Welcome to a revolutionary solution for your water supply needs—the Single-Suction Horizontal Multistage Boiler Feed Centrifugal Pump. Engineered for efficiency and reliability,

this pump is tailored to meet the rigorous demands of boiler feed applications, ensuring a steady and precise water supply for industrial processes.

Explore the features and advantages below to understand why this pump is the perfect choice for enhancing your water supply system.

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. 

Key Features:

Robust Construction: The Horizontal Boiler Feed Pump is built with high-quality materials to ensure longevity and reliability in demanding industrial environments.

Efficient Performance: Equipped with a powerful motor, this pump delivers a consistent and high-pressure flow of water, ideal for boiler feed systems.

Horizontal Design: The horizontal configuration of the pump allows for easy installation and maintenance, making it a practical choice for industrial settings.

Precise Control: This pump offers precise control over water flow and pressure, essential for maintaining optimal boiler operation.

Energy Efficiency: Designed to operate efficiently, the Horizontal Boiler Feed Pump helps reduce energy costs while maintaining high performance levels.

Applications:

Boiler Feed Systems: Ensures a steady supply of water to boilers for optimal operation and efficiency.

Industrial Processes: Suitable for various industrial applications requiring precise water flow and pressure control.

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 a suck-in section, middle section, spitting section, guide vane, and packing, all linked together with a take-up bolt. Both the suck-in and spitting mouths are vertically upward.

Rotor Portion

Includes a shaft, impeller, balancing disk, muff, and other parts.

Bearing Portion

The entire rotor is supported by roller bearings or sliding bearings at both ends of the shaft, lubricated with grease or 20 engine oil.

Cooling and Seal of the Pump

The joints between the suction section, intermediate section, and discharge section are coated with molybdenum disulfide lubricating grease as a seal.

The rotor and fixed parts are sealed by a seal ring, guide-vane jacket, and packing. The packing tension of the shaft seal should be appropriate, allowing

for feasible dip-by-dip seepage. Unloaded runs should be avoided.

The seal ring and guide vane jacket should be replaced if worn out to prevent damage to the pump. A spare shaft sleeve near the shaft seal protects the

pump shaft. The shaft seal should hold and seal water effectively. When the transferred liquid's temperature exceeds 80℃, cooled water should be filled

into the water cooling packing gland and shaft seal cooling chamber. 

Cooled water and seal water should be clean and at normal temperature. The pressure of cooled water should be 1.5-3 kg/cm², and the pressure of

seal water should be more than 0.5-1 kg/cm² of the seal chamber. The cooling water pipe joints' positions vary with different pumps. Refer to the construction

drawing of the pump for axial positions and chart 1 for radial positions. Shaft seals are classified as packing seals and mechanical seals.

The packing seal water is industrial water with a pressure of 2-3 kg/cm². The mechanical seal's flushing water is softened water, with a pressure 3 kg/cm² higher than the inlet pressure.
