Overview
The JYS series single-stage, two-stage, and three-stage heavy-duty petrochemical process pumps are horizontal, radially split, double-supported, centrifugal process pumps. They are designed according to API610 (8th edition) standard and comply with API610 (8th edition).
Application Range
The JYS series heavy-duty petrochemical process pumps were developed to meet the needs of China's modernization of petrochemical facilities and to quickly adapt to equipment upgrades centered on energy saving. They are products that conform to the international advanced standard API610 (8th edition) and employ a special design to meet the needs of more demanding and heavy-duty operating conditions. This type of process pump is used in petroleum refining, petrochemicals, and other industries to transport clean or slightly particulate petroleum, liquefied petroleum gas, and other products. Typical applications are in modern refineries.
Mainly Used For
• Crude oil transportation
• Low and high-temperature applications in refineries, petrochemicals, and coal processing industries
• Chemical industry, papermaking, pulp and paper industry, sugar industry, and general process industries
