Jeongsin Machinery Co., Ltd. is a specialized manufacturer of mineral processing and special pumps located in Pohang, Gyeongsangbuk-do. We focus on the development and production of slurry pumps for power plant desulfurization facilities, mining machinery, and mineral processing plant equipment. Based on our long history, we possess expertise in the localization of parts and have a track record of supplying to domestic and international power plants and steel mills.

"Since our founding, we have been a company producing slurry pumps and mining machinery, along with the localization of slurry pumps. Based on our accumulated know-how, we have pursued continuous research, development, and quality improvement. In particular, in addition to the localization of slurry pumps for power plant desulfurization facilities, we possess excellent technical capabilities in the mineral processing field, such as securing superior slurry pump technology and graphite mine processing plants, and we are committed to the development of our client companies."

Business Areas

• Slurry Pump manufacturing and localization: We design and manufacture special slurry transport pumps used in thermal power plant desulfurization facilities and steel mill processes. We possess proprietary modules and core component localization technology suitable for environments requiring high corrosion and wear resistance.
• Mining machinery and crushing equipment production: We supply crushers and classification equipment used in mining, mineral processing, and smelting processes. We manufacture customized equipment that maximizes the efficiency and durability of mineral processing operations.
• Mineral processing plants and mineral processing engineering: We participate in graphite mines and public/private mining research plants to build comprehensive mineral processing plant facilities. We perform stable performance verification by introducing 3D design and flow analysis.

Products

• Desulfurization facilities and industrial slurry pumps: These are highly durable pumps with special structures and materials for transporting highly abrasive limestone, silica sand, and desulfurized gypsum. Designed with a double-split casing structure, they offer excellent convenience for assembly and maintenance.
• Crusher Equipment for mining: Industrial crushing equipment that effectively pulverizes mineral raw stones, steel by-products, and clinker. Wear-resistant parts are applied to withstand harsh operating conditions.
• Classifier & Cyclone: Equipment for mineral processing that precisely classifies minerals and powders according to particle size. Widely applied as main equipment in steel mills and power plant facilities.

Special Notes

• Capability in localizing core slurry pump components: Through 3D CAD and flow analysis technology, we have localized foreign pump components with our own designs. We contribute to shortening supply periods and reducing costs by replacing foreign parts.
• Supply references for major domestic power and steel companies: We have verified our reliability by continuously supplying equipment to major steel companies such as POSCO and public power generation companies including Korea Midland Power (KOMIPO).
• Global plant equipment export record: We have successfully supplied crushing equipment and pumps to overseas power plants and steel mills in Vietnam, Indonesia, and Brazil, gaining recognition for our technical prowess in international markets.

Recruitment Information

• Main Hiring Positions: Machining and assembly, material management and delivery, production site assistance
• Benefits: 4 major social insurance (National Pension, Health Insurance, Employment Insurance, Industrial Accident Compensation Insurance), severance pay

💡 A Word from JOBPLOY
As this is a machinery manufacturing workplace that directly produces and processes medium-to-large pumps and mining machinery, it is important to strictly adhere to on-site safety rules, such as using cranes, handling heavy objects, and wearing safety gear. It is suitable for foreign workers who want to build on-site technical skills, as they can learn the technology for machine assembly, parts processing, and plant equipment structure from the basics.
