In various application scenarios such as petrochemical industry and industrial processes, split-case centrifugal pumps have become the preferred power equipment for many key systems due to their unique design and stable performance. This article provides a practical split-case centrifugal pump selection guide to help engineers, procurement decision-makers, and EPC contractors avoid common misunderstandings and select high-performance pump models that truly match project requirements.

In industrial fluid systems, the performance of an oil pump depends not only on the pump body itself, but also on whether the motor driving it is matched. Choosing the wrong motor will, at best, lead to low efficiency and soaring energy consumption, and at worst, cause overheating, shutdown and even safety accidents. Based on engineering practice, this article systematically sorts out how to scientifically select an oil pump motor around the eight dimensions you provided — not only meeting process requirements, but also taking into account safety, energy efficiency and long-term costs.

Centrifugal pumps are the backbone of industrial fluid transfer, widely used in water treatment, oil and gas, manufacturing, chemical, and other sectors. Their stable operation relies on the seamless collaboration of internal precision components. Whether you’re selecting a pump, performing maintenance, or making a purchase, grasping the key details of these core components is absolutely essential. Below, I’ll break down the main parts of centrifugal pumps—their functions, types, and key points—based on practical on-site experience.

Centrifugal pumps are the "workhorses" in industries such as water treatment, oil and gas, and manufacturing. Outlet pressure (also known as discharge pressure) and flow rate are their most critical performance indicators. The correlation between these two directly determines the pump's efficiency, energy consumption, and system stability. Whether you are engaged in engineering design, equipment operation, or other related fields, mastering this relationship is the key to optimizing equipment performance and avoiding detours. Below, combined with practical industrial on-site experience, we analyze their interaction, influencing factors, and practical applications—all practical insights

Why do centrifugal pumps have quotes ranging from several thousand yuan to several hundred thousand yuan? It’s not that merchants are arbitrarily pricing them! I’ve organized some notes—all dry goods from actual procurement pitfalls and manufacturer inquiries. Understand this and save money on unnecessary expenses～
