It passes solids to 5\/16\" (8 mm) and handles fluid to 212°F (100°C).\u003c\/p\u003e\u003cp\u003e316 stainless construction is specified where corrosion resistance and cleanability both matter — dairy, brewing, fine chemicals and pharmaceutical transfer. Santoprene diaphragms and balls offer broad chemical compatibility with a long flex life, and are usually the best value where the duty cycle is heavy. Ball check valves are the right choice for flooded-suction installations.\u003c\/p\u003e\u003cp\u003eAir drive means no electrics at the pump, seal-less operation with nothing to leak at a shaft, and safe stalling against a closed discharge.\u003c\/p\u003e\u003cp\u003eWe ship from Texas, quote honest lead times and price sharply.
