TM 10-4330-237-13&P GLOSSARY Bonding 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 bonded units. Coalesce To grow together. To unit into a whole. To cause small droplets of water to unite into larger drops. Coalescer Element 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. Defective Condition of a part that prevents the part from performing its intended function, caused by normal aging, accident or manufacturing imperfection. Deterioration Condition of a part caused by weathering, excessive heat, excessive cold, chemical action, etc. Differential pressure 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). Dry break Separation of couplings without loss of fuel. Emulsion A dispersion of fine water droplets in the pumpage. Grounding 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 effectively grounded. Malfunction Failure to operate in a normal manner. Monitor To observe a condition or operation such as that indicated by an indicator light or meter. Pumpage The fluid being pumped by the fuel transfer pump. Separator Element A filter element that repels coalesced water droplets. The pumpage flows from the outside to the inside of the element. Glossary-1/(Glossary-2 blank)
