3RP Rotary Lobe Pump

3RP Rotary Lobe Pump

The 3RP Rotary Lobe Pump is a high-performance positive displacement pump designed for the hygienic and efficient transfer of high-viscosity, low-viscosity, and particle-containing liquids. Featuring advanced rotary lobe technology, the pump provides smooth, low-shear, and non-pulsating fluid transportation, making it widely used in food processing, beverage production, dairy, pharmaceutical, chemical, cosmetics, and biotechnology industries.

The pump adopts synchronized rotary lobes that rotate without direct contact inside the pump casing, ensuring gentle handling of sensitive media while maintaining high efficiency and stable flow. Its sanitary structure and easy-clean design meet strict hygiene requirements and are suitable for CIP (Clean-In-Place) and SIP (Sterilization-In-Place) systems.

Product Features

Gentle and Low-Shear Fluid Handling
The rotary lobe structure minimizes product damage and preserves the original characteristics of sensitive or shear-sensitive media.

Wide Range of Media Compatibility
Suitable for transporting liquids with different viscosities, including materials containing soft particles, fibers, or suspended solids.

Sanitary and Hygienic Design
Manufactured with smooth internal surfaces and sanitary-grade stainless steel materials, fully meeting hygienic processing standards.

Stable and Pulse-Free Flow
The synchronized rotor design ensures continuous and smooth liquid transportation with low pulsation and stable pressure output.

Bidirectional Operation
The pump can operate in both forward and reverse directions, allowing flexible installation and system design.

Easy Cleaning and Maintenance
The simple internal structure allows convenient disassembly, cleaning, and maintenance, reducing downtime and maintenance costs.

Excellent Self-Priming Capability
The pump offers strong suction performance and reliable self-priming ability for various industrial applications.

Working Principle

The 3RP Rotary Lobe Pump operates through two synchronized rotors rotating in opposite directions inside the pump chamber. As the lobes rotate, sealed cavities are formed between the rotors and pump casing, continuously transferring the liquid from the inlet to the outlet. Since the rotors do not directly contact each other, wear is minimized and sensitive media can be transported gently and efficiently.

Main Applications

The 3RP Rotary Lobe Pump is widely used in:

• Dairy product processing

• Food and beverage production

• Fruit jam and syrup transportation

• Chocolate and honey transfer

• Pharmaceutical liquid conveying

• Cosmetic and personal care product processing

• Chemical and fine chemical industries

• Biotechnology and fermentation systems

• Wastewater sludge and viscous media transfer

Suitable Media

The pump is suitable for transporting:

• Milk and dairy products

• Yogurt and cream

• Syrup and honey

• Chocolate and paste materials

• Cosmetic creams and lotions

• Pharmaceutical liquids

• Fruit pulp and jam

• Chemical liquids
