AFS External Flex Assemblies provide a flexible connection between the pump chamber and the transport pipe. The flexible hose provides easy connection to transport pipe regardless of difficult alignments and also takes up movement caused by soil settling preventing the breakage of discharge piping. High and low pressure models are available to handle discharge pressures up to 200 PSI. External flex assemblies are built using all corrosion resistant materials and durable SCH80 PVC fittings.
