Sanitary Stainless Steel Rotary Lobe Pump for High Viscosity Peanut Butter Transfer
Bonve Sanitary Rotary Lobe Pump – The Ultimate Solution for Processing High-Viscosity Peanut Butter
Peanut butter—a nutrient-dense, high-protein spread—presents significant processing challenges due to its non-Newtonian behavior and extreme viscosity (often ranging from 50,000 to over 150,000 cP). Handling this poor-fluidity, high-fat medium requires a specialized positive displacement pump that delivers low-shear, stable flow. Our SS316L stainless steel lobe pump is engineered to manage the high pressure and internal friction of peanut butter, ensuring smooth transfer without oil separation, while maintaining the product’s creamy texture and nutritional integrity.
Overcoming Critical Pumping Challenges in High-Viscosity Peanut Butter Processing
1. Handling Extreme Viscosity & Flow Resistance
Whole strawberries, peach slices, or citrus pulp must remain intact during transfer. Mechanical crushing or over-shearing destroys the visible fruit texture, reducing product quality and consumer appeal. A gentle pumping action is not optional – it is essential.Peanut butter acts as a non-Newtonian fluid with viscosity reaching up to 150,000 cP. Standard pumps often suffer from cavitation and slippage due to heavy flow resistance, causing severe operational downtime. A high-pressure positive displacement lobe pump is essential to ensure stable, continuous transfer.
2. Preserving Texture & Preventing Oil Separation
Peanut butter is highly shear-sensitive. High-speed impellers can damage the emulsified matrix, leading to unappealing oil separation (syneresis). Our low-shear rotary lobe technology preserves the creamy texture and maintains product integrity throughout the production line.
3. Managing Abrasive Particles in Crunchy Blends
For "crunchy" varieties, abrasive nut chunks can easily jam and wear out traditional gear pumps. Our pumps are designed with wide internal clearances and hardened SS316L components to handle solids and particulates without clogging or damaging the product.
4. Meeting Strict Sanitary & CIP/SIP Standards
Thick, oily residues in peanut butter are prone to bacterial growth in "dead spots." To meet FDA and 3A hygiene requirements, the pump must support automated CIP (Clean-In-Place) and SIP (Steam-In-Place) protocols, ensuring a 100% sterile environment without manual teardown.
Why Choose Bonve Rotary Lobe Pumps for Peanut Butter Transfer?
Bonve delivers high-performance, product-friendly pumping solutions tailored to the unique rheology of nut spreads:
1. Heavy-Duty Positive Displacement for Ultra-High Viscosity
As a robust high viscosity pump, Bonve rotary lobe pumps feature a low-speed, high-torque positive displacement design with micro-clearance rotors. Even when transferring ultra-viscous smooth peanut butter (up to 150,000 cP+), Bonve acts as an efficient food grade pump, delivering stable, pulse-free discharge pressure without internal slippage.
2. Gentle Low-Shear Transfer to Prevent Oil Separation
Peanut butter requires delicate handling to maintain its emulsified state. Utilizing specialized rotor profiles, Bonve lobe pumps gently propel the medium with minimal shear stress and frictional heat. This makes it the ideal peanut butter pump to preserve homogeneous texture, prevent oil separation (syneresis), and safeguard natural flavor.
3. Gentle Handling of Crunchy Nut Particles
The spacious internal cavity allows this specialized rotor pump to pass chunky nut particulates smoothly. Nut pieces remain whole without being crushed or ground, protecting both product consistency for "crunchy" blends and the pump’s internal surfaces from abrasive wear.
4. SS316L Hygienic Design & Ultimate Safety Compliance
All wetted parts in Bonve stainless steel lobe pumps are crafted from mirror-polished SS316L with FDA-compliant mechanical seals. As a trusted hygienic pump manufacturer, our design eliminates dead spots and fully supports automated CIP (Clean-In-Place) and SIP processes, guaranteeing the strictest food safety standards for global processors.

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 Peanut butter 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.
