These Pumps are single stage, double suction with double delivery ports centrifugal displacement type. The Rotor revolving eccentric to casing throws the liquid by centrifugal force on casing to form a liquid ring. This ring rotates at the same speed as the rotor, seals the buckets, forces the liquid to enter and recede the individual pockets, thus creating vacuum.
For priming of large size centrifugal pumps, excavation of air from pump casing and suction pipes, siphons and turbine chambers. Drying, evaporation, Distillation, Filtration, Sterilisation, Evacuation of air from suction pipes and chambers, Priming of large pumps, Twist drilling machine, Bottle filling etc.
