1.Impeller

Adopts an excellent hydraulic model and is manufactured by welding.
Arranged back - to - back to balance axial thrust.
The impeller ring and inlet are painted with anti - rust paint.

2.Casing Seal Ring

Special structure for anti - erosion and anti - leakage.

3.Shaft

Large diameter meets the requirements of dynamic characteristics and torque transmission.
Step - shaft design for easy disassembly and assembly.

4.Bearing Isolator

Easy to install with no leakage.

5.Bearing Assembly

For large pumps: a combination of high - load rolling bearings and sliding bearings.
For small pumps: a combination of rolling bearings.

6.Throttle Bush

Special structure for anti - erosion and anti - leakage.

7.Pump Casing

Optimized by CFD analysis.
Double - suction ports, strong anti - cavitation performance.
Double - volute casing discharge chamber to balance radial force.
Symmetrical transition flow passage to balance radial force.

Operating Range

Flow rate: 300 - 10800 m³/h
Head: 81 - 340 m
Inlet pressure: ≤ 0.6 MPa
Medium temperature: -20°C - 80°C

High - efficiency and Energy - saving

01.The pump body, pump cover, and impeller adopt excellent hydraulic models and are optimized through CFD design. The pump casing is made by resin - sand molding, ensuring accurate dimensions and smooth surfaces of the flow channels, thus improving the hydraulic efficiency of the pump.

02.For pump bodies and pump covers of different sizes and materials, the optimal casting process is adopted to ensure accurate dimensions and smooth surfaces of the flow channels, minimizing hydraulic losses. The standard - equipped impeller is a welded impeller, which offers higher dimensional accuracy, geometric precision, and a longer service life.

01.The first - stage and intermediate - stage impellers are arranged in a back - to - back structure of single - suction impellers. This can effectively balance the axial force generated by the pressure difference on the front and rear sides of the rear cover plate at the suction port of a single - suction impeller. The last - stage impeller is a double - suction impeller, which generates no axial force.

02.The volute casing adopts a double - volute structure to balance radial forces. The transition flow passage adopts a structure with two symmetrically - arranged components spaced 180 degrees apart. This overcomes hydraulic imbalance caused by wear. By applying the design concept of space guide vanes, it minimizes impact wear within the flow passage, preventing vortex - induced wear. It conforms to the flow of water, with no sharp bends, resulting in very low bend - related wear.

03.The new - type seal ring is equipped with two O - ring seals and radial protrusions in the radial direction. The two O - ring seals enhance the sealing performance between the seal ring and the pump body. The outer protrusions on the seal ring can cover part of the gap between the pump body and the seal ring, preventing the conveyed medium (sandy water) from eroding the pump body by impact, thus extending the service life of both the pump body and the seal ring. The design of this seal ring has been granted a "Utility Model Patent Certificate" by the National Intellectual Property Administration.
04.Large - sized pumps adopt a structural form that combines sliding bearings and rolling bearings. Sliding bearings operate stably, reliably, and with low noise. Under liquid lubrication conditions, the sliding surfaces are separated by lubricating oil and do not come into direct contact, reducing friction losses and surface wear, and also lowering the temperature rise of the bearings. To address the axial residual axial force, a combined bearing structure with a rolling bearing installed at the end of the sliding bearing is adopted at the non - drive end. The sliding bearing and the sliding bearing seat are in spherical surface fit, which is beneficial for aligning the bearings at both ends during the assembly of the entire pump unit and simplifies the assembly process of the entire pump unit.
