Sanitary SS316 Rotary Lobe Pump For Flour Dough Transfer
In food processing operations requiring viscous dough handling, gentle shear control, hygienic design, and material integrity preservation are critical priorities.
Bonve’s 316L Stainless Steel Rotary Lobe Pump is precision-engineered to address the unique challenges of elastic flour dough transportation.
Unique Structural Advantages
The hygienic, low-shear Bi-wing rotor design utilizes food-grade 316L stainless steel, the surface roughness is controlled below 0.8 micron. to prevent dough adhesion.
Problem-Solving Capabilities
Traditional pumps struggle with dough’s demanding characteristics:
Gluten structure damage from excessive shear
Material buildup in flow channels
Bacterial risks from incomplete cleaning
Seal failures causing contamination
Bonve's engineered solutions deliver unmatched performance:
1. Hygienic sealing system:
Packaged type mechanical seals with food-grade PTFE/FKM faces and Silicon carbide/tungsten carbide, certified for direct contact
Packaged type mechanical seal replace all components in ≤15 minutes, reducing downtime by 65%.
2. Shear-sensitive operation:
Bi-wing rotors with 0-80 RPM speed range maintain dough elasticity.
Rectangular feed port flow channels prevent compression damage to dough structure.
3. Sanitation optimization:
Full CIP/SIP compatibility with <0.8 surface roughness (Ra) for zero residue retention.
Quick-disassembly design: Entire rotor chamber opens in 3 steps without tools.
Industry-Specific Performance Enhancements
Tailored for bakery and pasta production lines:
Pump jacket: With the pump's built-in thermal jacket, the temperature can be freely controlled to keep the dough at 10-25°C to prevent premature fermentation.
Versatile handling: Transfers dough with inclusions (grains, nuts ≤5mm) without crushing.
Mechanical Seal Innovation
The quick-release sanitary sealing system combines:
Rapid-disassembly design: Tool-free cartridge seals enable full seal replacement in ≤8 minutes, cutting cleaning downtime by 50%.
Wear-resistant materials:
Primary seal: Silicon carbide (SiC)/tungsten carbide (TC) rotating faces eliminate abrasive particle generation.
Secondary seal: FDA-compliant FKM fluorocarbon rubber or PTFE spring-energized seals.
Cross-Industry Adaptability
Proven effective in food applications:
Bread dough lines: Handles 70% hydration doughs at 12 m³/h with 92% structural integrity retention.
Pasta extruders: 30% lower energy consumption vs. screw conveyors.
This advanced design achieves 98% production uptime in 24/7 bakeries, with 60% lower maintenance costs compared to conventional dough pumps.
About Bonve Rotary Lobe Pump
Bonve Rotary Lobe Pumps is a specialized positive - displacement pump with its non-contact pump element design has the ability to cover a wide range of applications in industry. The hygienic design, anti-corrosive stainless steel construction and smooth pumping action have long established these pumps in the food, beverage, dairy and pharmaceutical industries.
Features include:
• Gentle transfer of delicate suspended solids.
• Bi-directional operation.
• Compact size with high performance and low energy input.
• Ability to pump shear sensitive media.
• Easy maintenance.
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.

Main Parts of the Complete Pump
Bonve complete pumps are usually composed of bare shaft pump, coupling and its guard, geared motor and base plate. With your order, bare shaft pump or complete pump is supplied.
Bare Shaft Pump Structure
Structure Details
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 characteristic 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.
