The DP-15FPT is Yamada's 1/2" air-operated double-diaphragm pump in polypropylene, with a 7.4 GPM maximum. It passes solids to 1/32" (1 mm) and handles fluid to 180°F (82°C).
A glass-filled polypropylene wetted path handles dilute acids, alkalis and brines without the galvanic issues a metal body brings, making it the usual pick for chemical transfer and wastewater duty. 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.
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.
Texas-based, with short lead times and pricing that reflects our supply position. Not sure this is the right build? Send us the fluid and duty and we will confirm.
