Frequently Asked Questions
Flowland supplies valve balls, valve seats, diaphragms, O-rings, gaskets, and repair kits compatible with Graco® AODD pumps — in materials including Santoprene™, Hytrel®, PTFE, Buna-N, and EPDM.
Material depends on your fluid type and operating conditions. Santoprene™ is a general-purpose choice; PTFE offers excellent chemical resistance; Hytrel® provides abrasion resistance. Contact Flowland for a recommendation.
Follow Graco's maintenance schedule and inspect diaphragms regularly for cracking, deformation, or leakage. Over-pressurization above the rated maximum will accelerate wear.
