Sanitary Stainless Steel Honey Pump

Sanitary Stainless Steel Honey Pump

Honey, as a complex natural fluid, requires precise handling throughout extraction, concentration, storage, and packaging. Its unique physical properties—such as non-Newtonian flow behavior, extreme viscosity variations, and high sugar content—often pose significant technical hurdles for conventional pumping systems.

Challenges in Honey Transportation Industry

1. Extremely High and Variable Viscosity
Pure honey, particularly raw or high-density varieties, exhibits extremely high viscosity that fluctuates significantly with temperature. Conventional centrifugal pumps often experience a sharp drop in efficiency under these conditions, frequently failing to prime or transport the fluid. A high-performance positive displacement pump is essential to provide the necessary torque and constant flow to prevent pipeline blockages and production halts.

2. Shear Sensitivity and Aeration Risks 
Honey is highly sensitive to mechanical shear during processing. High-speed agitation can incorporate micro-bubbles into the fluid, leading to aeration that compromises the honey's transparency and premium commercial grade. Utilizing a sanitary stainless steel lobe pump with a low-speed, gentle-action rotor design is critical to ensuring pulse-free transfer that preserves the honey's natural texture, enzymes, and clarity.

3. Sugar Crystallization and Seal Failure 
The high sugar concentration in honey makes it exceptionally sticky and prone to crystallization when temperatures drop. Residual honey can solidify between mechanical seal faces, causing abrasive wear that leads to frequent leaks and contamination risks. Integrating a heating jacket pump system is the most effective solution to maintain fluidity, while a food grade rotary lobe pump with specialized seals prevents sugar buildup and ensures long-term operational reliability.

4. Strict Hygiene and Cleaning Requirements 
In the global food industry, honey processing must adhere to stringent GMP and FDA standards. Standard industrial pumps often have internal dead zones where honey can accumulate and ferment. A CIP cleanable pump made from SS316L stainless steel is mandatory to allow for thorough cleaning and sterilization without disassembling the equipment, ensuring a zero-contamination production environment.

Bonve’s Engineering Solutions for the Honey Industry

To overcome the inherent challenges of honey transportation, Bonve has developed a series of high-performance sanitary stainless steel lobe pumps that integrate advanced thermal management and gentle handling technology. Our solutions focus on ensuring production continuity, product integrity, and long-term reliability.

1. Thermal Management with Integrated Heating Jackets To solve the problem of high viscosity and "cold start" failures, Bonve pumps feature a bespoke heating jacket design. By circulating hot water or steam through the pump cover and casing, our system maintains the honey at an optimal, consistent temperature. This significantly reduces fluid resistance, prevents sugar crystallization, and ensures a smooth, high-torque startup even for the thickest Manuka honey.

2. Low-Shear, Non-Contacting Rotor Technology Bonve utilizes specialized low-speed rotary lobe pump technology to address shear sensitivity. Our rotors are precision-engineered to maintain a pulse-free flow with generous internal clearances. This non-contacting design ensures that the honey is moved gently without being "worked" or agitated, effectively preventing aeration and preserving the natural enzymes, flavor, and crystalline-free transparency of the final product.

3. Advanced Sealing Systems for High-Sugar Environments Recognizing that sticky sugar solids are the primary cause of seal failure, Bonve offers a range of high-performance mechanical seals specifically for the honey industry. Our food grade rotary lobe pump is equipped with specialized single or double mechanical seals featuring flushable designs. These seals prevent honey from solidifying on the faces, eliminating abrasive wear and ensuring a leak-free operation that protects both the machine and the product environment.

4. Zero-Dead-Zone Design for Total Hygiene (CIP/SIP) Bonve pumps are constructed from premium SS316L stainless steel with a surface finish meeting the highest global standards. Our engineering eliminates dead corners within the pump chamber where honey could stagnate. This makes the pump fully CIP (Clean-in-Place) and SIP (Sterilization-in-Place) compatible, allowing for rapid, thorough cleaning without disassembly, thereby meeting strict FDA and GMP regulatory requirements.

5. Robust Positive Displacement for High-Efficiency Output Unlike centrifugal pumps that lose efficiency as viscosity increases, Bonve’s positive displacement lobe pump provides a constant flow rate regardless of pressure changes. This ensures that your production line receives a steady supply of honey, maximizing the efficiency of downstream concentration and filling equipment while reducing overall energy consumption.

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 honey transfer applications,Bonve stainless steel lobe pumps are widely used in the food, dairy, confectionery, beverage, and wine industries.  Typical transfer media include: chocolate, condensed milk, cheese, mayonnaise, yogurt, honey, syrup, sucrose, ketchup, tomato paste, butter, concentrated juice, jam, ice cream, milk, 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.
