Applications
Mining: what vacuum pumps are used for
For each application: what the vacuum does and which series the manufacturers name for it. The information comes from the manufacturers’ own pages.
Vacuum filtration and dewatering
The pressure difference drives the liquid through the filter and dewaters the solids. Edwards names filtering and dewatering with liquid ring pumps as tasks in mining, Busch vacuum filtration with the DOLPHIN.
Methane gas and exhaust gas recovery
Edwards names methane gas extraction with liquid ring pumps. Busch lists exhaust gas recovery with the MINK and describes the extraction and compression of flare gas with DOLPHIN and MINK.
Flotation and flocculation
Blowers introduce air into the flotation cell and stir up the flocculant. Busch names the TYR rotary lobe blowers and the SAMOS side channel blowers for this.
Priming centrifugal pumps
Vacuum fills the suction line and the water chamber so that the centrifugal pump starts. Busch names the DOLPHIN liquid ring pumps for this, for filling the water pump and for water chamber priming.
