It concludes these methods enhance efficiency and reduce lifecycle costs, with TEFFIKO offering professional support.

Centrifugal pumps and multistage pumps are key fluid-conveying equipment. Single-stage centrifugal pumps transport liquids via centrifugal force from a single impeller, featuring simple structure and easy maintenance, suitable for medium-low head and large-flow scenarios. Developed from centrifugal pumps, multistage pumps achieve high head through multi-stage pressurization with multiple impellers, with more complex structure and high sealing requirements, fitting high-pressure scenarios. Each has its strengths; selection depends on head, flow and working conditions to ensure efficient conveyance.

This article provides a comprehensive overview of the key precautions for using centrifugal pumps in high-temperature weather, aimed at helping operators effectively manage potential risks caused by heat. It covers pre-startup inspections of the lubrication system, sealing performance, and cooling system, as well as real-time monitoring of temperature, flow regulation, and detection of abnormal vibrations or noises during operation. It also includes post-shutdown maintenance tips such as gradual cooling, cleaning, and component inspection. Additional measures for extreme heat conditions, such as adjusting operating hours and applying insulation or shading, are also discussed. Proper operation and maintenance not only ensure stable performance and extended equipment life but also improve energy efficiency and reduce downtime in industrial and commercial pump systems.

This article focuses on single-stage centrifugal pumps, introducing their feature of containing only one set of impeller and pump casing, as well as their composition including impeller and pump body. It elaborates on their working principle of conveying liquid by centrifugal force generated from impeller rotation, and design features like simple structure and easy installation & maintenance. It also covers their application range across multiple fields, different classifications and maintenance methods, highlighting their importance in small and medium-sized fluid conveying scenarios.

Sewage pumps are vital in wastewater management, adapting to diverse scenarios with specialized designs. Their robust structure handles impurities via widened flow passages and cutting devices, while varied types like submersible and centrifugal models cater to different installation and sewage conditions. Efficient selection based on factors like solid content and head ensures seamless operation across municipal, industrial, and construction sectors, underpinning effective sewage conveyance and treatment.

In the system of fluid conveying equipment, metering pumps are key devices with special functions. Unlike ordinary water pumps that only perform the basic function of fluid conveyance, metering pumps can precisely deliver fluids according to preset flow rates and speeds. Therefore, they are also called dosing pumps or proportioning pumps in industrial production and are widely used in scenarios requiring strict control of fluid dosage.
