The Sandpiper line of Heavy-Duty Flap
Valve Diaphragm Pumps are engineered to pump larger solids than traditional
diaphragm pumps that have ball valves. These air-operated diaphragm pumps
work well with abrasive slurries and viscous sludge. They handle up to 2”
solids and have a unique bottom discharge port that offers superior suction
lift and avoids damage from settling solids. Thick-walled constructions
and heavy-duty pump features make these Sandpiper pumps particularly rugged for
long-life and extended wear.
