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.
Submersible Water pump: It is a very wide range of water treatment tools. The difference is that it works in the water, while the pump works mostly on the ground. A submersible pump has a sealed motor closely coupled to the pump body and pushes water to the surface. It functions via its assembly that is wholly submerged in the fluid to be pumped whereas a centrifugal pump uses a rotating impeller to increase pressure of a fluid.
