Convertible Jet Pumps

Operating & Installation Instructions

Please read these instructions carefully. Failure to comply with instructions and designed operation of this system may void

the warranty.
Your pump has been carefully packaged at the factory to prevent damage during shipping. However, occasional damage

may occur due to rough handling. Carefully inspect your pump for damage that could cause failure. Report any damage to

your carrier or your point of purchase.
This pump is designed for shallow well installation for water level up to 25 feet, with injector installed on pump body; or for

deep well installation for water level up to 80 feet, with 1-1/4” pipes and injector down in the well. A pressure switch and

pressure gauge are standard features. The pump starts when the pressure drops to a cut-in setting (30 psi) and cut-out

setting (50 psi). The DuroJet Convertible Jet Pump can be mounted to either a pre-charged horizontal pressure tank or used

with a pre-charged free standing pressure tank. The pumps can also be used with conventional air to water tanks. For deep

well applications, replace the short tube in the ejector assembly to long tube #302922 (sold separately).
NOTE: Pre-assembled pump and pre-charged pressure tank packages are also available.
