Chemical Grade SS316 Rotary Lobe Pump For Epoxy Resin Transfer

Bonve rotary lobe pump, precision machined 316 stainless steel, FFKM O-ring, good at transmitting high viscosity epoxy resin, no shear. Its synchronous two-lobe design maintains a stable flow rate even when filled with high viscosity resins or solid containing additives. The contactless rotor geometry prevents clogging of semi-cured resin particles and ensures that the pump runs without wear. These pumps have a robust mechanical seal with a temperature rating of 80°C+ resin and chemical resistant elastomers compatible with amine hardeners. With CIP/SIP functionality, the pumps help plants reduce material waste and maintenance downtime.

Bonve Lobe Pump: The Ideal Choice for Epoxy Resin Transfer
In the realm of epoxy resin handling, precision and chemical stability are of utmost importance. Bonve's state-of-the-art Stainless Steel Lobe Pump is specifically engineered to meet the unique demands of epoxy resin transfer.     

Unique Structural Advantages
The cam rotor design enables low-pulsation, high-viscosity pumping action. The precisely machined rotors work in harmony to maintain consistent flow rates while handling abrasive fillers and hardeners.     
This ensures precise mixing ratios of resin components and prevents premature curing, preserving the material's chemical integrity and bonding performance.

Problem-Solving Capabilities
Traditional pumps often struggle with air entrapment, uneven mixing, or component separation due to epoxy's dual-component nature and thixotropic properties. 
Bonve's cam rotor pump addresses these challenges with:
1.   Wear-resistant parts: SS316 parts are used to ensure no wear and no pollution during material transmission.
2.   Heating system (optional) : The heat pump body can be added to keep the material at a certain temperature and reduce solidification.
3.   Low speed: pump at low speed to ensure no cavitation, so that the material smooth transmission.
This combination reduces pump wear by 35 percent compared to other pumps, while extending seal and pump life by 50 percent in aggressive environments.

Cross-Industry Versatility
Whether in composite manufacturing (Composite glue), electronics (silicone thermal grease), or automotive (adhesive dispensing), our pump ensures:
- Zero cross-contamination (chemically inert surfaces)
- Flow rates from 0.5 to 400m3/Hr
- Viscosity handling up to 3,000,000 cP

The pump's leak-free design and rapid cleaning capabilities make it ideal for frequent material changes in multi-product facilities.


About Bonve Stainless Steel Lobe Pump

Bonve Lobe Pump 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.

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.
