A high performance sea water pump for a deep submergence research vehicle has been developed. This pump is small in size, light in weight, and capable of pumping 41/min. under the waser pressure equivalent to the depth of 6000m and operates at the high speed of 2250rpm. The pump is a three-throw reciprocating type with self-aligning plungers, and clearance seals. The pumping efficiency is 79% at the dischare pressure of 630kgf/cm^2, and the leakage from plunger seals is only about 60cc/min and was stable at the durability test for 500 hours. In order to develop the sea water pump, various studies as shown were performed. l) feasibility study on pump types 2) screening tests of plunger and cylinder liner for various material combinations of ceramics. 3) study to improve the manufacturing accuracy of plunger and cylinder liner. 4) photo-elastic stress analysis of valve block. The development of the pump of this kind shall be a great contribution to the 6000m deep submergence research vehicle project.
