Positive Displacement Sealless Technology.
Sealless refers to the absence of a dynamic seal where the pump shaft penetrates the pump casing. Sealless pumps are often magnetically driven or sealed using o-ring and bushings in reciprocating designs. Common technologies include hose pumps, air-operated diaphragm (AOD) pumps, eccentric disc pumps, or metering pumps. Common rotating sealless positive displacement pumps include vane pumps, internal and external gear pumps. Sealless pumps are used for various reasons, but mostly when pumping volatile or toxic liquids where any amount of leakage cannot be tolerated.
Anderson Process partners with trusted sealless pump manufacturers — including Almatec, Blackmer, Envirogear Pumps, Graco, Liquiflo, Flowrox, Mouvex, Neptune, Pulsafeeder, Tuthill and Wilden — to offer a large selection of positive displacement sealless pumps for nearly any industrial and sanitary process application.
