SELECTING THE CORRECT
JET PUMP SYSTEM
It is important to determine which jet pump system you
need. A jet pump is a centrifugal pump with a jet (ejec-
tor) assembly. Goulds Water Technology sells three types
of jet pumps:
Shallow Well Jet Pumps with built-in jet assemblies for
maximum lift of 25'. See Fig. 1
Convertible Jet Pumps can be used for Shallow wells (to
25'), with a bolt on shallow well adapter; or deep well
(over 25') applications with a jet assembly in the well.
See Fig. 1, 2 and 3.
Deep Well Jets should only be used on deep well (over
25') applications with the appropriate jet assembly.
See Fig. 2 and 3
Use a shallow well pump or a convertible pump with a
Shallow Well Adapter for wells with a maximum suc-
tion lift of 25'. This 25' includes actual vertical lift plus
friction loss in the suction piping. Shallow well systems
are identified by one (1) pipe going to the well, lake or
river. They are good for city water booster systems and
pumping from cisterns or tanks. See Typical Installations,
Figs. 1, 5 and 6.
Deep well jet pumps are used for lifts greater than 25'
and must have two pipes going to the well. There are two
types of deep well jet assemblies, twin-pipe and packer
systems. Deep well pumps come in both vertical and
horizontal designs and in single and multi-stage models.
See Typical Installation Drawing, Fig. 2 and 3.
Consult with your Professional Dealer or Distributor to
select the best pump system for your application.
