water‑ring vacuum pumps(Second‑Hand)

2BEC42 Liquid Ring Vacuum Pump (Used Equipment)
The 2BEC42 single-stage liquid ring vacuum pump is a reliable substitute for imported 2BE4 series models, widely used in medium and large paper production lines. It supports long-term continuous operation and handles gas with water vapor and tiny fiber impurities.
Integrated gas-water separator, flexible multi-directional pipe connection. Two drive types available: belt drive and gearbox direct drive.
Core Advantages
1. Stable operation: Heat-treated welded impeller with high-precision dynamic balance, low vibration and fault rate, adaptable to fluctuating working loads.
2. Easy maintenance: Clearance adjustable without full disassembly; reserved inspection ports for quick scaling and corrosion check.
3. Flexible material: Standard ductile iron for regular conditions; optional stainless steel and high-alloy castings for corrosive environments.
Performance Note
Limit vacuum refers to absolute pressure. Tested at 15°C water temperature; pumping capacity changes with actual vacuum level.
Applications
Paper machine vacuum dewatering, couch roll and suction box vacuum supply, paper picking and transfer. Also applicable to pulp processing, chemical industry and other rough vacuum scenarios.
