Installations and applications:
- Self-priming centrifugal pumps, suitable for suction from deep wells, self-priming is achieved using an ejector, housed in jet body, which can be installed directly on pump body or more often lowered in a well and connected to pump body by two pipes
- Total delivery produced by closed centrifugal impeller is sent only partly to delivery opening, remaining water is recirculated through ejector, which is connected to suction chamber where it generates necessary vacuum to draw up water from point where jet body is immersed
- Water from jet body suction opening mixes in diffuser with re-circulating water from pump, thus increasing its pressure at expense of re-circulating water and is drawn into pump through suction pipe, when jet body is directly installed on pump body, those pumps will works like other normal jet pumps
- It is always advisable to install a foot/non-return valve on jet body suction opening and install a check valve on pump delivery opening to ensure adequate counter-pressure when working
- Fill pump, piping between pump and ejector body before starting up
- Those pumps should be installed in a covered area, protected against the weather
