Customer Challenges
Improve High-Viscosity Adhesive Feeding Stability
High-viscosity materials require controlled feeding pressure and stable flow to support consistent downstream metering and dispensing.
High-viscosity adhesives can be difficult to transfer from the original drum. Unstable feeding pressure may affect material flow, while insufficient drum utilization increases material waste and production cost.
After a drum change, air may enter the material path and affect downstream dispensing. Moisture-sensitive materials may also require controlled protection during storage and feeding.
BL-020 Progressive Cavity Drum Pumps with Follower Plate provide low-pressure feeding with PID pressure regulation and automatic flow adjustment. Optional vacuum degassing can remove air after drum replacement, while an optional vacuum device can help protect moisture-sensitive materials.
Product Overview
Controlled Drum Feeding for High-Viscosity Materials
Progressive Cavity Drum Pumps with Follower Plate supply material from the original drum to downstream metering, mixing or dispensing equipment. They are designed for high-viscosity industrial adhesives and potting compounds.
The BL-020 combines a follower plate, servo progressive cavity feeding unit, pressure-control system, automatic flow adjustment and material-level monitoring in one integrated machine.
Optional functions include vacuum degassing after drum replacement, vacuum protection for moisture-sensitive materials and drum barcode scanning.
Efficient Drum Changeover
The ergonomic drum-change structure helps operators replace material drums more conveniently during production.
Material-level detection provides visibility of remaining material, helping operators plan drum replacement before material supply is interrupted.
A safety protective enclosure helps create a safer operating environment around the feeding mechanism.
Core Functions
Key Features
Wide Viscosity Range
Handles materials from 3,000 to 2,000,000 mPa·s for demanding high-viscosity adhesive feeding applications.
Low-Pressure Material Feeding
Supplies material under controlled low pressure to support stable downstream metering and dispensing conditions.
High Drum Utilization
Achieves more than 95% material utilization from the drum, helping reduce residual material and waste.
PID Pressure Regulation
Controls feeding pressure to help maintain a stable material supply during production.
Vacuum Options
Optional vacuum degassing removes air after drum replacement, while optional vacuum protection supports moisture-sensitive materials.
Production Monitoring
Level detection, automatic flow adjustment and optional drum barcode scanning support controlled material management.
Working Process
How It Works
The follower plate presses into the material drum while the progressive cavity pump transfers high-viscosity material to the next process under controlled pressure.

Frequently Asked Questions
FAQ
What viscosity range can the BL-020 handle?
The BL-020 is suitable for materials with viscosities from 3,000 to 2,000,000 mPa·s.
How much material can be used from one drum?
The system can achieve material utilization above 95% from the drum, depending on the material and operating conditions.
Can the system remove air after a drum change?
Yes. An optional vacuum degassing function can remove air from the material after drum replacement to support bubble-free dispensing.
Can the pump feed moisture-sensitive materials?
An optional vacuum device can be configured for materials that require protection from ambient moisture.
Can Progressive Cavity Drum Pumps with Follower Plate connect to dispensing systems?
Yes. The BL-020 supplies material to downstream metering, mixing and dispensing equipment. The final connection should match the selected material and process layout.
