Why Choose This Diaphragm

The diaphragm is the core wear component of your ARO air operated diaphragm pump — it flexes continuously to displace fluid through the pump chambers while maintaining a leak-free seal between the air and fluid sides. A worn, cracked, or ruptured diaphragm causes fluid bypass, loss of prime, reduced flow rate, and potential contamination of the air supply. This replacement unit delivers:

• Consistent fluid displacement – Engineered to maintain correct flex characteristics, chamber seal integrity, and flow performance for your ARO EXP series PD30A-X pump
• Exact-fit installation – Direct replacement with correct diaphragm diameter, bolt pattern, and material compatibility for the 3″ pump housing
• Durable construction – Built to withstand continuous flexing cycles, chemical exposure, and the demanding fluid transfer conditions of industrial pump operation
• Cost-effective solution – Aftermarket quality at a fraction of dealer pricing

Package Contents

• 1 × Diaphragm 94090-T

Essential for pump maintenance and diaphragm replacement. Keep your ARO 3″ EXP series PD30A-X air operated diaphragm pump transferring fluids efficiently, reliably, and leak-free on every job.
