Vacuum filtration of mineral slurries requires the rugged design of Vooner’s vacuum pumps, which includes cone ports and the liquidring eccentric corner in a solid housing. Vooner offers different materials of construction using various amounts of stainless steel for erosion and corrosion protection.
Long-lasting 316 stainless steel is used for fly ashconveying systems and condenser vacuum for geothermal power plants. Cast iron two-stage high vacuum pumps are used to exhaust condensers on steam turbines.
Vooner vacuum pumps are also used in dry corn milling applications, phosphoric acid production, anaerobic digester recirculating corrosive methane pentane gases, and CO2 gas compressors. Vooner bronze or stainless steel vacuum pumps and compressors are ideally suited to handle applications where explosive or corrosive gases are present.
