UL Field Inspections. Yesterday we were greeted at the front door by our UL Inspector for an unannounced field inspectionâ¦surprise! At another facility there might be a cry for alarm, but at Coast Label Company there was no mad scramble, no rush to hide this, or go find that. We just sat him down and asked what he was checking today.
Jet pumps create suction in a rather novel way. The pump is powered by an electric motor that drives an impeller, or centrifugal pump. The impeller moves water, called drive water, from the well through a narrow orifice, or jet, mounted in the housing in front of the impeller.
Jet pumps are a type of home water well pump that is used for lower flow rates than vertical turbine types. It is a horizontal end suction pump, put makes use of an ejector to assist the flow. Horizontal end suction pump with ejector either mounted on the pump (for shallow well services), or located down in the well.
