Positive displacement pumps and centrifugal pumps are two common types of pumps. They have some differences in working principles, performance characteristics, and application scenarios. Next, I will specifically introduce what these differences are.

Vertical centrifugal pumps play a crucial role in the transportation of various liquids in the industrial field and can be found in industries such as chemical engineering, energy, and water conservancy.

In numerous industrial fields such as petrochemicals, wastewater treatment, and food processing, fluid transfer is one of the core links. Faced with complex media that are high-viscosity, particle-containing, or shear-sensitive, ordinary pump types often struggle to meet the demand for stable transfer. As an efficient positive displacement pump, the Progressive Cavity Pump (PCP for short) has become a "reliable workhorse" in industrial scenarios due to its unique structural design and excellent performance. This article will comprehensively break down the progressive cavity pump from its core definition, working principle, key components, core advantages to basic maintenance, helping you quickly grasp the core knowledge of this industrial tool.

In the field of industrial fluid transportation, centrifugal pumps are widely used for their high efficiency and stability. With over 80% of industrial pumping systems relying on centrifugal pumps, ensuring proper selection is crucial to prevent costly downtime caused by overload failures. This article analyzes the causes of overloads and provides targeted solutions based on industry practices, helping enterprises optimize their selection processes and improve equipment reliability.

If you’ve ever shopped for SS centrifugal pumps, you’ve probably noticed 304, 316L, and 2205 popping up everywhere. The real difference between them? Their alloy makeup—and that’s what makes their corrosion resistance night and day. I’ve worked with industrial pumps for years, so I’ll break this down simply: what’s in each, where they work best, and how to pick the right one without overcomplicating it. Let’s dive in.

In industries such as chemical engineering and food processing, stainless steel centrifugal pumps serve as "reliable assistants" for liquid transportation. They feature corrosion resistance and wide applicability. However, improper installation can lead to issues ranging from minor seal leaks to major pump vibration failures, affecting production and increasing costs. The following details the installation process from preparation to maintenance.
