Liquid Ring Vacuum Pump with Diverse Material Options

ELL Series Robust Water Ring Vacuum Pump with Diverse Material Options 

• Nearly isothermal compression
• Oil-free, as no lubrication in the working chamber therefore non-polluting
• Compatible with virtually all types of gases and vapors
• Able to handle small volumes of entrained liquids
• Features simplified maintenance and stable, dependable operation
• Operates with low noise levels and minimal vibration
• Offers a broad selection of construction materials, ensuring suitability for nearly all application scenarios
• Shaft design prevents direct contact with the pumped medium
• Equipped with standard cavitation protection
• Integrates a built-in dirt drain port
• Rotating components achieve zero metallic contact during operation

Note

• Ensure continuous supply of service liquid (usually water) to maintain the liquid ring and remove heat; separated liquid can be reused.
• A dirt drain allows continuous removal of contaminated liquid if needed.
• Pump rotates clockwise when viewed from the motor side.

Applications

Designed for handling both dry and moisture-laden gases, the pump can also operate reliably when small amounts of liquid are present. It is suitable for processes requiring vacuum or pressure levels within the range of 33 to 900 mbar.
