Stainless Steel Food Grade Rotary Lobe Pump for Ketchup
Ketchup, as a typical non-Newtonian fluid, places extremely high demands on conveying equipment during production, processing, concentration, storage, filling, and transportation. Its physical properties—such as high viscosity, high particulate solids content, and shear sensitivity—often pose significant challenges to conventional conveying methods.
Challenges in Tomato Sauce Transportation Industry
1. Extremely High Viscosity
Tomato concentrate typically has very high viscosity, causing conventional centrifugal pumps to experience a sharp drop in efficiency under such conditions—sometimes failing to draw in or transport the fluid, resulting in pipeline blockages and production halts.
2.Solid Content and Particle Integrity Protection
Tomato sauce often contains tomato seeds, fibers, or diced pieces (such as chopped tomatoes). If the internal clearance of the pump is too small or the flow rate is too high, particles may be crushed or compressed, compromising the product's texture and sensory characteristics.
3.Shear Sensitivity
Ketchup is highly sensitive to shear forces. High-speed pumps can disrupt its fiber structure and consistency, leading to "weeping" or thinning of the texture, which affects the final product's grading.
4.Stringent Sanitation and Cleaning Requirements
As a food-grade medium, ketchup transportation must comply with FDA or 3A sanitary standards. The sauce is prone to accumulation and fermentation in dead corners; traditional mechanical seals or pump chamber designs that fail to enable CIP and SIP may result in microbial contamination exceeding limits.
5.Equipment Wear and Seal Failure
Tomato sauce is slightly acidic and contains particulates that can cause abrasive wear on pump components during high-speed flow. Conventional seal designs are prone to damage from high pressure or particle ingress, resulting in costly downtime and maintenance.
Bonve, as a "delivery expert" in the tomato sauce industry
Bonve ofters the broadest range of its Rotary Lobe Pumps for ketchup Industry. As an excellent pump manutacturer, our hard technical barriers have become a powerful help for our Bonve pumps reform and innovation. So far, Bonve pumps have developed to the fourth generation and are mature.

2.Targeted seal for specific application, ensure zero leakage.
Easy maintenance
1.Compact structure, easy assembling and disassembling.
2.Maintenance in place, easy cleaning. CIP able and SIP able.
3.Few wearing parts, low maintenance.
Long life
1.All main parts proceed by CNC, high precision fabrication.
2.No contact between the rotors, rotors and pump chamber.
3.six bearings with separate arrangement, high balance.
4.Adjustable seal ring extends the shaft life.
5.Axis key synchronous adjustment, no rotor collision problem.
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 chocolate 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.
