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- Flow rate: 66 - 6000 m³/h
- Head: 5 - 306 m
- Inlet pressure: < 0.3 MPa
- Inlet and outlet diameter: 150 - 600 mm
- Flange standard: GB/T17241.6, dimensions may vary depending on the
material
- Conveyed medium temperature: Conventional ≤ 80°C, with cooling
structure < 105°C. Special order required when inlet pressure ≥
0.3 MPa or temperature is 105°C or higher.
