Sealless Pumps
An ordinary mechanical pump using a mechanical seal has the drawback of getting worn out due to friction or wear and tear over continual use. This leads to a safety risk as hazardous chemicals may leak into the outside environment. Sealless pumps overcome this drawback by completely enclosing the wet-end of the pump. This eliminates the need for a seal and makes sealless pumps the ideal choice for systems dealing with hazardous liquids such as toxic chemicals, acids and other volatile compounds.
Sealless pumps are centrifugal pumps that lack the dynamic mechanical shaft seal that normally seals the pump shaft. A static containment shell is used to replace the dynamic seal and provide a completely sealed liquid end or pressure boundary. Drive by Magnets Sealless pumps have a unique sealless construction that allows them to pump caustic and hazardous chemicals without fear of leakage or emissions. The Sealless Pump is made up of only three parts: the front casing, the impeller, and the rear cover. The pump’s structure is quite basic and needs little maintenance, resulting in cost savings for repair and replacement parts during its lifespan.
