3RP series horizontal lobe pumps deliver efficient production in chemical and food industries through low-shear transfer, zero-leakage operation, corrosion-resistant stainless steel construction, and easy maintenance. Their cross-industry application from industrial to food-grade standards establishes them as true multi-industry transfer experts.
Generally speaking, traditional centrifugal pumps experience a significant drop in efficiency when handling media with viscosities exceeding 500 cP. While screw pumps can convey high-viscosity media, they are extremely sensitive to particulate matter. This pump employs a large-chamber cam-type rotor, enabling fluid residence time within the pump chamber to be as short as 0.5 seconds. Its shear rate exceeds 50 s⁻¹, ensuring smooth flow of high-viscosity crude oil media in the chemical industry while maintaining over 98% fruit particle integrity in food industry applications like jam production. Therefore, whether in the chemical or food industry, this equipment delivers surprisingly effective conveying performance.
3RP sanitary lobe pump employs synchronous gear drive, meaning the lobes operate without contact through an external gearbox for synchronized transmission. This reduces wear and extends service life, enabling the conveyance of high-viscosity or fine-particle-containing media such as jams, toothpaste, and resins. To prevent chemical leakage or food contamination risks during transfer, this pump employs magnetic coupling or mechanical seal-free designs to achieve complete leak-free operation and enhance safety. Simultaneously, its positive displacement transfer principle minimizes shear force on materials, making it particularly suitable for conveying shear-sensitive media like yogurt, emulsions, and polymers to preserve their original properties.
It is typically constructed from 304 or 316L stainless steel, offering exceptional corrosion resistance. It withstands chemical media such as solvents and acidic/alkaline liquids while also preventing erosion from food ingredients containing salts, sugars, or mildly corrosive components. The pump body, rotor, end covers, and other components feature a high surface finish that minimizes material adhesion, thereby reducing the risk of cross-contamination to a certain extent. This design complies with hygiene standards in both the food and chemical industries.
For the chemical and food industries, cleaning and maintenance pose significant challenges. However, the 3RP hygienic lobe pump features a modular design that enables rapid disassembly and cleaning, meeting the frequent media change requirements of the food/pharmaceutical sectors while minimizing downtime. Moreover, it handles high-viscosity fluids up to one million centipoise and possesses self-priming capability over short distances, simplifying piping design and reducing production and construction costs. 3RP stainless steel lobe pump addresses challenges in the chemical and food industries regarding sanitary safety, media adaptability, and continuous production through its broad range of conveyable media, leak-free design, low-shear pumping, and ease of maintenance. It has become one of the key pieces of equipment for fluid handling in modern chemical and food processing.
