3RP Corrosion-Resistant Lobe Pumps
3RP rotary lobe pump is a stainless steel positive displacement pump characterized by stable flow, strong self-priming capability, and corrosion resistance, specifically designed for conveying high-viscosity, shear-sensitive liquid media such as syrups, chocolate, honey, yogurt, jams, gels, and bio-pharmaceuticals. The core advantage of this equipment lies in its internal components in contact with the medium, all crafted from premium stainless steel. This ensures the preservation of the medium's inherent properties and the equipment's corrosion resistance, thereby enhancing both medium quality and production efficiency.
Power: 0.75-22Kw
Flow Rate: 6-250 m³/h
Seal Type: Mechanical seal / Packing seal
Product Description
Summarize:

3RP rotary lobe pump is primarily designed for handling suspended liquids containing solid particles, highly corrosive media, and substances requiring sanitary compliance. It finds applications in brewing, biopharmaceuticals, food processing, beverages, daily chemicals, and environmental protection industries. This equipment employs two synchronously rotating rotors to achieve non-contact, synchronized rotation during suction and discharge. This design eliminates metal-to-metal friction and wear, significantly extending pump lifespan while ensuring low-noise operation and high efficiency throughout the transfer process.

Product Details:
3RP series rotor pump operates by utilizing two synchronously moving rotors to achieve medium suction and discharge. During startup, a pair of gearboxes precisely drives the two rotors to rotate synchronously in opposite directions within the pump housing. As the rotors rotate, they continuously generate high vacuum at the suction end, drawing the medium into the pump chamber while simultaneously creating high pressure at the discharge end to forcefully expel the medium.
Application:
1. In the petrochemical and energy sectors, it is widely used for transporting oil-based media such as crude oil, heavy oil, asphalt, tar, and lubricants, as well as various chemical raw materials including resins, polymers, paints, pigments, dyes, and acid-base-salt solutions.
2. Within the food and beverage industry, it is suitable for conveying food products like chocolate, condensed milk, yogurt, honey, jam, ketchup, minced meat, various alcoholic beverages, and syrups.
3. For daily chemical products, this pump is ideal for manufacturing gels, facial cleansers, shower gels, shampoos, toothpaste, skincare products, fragrances, and other personal care items.
4. In pharmaceutical applications, it handles various pill pastes, extracts, syrups, nutrient solutions, emulsions, and biological products.
Feature:
1. All components in contact with the material are constructed of stainless steel, meeting pharmaceutical-grade and food-grade hygiene standards. Quick inspection or replacement of parts like rotors can be performed without disassembling pipelines, significantly reducing downtime for maintenance.
2. The equipment operates at very low rotational speeds, enabling smooth and gentle material discharge without damaging its composition or molecular structure, which makes it particularly suitable for conveying shear-sensitive materials such as chocolate and jam.
3. With no contact friction between rotors, combined with heavy-duty bearings and reliable mechanical seals, it ensures stable, long-term leak-free operation.
