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.
An electric fuel pump is an essential component which can be found in your car. The fuel pump is used to make sure the natural gas or propane travels through to the engine. The fuel must travel through a hose, also called the fuel line, and it is the job of the fuel pump to make sure the gas reaches the proper location.tep 2 - Flip the Switch. There should be a prime switch located on the fuel pump line. Flick the switch to prime the fuel pump. You can prime the fuel pump a couple of times but do not leave it in the on position.
