It passes solids to 5\/16\" (8 mm) and handles fluid to 212°F (100°C).\u003c\/p\u003e\u003cp\u003ePVDF construction handles the aggressive oxidising chemistry — chlorine, bromine, strong mineral acids — where polypropylene reaches its limit. 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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eStocked and shipped from Texas with fast dispatch and competitive pricing.
