Overview of Resin Applications in Industry
Synthetic resins are indispensable raw materials in the chemical industry, widely used in:
- Composite material molding
- Electronic encapsulation and insulation processes
- Coating and surface protection systems
- Adhesive and sealing applications
As a critical class of functional and structural materials, resins play a vital role in modern industrial manufacturing.
However, handling and transfer liquid resins efficiently remains a common challenge in production environments.
The Challenge: Transferring High-Viscosity Resin
In most factories, liquid resin is typically stored and delivered in IBC containers at ambient temperature. One of the most frequent operational requirements is:
- Transfer resin from IBC containers to mixing tanks
- Feeding resin from storage tanks into production lines
At room temperature, resin viscosity usually ranges between 10,000 and 50,000cP, making it extremely difficult for conventional pumps (such as centrifugal pumps) to handle effectively. Common issues include:
- Insufficient flow rate
- Pump cavitation or blockage
- Excessive wear and frequent maintenance
- Inconsistent and unstable transfer
The Solution: Bonve Rotary Lobe Pump
With over 20 years of application experience in the resin industry, Bonve rotary lobe pumps are specifically engineered for high-viscosity fluid handling.
Key Advantages:
- Excellent performance with high-viscosity media (up to 100,000+ cP)
- Stable and pulsation-free flow, ideal for precise dosing
- Self-priming capability, suitable for IBC unloading
- Robust, self-developed mechanical seals ensuring long service life
- Low maintenance and easy servicing
- Low failure rate, ensuring continuous production
Typical Application Case
IBC to Mixing Tank Transfer
This case demonstrates a standard resin transfer process using a Bonve rotary lobe pump:
- Medium:Resin
- Viscosity:25,000 cP
- Temperature:Ambient
- Flow rate:3 m³/h
- Discharge pressure:3 bar
- Pump model:50BV12-5
- Material: SS304
- Seal type: Single mechanical seal
- Speed:280rpm
- Motor power:2.2kW
- Motor type: Ex-proof motor
System Design and Process Integration
This case represents a highly efficient and practical system design. The mixing tank is installed directly above the rotary lobe pump, creating a compact and space-saving layout.
At the pump inlet, a T-connection links both the bottom outlet of the IBC container and the bottom outlet of the mixing tank. At the pump discharge, another T-connection links to the top inlet of the mixing tank and the downstream production line.
By simply operating valves on these inlet and outlet connections, the system can flexibly switch between different functions:
- Transfer resin from the IBC container to the mixing tank
- Discharging fully mixed materials from the tank to the production line
Why Rotary Lobe Pumps Are Ideal for Resin Transfer
Compared with gear pumps or screw pumps, Bonve rotary lobe pumps offer:
- Gentler handling of shear-sensitive materials
- Better adaptability to viscosity changes
- Easier cleaning and maintenance
- Longer operational lifespan in demanding conditions
Improved process efficiency
Reduced downtime
Lower total cost of ownership
Conclusion
Efficient transfer of high-viscosity resin is essential for maintaining productivity and product quality in modern manufacturing. Bonve rotary lobe pumps provide a reliable, efficient, and low-maintenance solution for handling challenging resin applications.
If you are looking for a proven pump solution for resin transfer from IBC containers or storage tanks, Bonve’s rotary lobe pump is an ideal choice.
