It passes solids to 1\/16\" (2.0 mm) and handles fluid to 180°F (82°C).\u003c\/p\u003e\u003cp\u003eA 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. 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\u003eBeing air-driven, it needs no motor starter or electrical classification at the pump, self-primes from dry, and can be dead-headed and left stalled under pressure.\u003c\/p\u003e\u003cp\u003eStocked and shipped from Texas with fast dispatch and competitive pricing.
