Overview

A liquid-ring vacuum pump family concept for industrial vacuum service; the operating liquid forms the sealing and compression medium.

Features

• Liquid-ring compression with an eccentric impeller.
• Suitable in principle for wet gas, vapour and liquid-carryover duties after application review.
• Configuration depends on the sealing-liquid circuit and process compatibility.

Applications

• Evaporation, filtration, drying and deaeration.
• Food, paper, plastics, mining and chemical-process duties where suitable.
• Central or packaged vacuum service after duty and compatibility review.

Working Principle

An eccentrically mounted impeller rotates an operating liquid against the casing to form a liquid ring. Gas enters expanding cells, is compressed as cell volume changes, and is discharged.
