Convertible
Jet Pump
A Convertible Jet Pump can be used either in shallow well applications, (0-25') or in deep well
applications, (26' to 75'). Both measurements are from the intake port of the pump to the water
source. 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. Use the large end of one of the venturi tubes as a
wrench to ensure the nozzle is tight in the ejector
housing. The nozzle should be finger tight and one
quarter of a turn more using a wrench, a pair of pliers or
the venturi tube.
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.
