Unlike traditional fixed transfer pumps, the mobile rotary lobe pump can be easily moved to different production lines or working areas, offering operational convenience and flexibility. It is widely used in industries such as food and beverage, dairy, pharmaceuticals, cosmetics, chemicals, and wastewater treatment, where high hygiene standards and stable flow performance are essential.
With rotary lobes rotating synchronously inside the pump housing, the device achieves gentle, pulsation-free liquid transfer while maintaining product integrity. Whether the liquid is high-viscosity syrup, oil, slurry, or chemical fluid, the mobile rotary lobe pump system ensures efficient and continuous operation.
The pump is installed on a mobile cart or stainless steel trolley equipped with lockable casters, making it easy to transport between workstations or production lines. This plug-and-play system can be quickly connected to pipelines or hoses without requiring complex installation.
As a positive displacement rotary lobe pump, it provides a constant flow rate regardless of pressure variations. This ensures stable operation even when handling viscous or shear-sensitive materials, outperforming centrifugal or vane pumps in such conditions.
For industries such as food, dairy, and pharmaceuticals, the pump head and wetted parts are made of 316L stainless steel, polished to sanitary-grade standards. The design complies with CIP (Clean-In-Place) and SIP (Steam-In-Place) procedures for easy cleaning and maintenance.
The rotary lobes create large cavities that gently move the liquid through the pump without damaging its structure. This makes it ideal for shear-sensitive fluids such as creams, gels, fruit pulp, yogurt, cosmetics, and biopharmaceutical ingredients.
The pump operates with high volumetric efficiency, low pulsation, and minimal vibration. The precision-machined lobes and optimized sealing structure ensure low operating noise and smooth performance, even under continuous operation.
The mobile unit allows bidirectional operation, enabling liquid transfer in both directions simply by reversing the motor rotation. This makes the system suitable for filling, unloading, circulation, and tank transfer applications.
The pump’s modular structure allows easy disassembly and inspection. The front-loaded design enables quick access to the lobes and seals, minimizing downtime for cleaning or replacement.
The rotary lobe pump operates based on the positive displacement principle. Two synchronized lobes rotate within the pump housing without touching each other. As the lobes rotate:
The space between the lobe and casing increases, creating a vacuum at the inlet.
Liquid is drawn into the cavities and trapped between the lobes and housing wall.
The rotation carries the trapped liquid toward the discharge side.
The volume decreases, and the liquid is pushed out at a steady flow rate.
Since there is no internal contact between the lobes or housing, wear is minimized, and maintenance costs remain low. Compared to rotary vane pumps or gear pumps, rotary lobe pumps offer better sanitary performance, lower shear, and easier cleaning.
A standard mobile rotary lobe pump system consists of the following key parts:
Pump Head (Lobe Chamber): Made of stainless steel with two or three-lobe rotors that rotate in synchronization.
Mechanical Seal System: Double or single mechanical seal ensures no leakage during operation.
Drive Motor: Options include electric motors, variable frequency drives, or explosion-proof motors depending on application needs.
Coupling and Guard: A stainless-steel or aluminum coupling ensures stable power transmission and safety.
Mobile Trolley: Mounted on a heavy-duty frame with swivel casters and locking brakes for safe mobility.
Control Panel (Optional): For adjusting flow rate, speed, and monitoring motor protection.
Inlet and Outlet Ports: Typically horizontal (side-to-side) or vertical (top-to-bottom) orientation for different piping setups.
The mobile rotary lobe pump system is a versatile solution used in multiple industries for various liquid transfer tasks. Below are some of the most common applications:
Transfer of syrups, honey, molasses, chocolate, sauces, juices, and dairy products
Used in mixing, filling, unloading, or circulation processes
Maintains product quality and taste with gentle pumping
Transfer of ointments, gels, lotions, toothpaste, creams, and liquid medicine
Compliant with GMP and FDA hygiene standards
Optional sanitary design with polished internal surface
Handling acids, alkalis, solvents, lubricants, adhesives, and resins
Suitable for high-viscosity and corrosive liquids
Available with PTFE or FKM seals for chemical compatibility
Transfer of sludge, wastewater, and oily emulsions
Resistant to abrasive media
Often used in mobile dewatering and sludge treatment systems
Ideal for milk, whey, yeast, and beer transfer

Choosing the right mobile rotary lobe pump unit depends on several key factors:
Liquid Type and Viscosity – Identify whether the medium is thin, thick, corrosive, or shear-sensitive.
Flow Rate and Pressure Requirements – Determine the desired capacity and discharge head.
Temperature and Chemical Compatibility – Choose appropriate seal materials (EPDM, PTFE, FKM).
Sanitary or Industrial Use – Select food-grade or chemical-grade materials accordingly.
Mobility Needs – Decide on cart design, wheel type, and handle orientation.
Motor and Control Options – Include variable-speed drives (VFD) for adjustable flow control.
For example:
Food-grade applications → Use 316L stainless steel and sanitary tri-clamp connections.
Chemical transfer → Opt for corrosion-resistant seals and explosion-proof motors.
High-viscosity materials → Choose low-speed, high-torque models with variable frequency drives.
