All SANDPIPER® Heavy Duty Flap Pumps are configured with bottom discharge porting to prevent settling solids from shortening pump life and provide superior suction lift. HDF3-M/HDF4-M pumps are thick wall constructed of Cast Iron with elastomer and TPE (thermal plastic elastomer) diaphragms and check valves. See tabs below for a complete description.
