Structural characteristics
1. Compact structure and convenient disassembly and assembly
Advanced dual suction structure design ensures high flow rate and suction lift; Compared to traditional double suction pumps, the installation area of the VG pump system and associated equipment is small. The open center design of the shell is easy to disassemble and convenient for maintenance. When parts need to be replaced, there is no need to move the pump body and inlet and outlet pipelines.
2. High efficiency and energy saving
The high-efficiency hydraulic model developed using advanced three-dimensional fluid analysis technology has a higher efficiency than previous similar products, with a maximum efficiency of 94%, which is 3% to 8% higher than the traditional split pump efficiency. It has high operating efficiency over a wide flow range, and can choose motors with smaller power to reduce operating costs.
3. Environmental protection
Based on years of user experience, cooling water connection components and shaft seal leakage discharge components are used to ensure that the pump room is clean, leak free, and in compliance with environmental requirements. The pump operates with low noise and low vibration, ensuring a comfortable working environment.
4. High conveying performance
By adopting an excellent hydraulic model, the cavitation performance of the water pump is excellent, ensuring stable operation at lower water levels and improving the pumping capacity of the water pump.
5. Unique impeller structure design
Adopting an adjacent blade staggered design, the hydraulic pulse is reduced to a lower level after water enters both sides of the double suction impeller, reducing vibration and noise.
6. Structural design of large bearing body
Adopting a large bearing body structure, a unique design is made for the installation position of the pump bearing body. The large bearing body structure bearings can be lubricated with both grease and thin oil, and cooling water is supplied to the high load pump bearing body to ensure safe and stable operation of the bearings under all working conditions.
7. Reliable bearings and monitoring devices
Installing PT100 temperature measuring elements, bimetallic thermometers, and bearing vibration measuring devices can achieve monitoring of bearings in the pump room and on-site.
8. Multiple shaft seals for selection
Optional packing seals, injection type soft packing seals, mechanical seals, etc.
9. Adopting a unique packing gland design
Using a packing gland, it is very convenient to install, disassemble, and replace the packing.
10. Beautiful appearance
Adopting an external shape and optimized design through 3D Solidworks, all flange nuts on the middle opening are made of GB923 stainless steel cap nuts; Beautiful and concise appearance.
11. Optimize the design of a common base
Adopting a common base, optimizing the design to reasonably reduce the weight of the base while ensuring its strength; All bases are equipped with adjustable ears, making installation and alignment very convenient.
12. Material matching
The combination of multiple materials enables pumps to be used in a wider range of fields; The materials are matched according to the requirements of working conditions and media, and can also be adjusted appropriately according to user needs.
