Food Grade Mayonnaise Transfer Pump
Transporting mayonnaise is a high-stakes process involving a shear-sensitive, oil-in-water emulsion. Unlike simpler fluids, mayonnaise requires a pump that can manage high viscosity while exerting minimal mechanical stress. Any excessive friction or heat during transfer can trigger irreversible oil separation, destroying the product's texture and shelf-life.
Mayonnaise is a complex Oil-in-Water (O/W) emulsion that requires specific handling due to its unique physical and chemical properties:
- High Viscosity & Thixotropy: Mayonnaise is a thick, semi-solid paste. It is thixotropic, meaning it becomes less viscous under stress but must regain its "stiff peak" and body once in the final container.
- Shear Sensitivity: The suspension of oil droplets within the aqueous phase is delicate. Excessive mechanical force can destabilize the molecular bond, leading to product failure.
- Biological Sensitivity: Containing eggs and proteins, it is a highly sensitive medium that requires a sterile environment to prevent spoilage and extend shelf-life.
-
Non-Newtonian Behavior: It does not flow like water; it requires positive displacement to move through pipelines without losing its structural integrity.
Transportation Challenges & Industry Pain Points
The mayonnaise industry faces several critical "pain points" during the transfer process that can impact profitability and brand reputation:
- Emulsion Breaking (Oil Separation): The biggest risk is "breaking" the emulsion. Inefficient pumping triggers syneresis, causing the oil to separate from the solids, resulting in a thin, unmarketable liquid.
- Texture Degradation: High-speed pumps often exert too much shear, which permanently thins the mayonnaise, causing it to lose the rich mouthfeel that consumers expect.
- Microbial Contamination: Because of the egg content, any "dead zones" or gaps inside the pump can harbor bacteria. Incomplete sterilization during CIP cycles is a major risk for food safety.
- Air Incorporation & Oxidation: Standard pumps can introduce air into the paste, leading to foam generation. This causes filling inaccuracies and accelerates lipid oxidation, which turns the sauce rancid.
-
Pressure vs. Speed Conflict: Moving thick mayonnaise through heat exchangers or long pipes requires high pressure, but traditional pumps often increase speed to achieve this, which destroys the product.
BONVE’s Targeted Solutions
Bonve has developed a specialized line of Sanitary Rotary Lobe Pumps designed to neutralize these specific industry challenges:
- Gentle, Low-Shear Transfer: Our optimized rotor geometry provides large internal cavities, allowing the mayonnaise to pass through at low speeds. This preserves the emulsion stability and ensures the final product maintains its thick, creamy texture.
- Superior CIP/SIP Construction: The pump is built with SS316L stainless steel and features a gap-free, dead-zone-free interior with mirror-polished surfaces (Ra < 0.8μm). This ensures 100% effective Clean-in-Place and Sterilize-in-Place cycles, eliminating microbial risks.
- Vacuum-Tight Sealing: We utilize high-performance mechanical seals specifically designed for sticky food pastes. This prevents air entrainment and oxidation, protecting the flavor and ensuring consistent filling weights.
- High Volumetric Efficiency: Bonve pumps provide powerful positive displacement, capable of handling high discharge pressures at low RPMs. This moves the thickest mayonnaise effortlessly without generating heat or shear.
- Factory-Direct Reliability: By working directly with Bonve, you receive customized engineering support and a pump built for long-term durability with minimal maintenance costs.

Bonve has an advantage over lobe pump that no other company can match.
1.Rotor:The error of the rotors processed by CNC is extremely small. The unique rotor perfectly seals the inlet and outlet of the pump. The vacuum degree of the pump is up to -0.095MPA. The rotor material and type can be selected according to the characteristics of the pumped product.
2.Shaft: The transmission shaft is processed by CNC machining center, which has characteristics of high precision, high bending strength and strong wear resistance.
3.Pump cavity: The pump cavity is sealed by a pump cover that can be opened quickly, enabling quick maintenance of the pump. The pump body is processed by CNC machining.
4.Gears:High-precision, High-Standard synchronous gears have good meshing, smooth transmission, low noise, and excellent bearing capacity.
5.Mechanical seal:The seal material and type are selected according to the characteristices of the pumped product, to ensure zero leakage, no pollution, and more environmental production.
6.Bearings: Six bearings arranged in a separate arrangement increase the concentricity of the pump operation, enhance the bearing capacity of the shaft and make the pump running more stable, thereby increasing the service life of the shaft and the mechanical seal.
7.Gear box: The gear box is processed by CNC, with high precision, high concentricity and strong versatility.
8.Spindle:We use splines the bearings and spindle, makes the pump less likely to slip. The high-precision spline makes the pump run more smoothly, and the service life is much higher than that of its peers.
More applications
In addition to mayonnaise transfer applications,Bonve stainless steel lobe pumps are widely used in the food, dairy, confectionery, beverage, and wine industries. Typical transfer media include: condensed milk, cheese, mayonnaise, yogurt, honey, syrup, sucrose, ketchup, tomato paste, butter, concentrated juice, jam, ice cream, yeast slurry, meat paste, jelly, condiments, soy protein, various beverages, and wine.
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.
