All-Pumps Chemical Pump – Durco Polychem S-series Non-Metallic

PRINCIPLE OF OPERATION

Industrial Chemical Pumps

In Durco PolyChem centrifugal pumps, fluid enters the impeller through the “eye” and is “centrifuged” (hence the name) to the impeller periphery. As the impeller rotates, it imparts kinetic energy onto the fluid. The impeller vanes have channels with an increasing flow path area. As the flow path area expands, the passing fluid’s velocity decreases and the pressure increases. The fluid then falls to the volute. Due to the unique shape of the volute casing, the fluid undergoes a further velocity decrease and pressure increase. This causes the liquid to be discharged through the discharge port.

Description

The PolyChem S-Series chemical process pumps are powerful workhorses suitable for handling highly corrosive fluids. These non-metallic centrifugal pumps are lined with a flexible fluoropolymer, resulting in superior temperature tolerance and corrosion resistance. The S Series is designed according to the dimensional standards of ASME B73.1, ISO 2858/5199, and JIS drilling, making it adaptable to many different applications.
