Add service kits for this pump

Wetted parts kit — K25-VE Diaphragms, balls and seats — the parts that wear with what you pump. $229.00 Air motor kit — K225-AM Air valve and centre seals — these wear with running hours, not with the fluid. $324.00

Ticked kits are added alongside the pump.

The NDP-25BVE-FLANGE covers 1" transfer duty as an air-operated double-diaphragm pump in kynar pvdf, rated to 46.2 GPM. It passes solids to 1/8" (3 mm) and handles fluid to 212°F (100°C).

Kynar (PVDF) resists concentrated acids, halogens and aggressive solvents that attack polypropylene, and carries a higher temperature ceiling than PP. EPDM diaphragms and balls handle acids, caustics, ketones and alcohols well — but not petroleum products, which swell the elastomer. Ball check valves are the right choice for flooded-suction installations.

Fitted with flanged manifolds rather than threaded connections. 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.

We ship from Texas, quote honest lead times and price sharply. Tell us the fluid, temperature and flow you need and we will confirm the right configuration before you order.
