High-Efficiency East Dfss Double Suction Industrial Booster Pump

Impeller

• Selects an industry - leading excellent hydraulic model, featuring high efficiency and low cavitation.
• The impeller has a double - suction, symmetrical structure to minimize axial thrust.
• Multiple impellers can be matched with one casing to meet different operating conditions.

Seal Ring

• Designed with an enlarged structure to reduce leakage between high - and low - pressure areas and minimize volumetric losses.
• Multiple material configurations are available to extend the service life of components.

Shaft

• High rigidity, small deflection, and low vibration.
• It has a fully - enclosed design with a replaceable wear - resistant shaft sleeve to protect the shaft from contact with the medium, preventing corrosion.

Bearing Assembly

• Different lubrication methods (grease or oil lubrication) are used according to the characteristics of different shaft systems.
• Imported bearings can be selected to meet different operating conditions.
• When transporting high - temperature media, external cooling water can be connected for forced cooling.

Sealing Components

• High - quality mechanical seals (cartridge - type mechanical seals are available) are used, with no leakage and reliable operation.
• High - quality packing seals can be selected according to the application scenario for easier replacement.
• When transporting high - temperature media, external flushing or additional heat exchangers can be used to cool the seal chamber.

Pump Casing

• The single - volute suction chamber reduces inlet turbulence and improves anti - cavitation performance.
• For high - head and large - flow models, a double - volute design is adopted to effectively balance radial force.

High - efficiency and Energy - saving

• The hydraulic model is optimized through CFD (Computational Fluid Dynamics) numerical simulation. The impeller and the pump casing are highly matched, resulting in low flow losses.
• For flow - passage components, various manufacturing methods such as resin - sand casting, lost - foam casting, and precision casting are employed. This ensures accurate dimensions and smooth surfaces of the flow - passage components, achieving the high - efficiency operation of the water pump.

Operating Conditions
