As appropriate gear pump systems for discharging low- to high-viscosity polymer melts from reactors and vacuum vessels under such circumstances as high-temperature, high-pressure, and high-viscosity, CW(R2) extraction gear pumps are awarded remarkable achievements by China Petrochemical International Company. Our different types of pumps have been widely employed in today's industries, for example, the production-lines with the capacity of annually producing five thousand ton HIPS, fifteen thousand ton SAN, five hundred ton SMA, three hundred ton K-resin, and five hundred ton ABS.


Operating Conditions



Viscosity: up to 20,000 Pa·S (20,000,000cP)
Temperature: up to 350 °C (662 °F)
Suction side: vacuum to 10 bar (145 psia)
Discharge side: up to 250 bar (3,625 psia)
The selection of pump speed depends on the operation conditions, i.e. viscosity, suction and discharge pressures,and characteristic of the product.
