• Product Description
Tobee^® TDG Boiler Feed Water Pump is a horizontal multi-stage centrifugal pump and suitable for transporting pure water (with the contained foreign matters' content less than 1% and graininess less than 0.1mm) or other liquids of both physical and chemical natures similar to pure water. It is applicable to transport medium with temperature of not higher than 105℃ , and high temperature boiler water or transporting medium similar to hot water. If The TDG pumps add a cooling system with specfice shaft seal and materials, It can be used to transport boiler water, hot water, oil, chemicals or corrosive liquids with the temperature of not higher than 210℃.


Design Features:



• Horizontal, Multistage, High pressure, High temperature, Centrifugal pump design
• Stator - Consists of suck-in section, middle-section, spitting section, guide vane, packing etc., which are linked together with a take-up bolt, with both suck-in and spitting mouths vertically upward.
• Rotor - Consists of a shaft, impeller, balancing disk, shaft sleeve etc.
• Bearing - The whole rotor is supported by the roller bearings or sliding bearings on both ends of the shaft and the bearings are lubricate d with grease or 20 engine oil.
• Cooling -  When temperature of the liquid transferred is over 80℃, Cooled water should be filled to the water cooling packing gland and shaft seal cooling chamber. Cooled water and seal water should be clean water in normal degree. The pressure of cooled water should be 1.5-3Kg/cm2, pressure of seal water should be more than 0.5-1Kg/cm2 of the seal chamber.
• Shaft seal - Shaft seals are classified as packing seal and mechanical seal. The water seal wat er of packing seal is industrial water, with pressure of 2-3kg/cm2. The flushing water of mechanical seal is softened water, whose pressure shall be 3kg/cm2 higher than the inlet pressure.
