The NDP-20BSH-D covers 3/4" transfer duty as an air-operated double-diaphragm pump in stainless steel, rated to 31.7 GPM. It passes solids to 1/16" (2.0 mm) and handles fluid to 248°F (120°C).
A 316 stainless wetted path resists chlorides, organic acids and most process chemicals, and is the standard specification wherever wash-down or product purity matters. Hytrel diaphragms and balls carry the highest temperature rating in the range and resist abrasion well, which suits hot oils and particulate-bearing fluids. Ball check valves are the right choice for flooded-suction installations.
Supplied as a drum-mount package with dip tube and bung adapter. It self-primes, tolerates running dry, and stalls harmlessly against a closed valve, so it suits batching and intermittent transfer where a centrifugal pump would be a poor fit.
Stocked and shipped from Texas with fast dispatch and competitive pricing. Send over your application details if you want the material selection checked before ordering.
