NASH Liquid Ring Vacuum Pump

Technical description

Liquid ring vacuum pumps handle gases that carry condensate, dust or solvent vapour, because the liquid ring absorbs the contaminants instead of trapping them inside the pump. NASH liquid ring machines are the standard choice for chemical, petrochemical and environmental duty.

The pump can be supplied as a bare shaft unit, on a baseplate with motor, or as a complete skid with separator, heat exchanger and seal liquid circuit. Materials of construction are selected to suit the process gas.

Typical applications

• Chemical and petrochemical vacuum duty
• Waste gas extraction and recovery
• Material conveying with wet or dusty gases
• Vacuum filtration and drying
• Environmental and effluent plant duty

Selection and configuration

Performance data depends on the duty point, the conveyed medium, the ambient conditions and the motor configuration. Send us the required flow rate, pressure or vacuum level and the installation environment, and we will confirm the exact model, impeller trim and motor for your application.
