Lube Oil Service Pumps News

Engineers at the Naval Ship Systems Engineering Station (NAVSSES), Naval Surface Warfare Center Carderock Division in Philadelphia recently oversaw the installation of dry flexible couplings on the lube oil service pumps and main feed pumps on USS Essex (LHD 2). The new couplings replace grease-lubricated versions eliminating hazardous waste and quarterly maintenance requirements for Sailors. The new couplings will run for a year on Essex before moving forward with installation on other amphibious ships. "The dry flex coupling, a device used to connect two moving parts of a system, replaced grid couplings that required more than three pounds of grease to keep each of the eight on board lubricated, " said Brett Franks, mechanical engineer and machinery alteration program manager.
