Since 1990, SARAMAC has been exporting Kurimoto’s submersible sand pumps as well as the systems to Korea, Singapore, and Oman. The recent projects were done on June 20, 2017 and March 12, 2018 as the tests run were successfully completed in Korea.
The submersible sand pumps with 900kw & 1,100kw motors are installed on the vessels and used for extracting a good quality of sand from deep seabed. Kurimoto Ltd. is the only and leading company for this sea sand extraction system.
The submersible motor, which drives the pump, uses a double mechanical seal made of special cemented carbide for the shaft seal. The bellows type pressure regulates the submersible motor for internal pressure higher than the sea water pressure. With the robust design, the pump can work up to 100m deep in water with the reliability in preventing intrusion of sea water.
SARAMAC will continue working with Kurimoto Ltd. in searching for the market of sea sand extraction.
