Product Overview
SANDPIPER Diaphragm is the flexible membrane that separates the compressed air chamber from the fluid chamber in an air-operated double-diaphragm (AODD) pump. Two diaphragms are connected by a common shaft. As compressed air is alternately directed to each diaphragm chamber, the diaphragms flex back and forth, creating the pumping action that draws fluid into and expels fluid from the pump chambers.
The diaphragm is the highest-wearing component in an AODD pump because it is subjected to continuous flexing, pressure cycling, and chemical contact with the pumped fluid on the fluid side. A diaphragm failure typically results in fluid leaking into the air side of the pump, air bubbling into the fluid, or complete pumping failure.
SANDPIPER replacement diaphragms are available in a range of materials to handle different fluid chemistries, temperatures, and flex life requirements: elastomeric diaphragms (rubber or thermoplastic) and PTFE diaphragm designs with or without a back-up diaphragm. Most SANDPIPER pump models use multi-layer elastomer diaphragms or a PTFE-faced diaphragm with an elastomer backer.
Our SANDPIPER replacement diaphragms are manufactured using precision compression molding or thermoforming, cured to the specified durometer hardness, and dimensionally verified for bolt hole pattern, diaphragm OD, and flex zone thickness.

Why Choose Our SANDPIPER Diaphragms
- Dimensional Accuracy — Diaphragm OD, bolt hole pattern, and center hole are precisely matched to the original SANDPIPER specification for correct clamping and sealing
- Material Traceability — Each diaphragm batch is traceable to the raw material lot, with durometer hardness and tensile strength records maintained
- Fabric-Reinforced Options — For high-pressure or high-cycle applications, fabric-reinforced elastomer diaphragms offer extended flex life compared to homogeneous designs
- PTFE + Elastomer Backer — One-piece PTFE-faced diaphragm with bonded elastomer backer provides the chemical resistance of PTFE on the fluid side with the flex resilience of elastomer on the air side
- FDA & 3A Available — FDA-compliant and 3A-certified diaphragm materials available for sanitary and food-grade SANDPIPER pump models
