QM85-45 Multistage Pump Model QM(G) pump is horizontal multistage centrifugal pump and suiatble for transfering pure water (with the contained freign matter's content less than 1% and graininess less than 0.1mm), and other liquids of both physical and chemical natures similar to those of pure water. Model QMG middle and low pressure boiler water supply pump, is applied to transport medium with temperature of not higher than 105 degree centigrade, and is also applicable for small boiler water supply or transporting medium similar to hotwater. Peformance of QM multistage pump. Flow: 3.75 - 185 m3/h Head: 69 - 684 m Inlet diameters: 40 - 150 mm QMG series hypo-high-pressure boiler water supply pump is applicable to transport medium with temperature of not higher than 160 degree centigrade, and is also applicable for small boiler water supply or transporting medium similar to hot water. Performance range of model QMG series Flow: 15 -300 m3/h Head: 390 - 1050 m Corollary power: 75 - 1250 kw Inlet diamter: 65 - 200 Model Meaning eg: QM 6-25 QM : centrifugal multistage stage pump 6: flowrate (m3/h) 25: single stage head (m)
