CONVERTIBLE WELL PUMP INSTALLATIONS
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:
* Performance shown in GPM (gallons per minute) at 40 PSI (pounds per square inch) discharge pressure.

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 nger 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)
(Fig. A)
(Fig. B
5. Tighten the venturi tube in the casting nger
tight and one quarter additional turn with
wrench or pair of pliers.
6. Mount the ejector on to the convertible well pump
placing the gasket between the ejector and the
jet pump’s body (Fig. B).
7. Secure the ejector to the
pump body with the bolts
provided with the ejector kit.
8. Ensure the bolts are tight.
9. You have now completed
assembling the convertible jet
pump for shallow well applications.
10. Install the pump and the balance of the pump
accessories, i.e. tees, gauges, etc by following
instructions associated with gures 1, 2, and 3.
