Electrically connecting units before operations begin in order to equalize any static potential that
might exist and to provide a continuous path for any static potential that might be generated after
operations begin. Static potential is eliminated or prevented by grounding one or more of the
To grow together. To unit into a whole. To cause small droplets of water to unite into larger
A filter element designed to remove solid contaminants, and to break the emulsion of water in the
pumpage into large droplets. The pumpage flows from the inside to the outside of the element.
Condition of a part that prevents the part from performing its intended function, caused by normal
aging, accident or manufacturing imperfection.
Condition of a part caused by weathering, excessive heat, excessive cold, chemical action, etc.
Difference between inlet and outlet pressure at a filter or pump. An increase of differential
pressure indicates a restriction or blockage in the unit (e.g., a build up of sediment in a filter).
Separation of couplings without loss of fuel.
A dispersion of fine water droplets in the pumpage.
Connecting single or bonded units to a ground rod so that any static potential will be discharged
into the earth. If two or more units are bonded and one is grounded, the entire system is
Failure to operate in a normal manner.
To observe a condition or operation such as that indicated by an indicator light or meter.
The fluid being pumped by the fuel transfer pump.
A filter element that repels coalesced water droplets. The pumpage flows from the outside to the
inside of the element.
