Yamada's NDP-20BAT is a 3/4" AODD pump in aluminum, moving up to 31.7 GPM. It passes solids to 1/16" (2.0 mm) and handles fluid to 212°F (100°C).
Aluminium construction handles solvents, lubricating oils and hydrocarbon-based fluids well, and takes mechanical abuse better than a plastic body in a busy plant. PTFE diaphragms and balls give near-universal chemical resistance, covering solvents, concentrated acids and oxidizers that destroy rubber elastomers, at the cost of a slightly lower displacement per stroke. Ball check valves are the right choice for flooded-suction installations.
Air drive means no electrics at the pump, seal-less operation with nothing to leak at a shaft, and safe stalling against a closed discharge.
