Convertible
Jet Pump
A Convertible Jet Pump can be used either in shallow well applications, (0-25') or in deep well ap-
plications, (26' to 75'). Both measurements are from the intake port of the pump to the height of
the endd of the suction pipe. The pump can be converted shallow to deep or deep to shallow.
When properly installed your jet pump should provide the following performance:
Preparing the Convertible Jet Pump for Shallow
Well Application
1. Note the nozzle is used in both shallow well and deep
well applications and is installed in the ejector casting at
the factory (Fig. A).
2. The nozzle should be finger tight and one quarter of a
turn more using a wrench or a pair of pliers.
3. Select the venturi tube marked with the horsepower of
your pump motor, i.e. 1/2HP or 3/4HP etc, or marked
with "SW' denoting for shallow well applications.
4. Install the venturi tube in the ejector housing. (Fig. A)
