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.
A drum pump, also called an oil drum pump or oil barrel pump, is used to remove liquids from barrels, drums, tanks, and intermediate bulk containers (IBCs). Drum pumps consist of an intake tube, a pumping mechanism, an outflow hose, and often a nozzle of some type. Drum pumps come in many forms from the rotary type to a variety of other styles including lever, piston, siphon, double diaphragm, electric, and air. The 55 gallon drum pump is most common, because it is a standard drum size. The intake valve of a 55 gal drum pump is inserted into a bung hole, and the pump sits atop the barrel. The siphon drum pump, lever-action, and rotary drum pump, due to their simplicity, are the most commonly used type of 55 gallon drum pumps. An electric barrel pump reduces the time required to dispense liquids.
