Yamada builds the NDP-5FPT as a 1/4" double-diaphragm pump in polypropylene, capable of 3.4 GPM. It handles fluid to 180°F (82°C).
The glass-filled polypropylene wetted path resists most acids, caustics and salt solutions, which is why plastic-bodied units dominate plating lines, water treatment and chemical dosing. 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. Flat check valves are the right choice where the pump has to lift liquid rather than being fed by gravity.
The pump self-primes, handles a degree of entrained air, and holds pressure when stalled, which makes it forgiving on transfer duty that starts and stops.
