Centrifugal pumps are widely used in industrial production for their simple structure and high efficiency, but face challenges when transporting solid-containing media or slurries. This article first analyzes the characteristics of solid media and slurries, then explains the working principle of centrifugal pumps and the wear and blockage issues of traditional structures in handling solid-containing media. It compares application scenarios of various slurry pumps, clarifies that centrifugal pumps, after upgrading with wear-resistant materials and flow channel optimization, excel in transporting medium-low concentration, small-particle slurries. It also introduces their applications in municipal and mining fields and optimization solutions, emphasizing that reasonable design enables centrifugal pumps to transport solid-containing media efficiently and reliably.

This article details the differences between Overhung Single-Stage Single-Suction Pumps (BB1) and Overhung Single-Stage Double-Suction Pumps (BB2) from four dimensions, offering professional references for centrifugal pump selection and introducing TEFFIKO’s pump solution services.

When industrial operations require high-pressure, reliable fluid transfer—whether in oil & gas, chemical processing, or power generation—Teffiko’s multi stage centrifugal pumps stand out as the benchmark of performance. Take the API 610 Type BB4 Single-Casing Ring-section Multistage Pump (Structure G) as an example: every detail is engineered to tackle extreme working conditions while delivering long-term efficiency. Let’s break down why Teffiko pumps are the first choice for industrial professionals.

In the system of fluid conveying equipment, metering pumps are key devices with special functions. Unlike ordinary water pumps that only perform the basic function of fluid conveyance, metering pumps can precisely deliver fluids according to preset flow rates and speeds. Therefore, they are also called dosing pumps or proportioning pumps in industrial production and are widely used in scenarios requiring strict control of fluid dosage.

Magnetic drive centrifugal pumps are seal-less centrifugal pumps that achieve power transmission through a magnetic coupling. Their core feature is the elimination of traditional mechanical seals, completely avoiding fluid leakage risks. They are suitable for conveying flammable, explosive, toxic, harmful, highly corrosive, or high-purity liquid media. Widely used in industries with strict leakage control requirements, such as chemical, pharmaceutical, semiconductor, environmental protection, and new energy sectors.

Multistage centrifugal pumps are a type of centrifugal pump that achieve high-pressure liquid transportation through the series operation of multiple impellers. Their core feature is "step - by - step pressurization". Each impeller (i.e., "one stage") gradually converts the kinetic energy of the liquid into pressure energy, ultimately reaching a relatively high discharge pressure. Multistage pumps are widely used in industries such as industry, municipal services, and energy. They are especially suitable for scenarios with high - head requirements, such as long - distance water conveyance, boiler feedwater, and mine drainage.
