With the gradual recovery of the global economy, multiple industries such as manufacturing, energy development, food processing, and water treatment have ushered in a new round of growth opportunities. Particularly in major economies such as Asia, North America, and Europe, the accelerated advancement of infrastructure construction, the continuous deepening of green energy transformation, and the rapid popularization of intelligent manufacturing technologies have all placed higher demands on industrial equipment.

Centrifugal pumps are widely used in industrial production and daily life for fluid transportation. Their normal operation is crucial for many systems. However, during long - term use, various problems inevitably occur. Therefore, the maintenance and repair of centrifugal pumps are quite important aspects.

As a representative of positive displacement pumps, screw pumps are widely used in industries such as petroleum and chemical engineering due to their compact structure, stable operation, and adaptability to complex media. They particularly excel in conveying high-viscosity fluids, particle-laden media, or shear-sensitive materials. However, in practical applications, improper selection often leads to issues such as low efficiency, increased energy consumption, and frequent failures, primarily because users focus only on basic parameters like flow rate and head while neglecting medium characteristics, operating conditions, and long-term costs. This article analyzes common selection misconceptions and provides systematic, science-based methods to help users accurately match equipment needs and enhance the overall efficiency and economy of pumping systems.

If you're after a pump that's tough, efficient, and built to last, the Open Top Type Single Screw Pump should be at the top of your list.

In high-risk industries such as chemical, pharmaceutical, and new energy, leakage from fluid transportation equipment not only causes material waste but also risks safety accidents and environmental pollution. Leak-free pumps, with their revolutionary sealing technologies, completely solve the leakage problems of traditional pumps. This article details the technical principles, application scenarios, and core differences of four major leak-free pump types—canned motor pumps, magnetic drive pumps, positive displacement diaphragm pumps, and electromagnetic pumps—providing a comprehensive selection reference for industrial fluid transportation.

Centrifugal slurry pumps are widely used in slurry transportation. Their pros and cons vs. other types (positive displacement, pneumatic diaphragm, screw pumps) lie in structure, performance and application.TEFFIKO, a veteran in pump equipment, offers advanced, quality products for efficient slurry solutions.
