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.
