In the selection and application of screw pumps, TEFFIKO has always been committed to providing solutions that fit actual working conditions. Both single screw pumps and twin screw pumps can meet diverse conveying needs with their unique performances. To help customers make selections, TEFFIKO elaborates on the following aspects of core differences and application ranges:

The impeller wear ring is an annular component installed between the impeller and the pump casing in equipment such as centrifugal pumps. It can reduce liquid leakage to improve efficiency, while protecting the impeller and pump casing and extending the service life of the equipment. It is used in centrifugal pumps and mixed-flow pumps in industries such as chemical engineering, water conservancy, and electric power.

In marine engineering, ship transportation, and deep-sea exploration, selecting the right marine pump is key to efficient, safe operations. As an experienced marine pump R&D and manufacturing enterprise, TEFFIKO offers customized solutions for diverse scenarios, supporting from selection to delivery for worry-free operations.

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.

The flow paths of fluids are often precisely regulated by pumps. Whether it's transporting corrosive media in a chemical workshop or maintaining water circulation in building pipelines, pumps are always the core hubs for fluid control. Due to the diversity in working principles, structural forms, and application scenarios, pumps have formed a rich system of types. Clearly understanding these classifications and their advantages enables us to find the most suitable fluid transportation solutions under different working conditions.

In the industrial field, centrifugal pumps serve as core equipment for fluid transportation. Whether they are sealed or not represents a crucial decision - making point, which involves numerous complex factors such as operating efficiency, safety assurance, and maintenance costs.
