*** Topic – Jet pump ***
Goals of the presentation
Following will be discussed-
1) Definition of jet pump
2) Introduction
3) Construction {main parts}
4) Working of jet pump
5) Installation
6) Merits
7) Demerits
Definition – “The pump in which a small
jet of steam , air water or other fluid in
rapid motion lifts or otherwise moves by its
impulse a large quantity of the fluid with
which it mingles.”
Or
Construction:- It consists of following main
parts-
1. Strainer
2. Foot valve
3. Ejector assembly
4. nozzle
5. Venturi
6. Pressure switch
7. Regulating pressure gage
8. Motor
9. Centrifugal pump
10. Impeller
WORKING
INSTALLATION
The following items are needed to install a jet
pump –
• Jet pump [ and injector for a deep water well ]
• Pressure tank
• Well seal
• Wrenches
• Cutter
• Sealing tape/ pipe thread compound
• Pipe/fitting
• Derrick and winch
 Merits :- 1. It is lite in weight,
2. easy to install,
3. No moving parts or
mechanical parts that wear,
4. Long run life,
5. low maintenance cost,
6. capable of high production
rate.
Demerits : 1. lower efficiency {25-30%}.
2. power fluid injection rates
are typically twice the
production rate.
3. space limitation, especially
for offshore installation.
4. compressed air or steam is
required to run it, hence
the running cost of jet
pump is high
Application:-
Suction of muddy water,
Mining,
Suction water from small bore well.
