Frequently Asked Questions
Flowland supplies a full range of Sandpiper® compatible parts including valve balls, valve seats, diaphragms, air valves, O-rings, gaskets, pistons, shafts, mufflers, clamp bands, hardware sets, and complete repair kits — available in multiple materials.
The air valve is one of the core components of an AODD pump. It directs compressed air alternately to each diaphragm chamber, driving the pump cycle. Sandpiper® pumps use both internal and external air valve designs. The valve housing material — brass, aluminium, plastic, or stainless steel — is selected based on the application environment.
Diaphragms should be replaced at regular intervals as part of a preventive maintenance programme, following the manufacturer's recommendations. Regular inspection for cracking, deformation, or fluid bypass is essential to avoid unplanned downtime.
Material selection depends on the fluid being pumped, operating temperature, and chemical compatibility requirements. Santoprene™ suits most general applications; PTFE is ideal for aggressive chemicals; Buna-N for petroleum-based fluids; EPDM for dilute acids. Contact Flowland for a tailored recommendation.
