18. Configurations There are 4 different configurations in the FreFlow range Type FRE Pump with bearing bracket Type FRES Pump with stub shaft and lantern piece coupled to an IEC flange motor Type FREF Pump with lantern piece coupled to a flange motor with extended shaft end Type FREM Pump with stub shaft and lantern piece coupled to a petrol or diesel engine Construction Pump casing and impeller The pump casing is a combination of a volute and aeration chamber to ensure the selfpriming action There is a generously sized drain hole at the bottom of the pump casing which can also be used for cleaning Dependent on the pump size the pump is fitted with a half open or closed impeller The half open impellers have 3 or 4 blades with a generously sized passage Pumps with a half open impeller come with a renewable wear plate between pump casing wall and impeller blades Pumps with a closed impeller have a renewable wear ring fitted in the pump casing around the impeller entry This wear plate wear ring enables the pump to be overhauled at minimum cost Bearing bracket construction In the FRE configuration pumps are fitted with a shaft supported in two generously sized grease lubricated ball bearings Pumps of the FRES and FREM types come with a stub shaft which can be mounted on the mother shaft without play Pumps of the FREF range have the impeller fitted on the extended motor shaft In the FRES FREF
