Description
The pump is located on the surface with the injector immersed into the well. The delivery of the fluid generated by the impeller is conveyed to the outlet, the delivery is sucked, by means of a piping through the ‘venturi system’ connected to the suction chamber, which gives the necessary depression to the suction of the fluid where the injector is immersed in.
The fluid sucked by the injector gets mixed in the venturi diffuser with the recycling fluid, coming from the injector body, consequently the fluid pressure increases and it is sucked by the pump through a piping.
Application
Note: A foot-valve must be fitted to the injector also with the valve mounted to the outlet of the pump to ensure a suitable counter pressure during operation. The pipe connecting to the injector and the pumps body must always be fitted up before starting.
