Features and benefits:

• for transferring corrosive liquids in the chemical industry and chemical engineering
• the centrifugal impeller in the pump housing is driven by the drive shaft supported in the inner tube
• a mechanical seal in ceramic oxide/SiC, o-rings in FKM, separates the liquid from bearings and upper shaft
• a steel cored inner tube in PP or PVDF provides the ultimate in stability, preventing elongation of the plastic at high temperatures
• range of carefully chosen impeller diameters
• 2 sizes: 185 and 230 to meet varying capacity requirements
