Yongjia Liangbang pipeline pump selection is based on the international ISO 2858 standard and incorporates the latest hydraulic models. It is also designed as an alternative to the SG pipeline pump, following relevant international standards. This method ensures high performance and reliability for a wide range of applications.

One example is the SGR vertical hot water pipeline pump, ideal for transporting fluid media, high-pressure boosting, water supply, air conditioning, heating cycles, fire protection, and more. It operates efficiently at temperatures below 150°C.
When selecting a pipeline pump, five key factors should be considered: flow rate, system head, liquid properties, piping layout, and operating conditions.
1. **Flow Rate**: A critical parameter affecting the system's production capacity and conveying ability. Designers typically calculate normal, minimum, and maximum flow rates. When selecting, the maximum flow rate is used, or the normal flow rate if no maximum is available.
2. **Head Requirement**: The system's head is another crucial factor. It’s recommended to increase it by 5%-10% to ensure smooth operation.
3. **Liquid Properties**: Includes the type of fluid, its physical and chemical characteristics such as temperature, density, viscosity, solid content, gas content, and corrosiveness. These determine the pump's suitability and material choice.
4. **Piping Layout**: Factors like suction height, distance, direction, and pipe specifications are vital for calculating system resistance and checking NPSH (Net Positive Suction Head).
5. **Operating Conditions**: Covers temperature, pressure, ambient environment, and whether the pump will operate continuously or intermittently.
The single-stage pipeline pump is widely used in industrial and urban water supply, high-rise buildings, fire boosting, long-distance water supply, and heating/cooling systems. Known for stable performance, reliability, and low noise, it is an excellent choice for single-suction centrifugal pumping.
The FG-type pipeline pump follows the ISO 2858 standard, using advanced hydraulic models and serving as a replacement for the SG model. It aligns with IS-type centrifugal pump standards, ensuring comparable performance and meeting all design requirements.
Similarly, the DFRG centrifugal pump is developed based on ISO 2858, incorporating the latest hydraulic technology and designed to replace the SG series. Its performance parameters match those of the IS-type pump, making it a reliable option.
