Let's talk about the differences between OH3 and OH4 centrifugal pumps. Both are horizontal centrifugal pumps, but they have different design focuses and are used in different applications.

In the field of industrial fluid transportation, the selection of centrifugal pumps directly affects system efficiency and operational stability. OH1 and OH2, as common structural types of centrifugal pumps, although both belonging to the category of horizontal single-stage centrifugal pumps, have significant differences in design concepts and practical applications. The following is an analysis from four dimensions: structural design, performance parameters, applicable scenarios, and maintenance costs.

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.

Having worked in equipment management for ten years in a chemical plant, I've handled at least dozens of pump types. The most reliable pump for handling viscous materials is undoubtedly TEFFIKO's General Type Single Screw Pumps. Since switching to this system last year, I haven't had to work overtime due to pump blockages.

This article explains the feasibility, application scenarios, key points and precautions of vertical installation of centrifugal pumps. Vertical installation is technically feasible, suitable for space-constrained environments and deep liquid extraction. It requires attention to fixed support, pipeline connection, lubrication system and maintenance accessibility. Centrifugal pumps produced by professional enterprises can meet vertical installation needs, providing efficient solutions for industrial scenarios.
