No Name Pump Annular Casing 18493 A26221 GGG403 355 X 340 X 140 DIN2501 PN16

Description:

The No Name Pump Annular Casing is a cast iron pump housing used in centrifugal and process pump systems to contain the impeller and direct fluid flow through the pump. Commonly installed in water treatment plants, chemical processing facilities, industrial circulation systems, and manufacturing equipment requiring durable pressure containment and efficient hydraulic performance. Maintenance teams, pump repair specialists, and OEM service technicians use this casing for pump rebuilds, equipment repairs, and replacement of worn or damaged pump housings.

Applications:

The No Name Pump Annular Casing is designed to provide pressure containment and fluid flow management in industrial pumping environments. It is commonly used in centrifugal pumps handling water, process fluids, cooling water, and light chemicals where corrosion resistance, structural strength, and compatibility with DIN flange standards are required. The casing is manufactured from GGG40.3 ductile iron and features DIN 2501 PN16 flanged connections for integration into European-standard piping systems.
