In industries like chemical processing, pharmaceuticals, food production, and biotechnology, many materials, including active enzymes, cell culture media, polymer emulsions, and yogurt are shear-sensitive. When these materials are subjected to excessive shear forces during transfer, it can lead not only to structural damage and separation but also to the inactivation of active components and the complete spoilage of the material. Nevertheless, thanks to its unique operating principle and internal design, the 3RP rotary pump efficiently conveys media while preserving the material’s original structure and activity, thereby delivering outstanding performance when handling shear-sensitive materials.
This equipment is a positive displacement rotary pump that operates using a pair of three-lobe rotors rotating in opposite directions in sync. During operation, the rotors maintain a precise, controllable, and minimal clearance with the pump chamber and with each other, eliminating metal-to-metal friction and thus preventing damage to the material caused by high-speed compression. The medium is smoothly conveyed from the inlet to the outlet within a sealed chamber, rather than being driven by high-speed centrifugal force or forced shear, which fundamentally reduces shear-induced damage to the material. This gentle conveying method effectively prevents issues such as polymer chain breakage, deactivation of active ingredients, and particle fragmentation, making it particularly suitable for conveying shear-sensitive media such as jam, yogurt, resins, colloids, and battery raw materials.
3RP stainless steel lobe pump is designed to significantly reduce flow pulsations, ensuring a continuous and uniform delivery process with minimal pressure fluctuations, thereby minimizing structural damage to materials caused by vibration and preventing impact on the piping system. Simultaneously, combined with the unit’s low-speed operation, shear effects are further minimized, effectively preserving the original structure and activity of the medium while ensuring efficient and stable delivery. This pump features a wide-bore design with spacious flow channels free of dead zones and contains no sharp corners or high-speed rotating impellers within the pump chamber, ensuring that it does not clog or leave residues when conveying media containing solid particles and fibers. Furthermore, it preserves the integrity of the particles in the medium, guaranteeing that the product’s appearance and texture remain unaffected.
This pump exhibits exceptional self-priming capability, allowing it to draw fluid directly from storage tanks or drums without the need for priming or additional lifting equipment. For shear-sensitive media, this minimizes recirculation and shear stress in the piping system, thereby reducing the risk of media degradation. To ensure production meets hygiene standards, all wetted parts of the equipment are constructed from sanitary-grade stainless steel, which is easy to clean and leaves no residue, complying with the clean production requirements of the food, pharmaceutical, and biotechnology industries while reducing maintenance costs and the risk of downtime. 3RP high-viscosity rotary lobe pump ensures that shear-sensitive media retain their original structural properties during transfer through its frictionless operating principle, low-pulsation flow, wide-bore design, and self-priming capability, thereby enhancing material quality.
