I-PASS Co., Ltd. is a manufacturer specializing in composite materials and supplies Vertical Pump Bearing, Centrifugal Pump Bearing, Hydraulic cylinder SEAL KITS and Rudder Pintle & Stern Bearing for ships for domestic and export. We are committed to research and development of new products in order to develop lighter, stronger, tough and nature-friendly composite material technologies for replacing metal materials resources are limited

In 2009, I-PASS completed the development of non-lubricated composite bearings for ships and acquired classification certification in eight advanced countries. Since then, we have been supplying rudder pintle, carrier and disk bearings to Daewoo Shipbuilding & Marine Engineering Co., Ltd., Samsung Heavy Industries Co., Ltd., and Daehan Shipbuilding Co., Ltd., as well as stern bearings to small and medium-sized shipbuilders. We have been strengthening PR in overseas markets and spurring exports as well.

In 2010, we jointly developed bearings for CWP, SLP, SCWP, and COP seawater pumps using composite materials with five thermal power plants (Korea Midland Power / Korea Southern Power / Korea Western Power / Korea South-East Power / Korea East-West Power Co., Ltd.) and received the “Excellent” grade in the completion evaluation. Since then, we have been supplying composite material pump bearings for seawater and wastewater to five thermal power plant companies (South-East Power Co., Ltd., Korea Southern Power Co., Ltd., Korea Midland Power Co., Ltd., Korea Western Power Co., Ltd., and Korea East-West Power Co., Ltd.) as well as to local district heating corporations and pump makers.

In 2020, we completed the development of a non-metal, high-performance composite material wear ring (LUNA-CAPA) for centrifugal pumps with the Korea Water Resources Corporation through a performance-sharing task, and in 2021, we acquired the Innovative Product certification in the SOC technology market. LUNA-CAPA wear rings can greatly contribute to low carbon and eco-friendliness by increasing pump efficiency, reducing pump vibrations and costs, and extending maintenance cycles.

In 2025, I-PASS acquired Innovative Product certification for composite vertical pump bearings (CWP, SLP, COP, SCWP, ACWP, MCOP)

In order to discover future materials that can replace metal, finite resources, and to development lighter, stronger, more durable, and more environmentally friendly composite material technologies, all employees of I-PASS firmly promise to pursue creation with an indomitable will and to face challenges with persistence and perseverance.
