1. JET PUMPS
The jet pump is a centrifugal pump with one
or more impeller and diffuser with the
addition of a jet ejector.
This operation is based on Bernoulli’s
principle, which state that an increase in the
speed of a fluid is accompanied by a decrease
in its pressure.

ADVANTAGES
• Simple structure, small size, light weight
and low price
• No moving parts or mechanical parts that
wear
• Long run life
• Capable of high production rates
• Low maintenance coasts
• Easily and quickly retrieved end replaced
when maintenance is required
• Can be used in wells with high deviation
angles without causing damage to the
tubing
• Simple structure, small size, light weight
and low price
DISADVANTAGES
• Lower efficiencies than other forms of
artificial life resulting in higher horse
power requirement for the power
requirement for the power fluid pump
• Power fluid injection rates are typically
twice the production rate
• Space limitations, especially for offshore
installations
• High pressure surface lines
