Heavy Duty Flap Valve

HDF Pumps are recommended for abrasive slurries, suspended and non-suspended solids and line-size solids. 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

lap valve pumps are especially recommended for slurries and liquids with suspended solids.

Flap valve pumps are especially recommended for slurries and liquids with suspended solids. Flap valves allow passage of line-size solids without damage of solid or pump shafts.
