Bonve Sanitary Rotary Lobe Pump – The Ultimate Solution for Processing High-Viscosity Peanut ButterHot sauce production often involves heating, blending, cooking and filling. During these steps, the product viscosity can change as temperature changes. Chili, tomato or vegetable particles may also affect the flow resistance and the required pump configuration.
An unsuitable pump may create excessive shear, entrain air or deliver an unstable flow to the filling machine. High temperature can also place additional demands on the mechanical seal, elastomer and product-contact components.
A sanitary rotary lobe pump provides positive displacement transfer with adjustable speed. This allows the operator to match the pump output to the sauce condition, tank level, pipeline resistance and filling-line demand.
Main Challenges When Pumping Hot Sauce
Sauce viscosity may change significantly during heating cooling and holding.
Chili, tomato, garlic, onion or vegetable particles may require a suitable rotor and clearance configuration.
Excessive pump speed can increase aeration, foaming and unnecessary product stress.
High-temperature operation requires application-specific mechanical seal and elastomer selection.
Thick sauces and pastes may require sufficient suction conditions and properly sized inlet piping.
Unstable discharge flow can affect filling accuracy and create pressure fluctuations in the transfer line.
Rotary Lobe Pump Solution for Hot Sauce Transfer
Controlled Positive Displacement Transfer
The rotary lobe pump transfers product by moving a defined volume with each rotor revolution. With a variable-frequency drive, the pump speed can be adjusted for different sauce viscosities, temperatures, tank levels and filling rates.
Low-Shear Handling for Viscous Sauces
The non-contacting rotor design maintains clearance between the rotors and pump casing. When operated at a suitable speed, the pump provides gentle transfer and helps reduce unnecessary shear and aeration in hot sauce, ketchup, tomato paste and other viscous food products.
Application-Specific High-Temperature Configuration
For hot sauce applications, mechanical seal and elastomer materials should be selected according to the actual operating temperature, sauce composition, acidity, solids content and cleaning conditions. BONVE can review these conditions before finalizing the pump configuration.
Hygienic Product-Contact Path
The pump can be configured with stainless steel product-contact components, sanitary connections and suitable seal arrangements for food processing. CIP-compatible product-contact paths and optional SIP arrangements can be reviewed according to the process requirements.

Working Principle
Bonve lobe pumps basically consist of two lobe rotors, which rotate synchronously driven by a pair of synchronous gears in the gearbox. The rotors are driven by the main shaft and sub-shaft to rotate in a synchronous reverse direction, which changes the pump capacity, builds up high vacuum and discharge pressure, thus an efficient pumping is formed. Gap is kept between the rotors and between the pump casing, no friction, long life, no damage, no physical and chemical reaction to the pumped products.
