Description

DG Type Boiler Water Supply Pump is a horizontal multi-stage centrifugal pump and suitable to transport pure water (with contained foreign matters&#**9; content less than 1% and grainiess less than 0.1mm) and other liquids of both physical and chemical natures similar to those of pure water. DG model middle and low pressure boiler water supply pump is applicalbe to transport medium with temperature of not higher than **5 centigrade, and is also applicable for small boiler water supply or transporting medium similar to hot water. Performance range of model DG Boiler Water Supply Pump: Flow:3.*****5 cubic meter/hour; Corollary Power: 4.****0KW; Head:*****4M; Inlet Diameter:*****0 mm. DG model hypo-high -pressure boiler water supply pump is applicable to transport medium with temperature of not higher than **0 centigrade, and is also applicable for small boiler water supply or transporting medium similar to hot water. Performance range of Hypo-high-pressure Boiler Water Supply Pump: Flow:*****0 cubic meter/hour; Corollary Power:******0KW; Head:*******0M; Inlet Diameter:*****0mm. Construction Discription: 1. For this series horizontal multi-stage centrifugal pump, both ends are supported, the casing portion is in a sectional form, it is connected to and actuated by a motor via a resilient clutch. 2.Stator portion: Consists of suck-in section, middle-section, spitting section, guide vane, packing, which are linked together with a take-up bolt, with both suck-in and spitting mouths vertically upward. ***** Portion: Consists of a shaft, impeller, balancing disk, muff and other parts. 4.Bearing Portion: The whole rotor is supported by the roller bearings or sliding bearings on both ends of the shaft and the bearings are lubricated with grease or NO.*0 engin oil. ***** and Seal: The joint-part between suction section, intermediate section and discharge section will be coated with molybdenum disulfide lubricating greaase as seal.
