Ocean Pacific Technologies (OPT®) manufactures and sells advanced, ceramic-enhanced, water lubricated axial piston pumps (APPs), axial piston motors, parts and packaged systems. APPs are the most efficient (up to 95%), light weight, compact and low maintenance pumps in their class. The APP combines the high efficiency of a positive-displacement pump with the low maintenance and smooth flow characteristics of centrifugal pumps. OPT’s pumps employ patented ceramic bearings, which for the first time allow the APP to work on unfiltered, low viscosity fluids such as plain water. And the APP can be efficiently and economically linked together in parallel to provide high pressure feed to almost any size system.
