This pump is based on the Venturi principle, which consists of the passage of a fluid through a reduced area in which a change from potential to kinetic energy takes place at the nozzle outlet, thus causing suction of formation fluid. These fluids enter a constant area called the throat, in which the mixture of fluids undergoes a change from kinetic to potential energy at the entrance to an expanded area called the diffuser, where the potential energy is responsible for carrying the fluid up to the surface.

• For evaluations or early production, a portable surface unit is needed. A stationary unit is needed for producing wells.
• Motor fluids which can be used in this system are water, oil, diesel or others. Return fluids can be stored in on site tanks or sent to a production station which, in both instances, allows the injections, yield and gas flow to be measured.
• There are no depth or temperature limitations for this kind of artificial lift systems. The Jet Claw® pump can be installed in single or double bed completion structures.
• In order for the system to work, a high pressure unit is needed on the surface. It can be either a positive shifting or a Netzsch progressive cavity pump (PCP); a separator and a pump.
