditioning Irrigation, sprinkler Circulation Industry Fire fighting systems Power plants. Axial thrust is balanced by balancing disc. In standard production coupling is on the suction side and direction of rotation is clockwise viewed from driver end. driven from the discharge side can be manufactured on special request. In this case direction of rotation is counter clockwise viewed from the driver end. shaft is supported by grease lubricated NU type roller bearings. impellers are statically and dynamically balanced. esignation KM / 9 type ischarge nozzle (N) Number of stages
