It consists of rotators, cross diffuser, separator shaft, induction wheel, pressure increased impeller, directive wheel,top and lower connection. Function: 

It's the suction port for well fluid entering the submersible centrifugal pump. Meanwhile, free gas can be separated prior to flowing into the submersible centrifugal pump, therefore relief gas effect on the pump unit.. Characteristics: 

1. It can separate 90% free gas from the mixture while GAL reach to35%. 

2.It adopts netted sealing structure at the port for the protection of the pump unit. 

3.High strength sand-resistant sleeve can effectively avoid casing fracture and pump lost in well under high sand content conditions. 

4.Tandem separators can be provided to improve the gas and oil separation.
