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.

In scenarios such as industrial sewage discharge, municipal drainage, and agricultural irrigation, many purchasers frequently wonder, "Should I buy a submersible pump or a submerged pump?" Although both can operate in liquids, choosing the wrong one will not only increase maintenance costs but may even lead to safety hazards. Today, we will help you accurately match your needs.

Screw pumps have the following advantages: Can transport high-viscosity media, suitable for occasions where viscous media are transported; Due to its simple structure, it is easy to maintain;

This article focuses on API610 oil pump selection, explaining three core processes: preliminary operating parameter collation, standard compliance verification, and pump type & scheme comparison. It clarifies key points like medium properties and standard adaptation, recommends TEFFIKO's compliant products, and offers professional guidance for process industry pump selection.

TEFFIKO announces its participation in the 21st OGA Asian Oil & Gas Exhibition to be held in Kuala Lumpur from September 2 to 4, 2025, inviting professionals to explore cooperation.

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.
