Shop All-Flo™ Bunalast™ AODD Pumps
All-Flo™ AODD pumps with Bunalast™ diaphragms use a thermoplastic-elastomer (TPE) diaphragm engineered for long flex life and durability in high-cycle duty. Bunalast pairs the resilience of a TPE with good resistance to oils and many petroleum-based fluids, making it a longer-wearing alternative to standard nitrile in demanding transfer applications. The PSG® Store ships these pumps factory-direct with genuine All-Flo parts. Browse the Bunalast range below, or filter by body material, port size, and flow rate to match a pump to your fluid and duty cycle.
