Based on accumulated technology and quality, it stably supplies products to leading domestic and international plant companies and oil refineries.

"The pride of producing pumps, which are the foundation and core of the plant industry, is the driving force that has made Dongyang Chemical Machinery Co., Ltd. what it is today. Our challenge to create new legends will continue, and we will stand tall as a global leader in the pump industry through endless research and development."

Business Areas

• Oil Refining and Petrochemical Plant Pump Business: We design and manufacture process pumps for ultra-high temperature and high-pressure hydrocarbon transport that meet the strict standards of the American Petroleum Institute (API 610/685) using our own technology. We maximize facility safety and operational efficiency by supplying customized pumps specialized for major domestic and international oil refining and petrochemical processes.
• Special Industrial Pump and Power Generation Equipment Business: We supply high-value-added special mechanical equipment, including non-API centrifugal pumps for general chemical processes, sealless magnetic drive pumps, and long-shaft pumps for hydroelectric power plants. We provide localized liquid transport solutions that meet various industrial process requirements.
• Global Plant Engineering and Import/Export Business: Registered as a partner for overseas oil refining and energy public enterprises in the Middle East, Southeast Asia, and other regions, we export our self-manufactured pumps to plant projects in over 30 countries worldwide. We comprehensively perform technical reviews and engineering support services required for field application.

Products

• API 610 Centrifugal Pumps for Petrochemical Processes: These are industrial process pumps designed to safely transport flammable materials or hydrocarbons in high-temperature and high-pressure environments. Manufactured in single-stage and multistage structures (TSP, TDP, TSMP, etc.), they demonstrate excellent durability even under the harsh conditions of oil refining processes.
• API 685 Sealless Magnetic Drive Pumps (TMP/MAP, etc.): These are eco-friendly safety pumps that fundamentally block the external leakage of hazardous chemicals or toxic fluids by using magnetic force for operation without a shaft sealing device. They strictly satisfy the environmental regulations and safety standards of chemical and oil refining plants.
• Special Chemical Process Pumps and Mechanical Equipment: These are industrial pump facilities customized to client process conditions, such as corrosion-resistant and wear-resistant chemical pumps and long-shaft pumps. They are widely used in power plants, wastewater treatment, and general chemical manufacturing processes.

Special Notes

• Registered Approved Vendor for Global Oil Majors: The company is registered as an officially approved partner for global energy companies such as Saudi ARAMCO, PETRONAS, and PERTAMINA, as well as major domestic conglomerates. This signifies that its world-class quality standards and technical capabilities have been officially recognized.
• Localization Technology for High-Difficulty Special Pumps: The company has localized core technologies such as high-temperature/high-pressure multistage pumps and large long-shaft pumps, which previously relied heavily on foreign imports, through national research projects. It holds international standard certifications including ISO 9001, ISO 14001, and ISO 45001, ensuring a thorough quality and safety system.
• Engineering Know-how with Over 40 Years of Experience: Since its establishment in 1984, the company has accumulated vast design data and field experience by focusing solely on the pump sector. It continues to invest in smart factory construction and the development of patented technologies through its own technical research institute.

Recruitment Information

• Main Hiring Positions: Pump design and technical review (2D/3D CAD), production processing and mechanical assembly, technical sales, overseas sales, quality control
• Benefits: Four major social insurance plans, severance pay, company cafeteria (lunch and dinner provided), dormitory operation, commuter bus service, overtime and holiday pay support

💡 A Word from JOBPLOY
Dongyang Chemical Machinery Co., Ltd. is a manufacturer that handles precise and heavy pump equipment used in oil refining and petrochemical plants.
