Customizable High-Pressure Electric Horizontal Centrifugal Water Pump for Industrial Use-OEM Boiler Feed Irrigation Agriculture

A boiler feed pump is a critical component of a boiler system that ensures a reliable and continuous water supply to the boiler for steam generation. This pump is specifically designed to deliver water to the boiler at high pressures and temperatures, meeting the demanding requirements of industrial and commercial applications. Let's take a brief look at the key features and functions of a boiler feed pump.

PRODUCT PURPOSE

Model CG-D 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) and other liquids of both physical and chemical natures similar to those of pure water.

CG-D model middle and low pressure boiler water supply pump is applicable to transport medium with temperature of not higher than 105, and is also applicable for

small boiler water supply or transporting medium similar to hot water. 

Performance range of model CGD series

Flow: 3.75~185m/h

Corollary power: 4.0~400kW

Head: 69~684m

Inlet diameter: 40~150mm

CG-D model hypo-high-pressure boiler water supply pump is applicable to transport medium with temperature of not higher than 160, and is also applicable for small

boiler water supply or transporting medium similar to hot water. 

Performance range of model CGD series

Flow: 15~300m/h

Corollary power: 75~1250kW

Head: 390~1050m

Inlet diameter: 65~200mm

ABOUT THESTABOUT THESTRUCTURERUCTU

For this series horizontal multi-stage centrifugal pump,both ends of it are supported,the casing portion is in a sectional form,it is connected to and actuated by a motor via

are silent clutch and the rotating direction of it,viewing from the actuating end, is clockwise.Refer to Fig.1 for the structure of it.

Stator portion 

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 portion 

Consists of a shaft,impeller,balancing disk,muff etc.parts.

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 20engin oil.

Cooling and seal of pump

The joint-part between suction section, intermediate section and discharge section with be coated with molybdenum disulfide lubricating grease as seal. Rotor and fixed parts

will be sealed by seal ring,guide-vane jacket and packing.The packing tensile degree of shaft seal should be proper and seep should be feasible dip by dip Unload run should be forbid.

The seal ring and guide vane jacket should be replaced if they are too worn to be used any more and even do harm to pump work. There is spare shaft sleeve near shaft seal to protect

shaft of pump. The shaft seal should perform to hold water and seal water.When temperature of the liquid transferred is above 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 0.5~1 Kg/cm of the seal chamber.The positions of cooling water pipe joints are different for various kind of water pump. Please refer to construction drawing of pump

for axial position,and refer to chart 1for radial position. Shaft seals are class ifiedas packing sea land mechanical seal.The water seal water of packing seal is industrial water, with pressure

of 23kg/cm. The flushing water of mechanical seal is softened water, whose pressure shall be 3kg/cm higher than the inlet pressure.
