The SANDPIPER S20 2" (50mm) PVDF Containment-Duty Ball Valve AODD Pump is engineered for hazardous, corrosive, and environmentally sensitive fluid transfer applications where leak containment is critical. Built with PVDF wetted construction and Sandpiper’s containment-duty design, this air operated double diaphragm pump helps protect operators, equipment, and the surrounding environment by containing fluid in the event of diaphragm failure.
With a 2-inch universal ANSI / DIN flange port connection, high chemical resistance, and a maximum flow rate of up to 606 LPM (160 GPM), the S20 PVDF containment-duty pump is suitable for aggressive chemical transfer, acid handling, process chemical circulation, wastewater treatment, and industrial fluid handling applications.
PVDF provides excellent resistance to many corrosive chemicals, making this pump a strong choice for chemical processing environments that require dependable containment, long service life, and safe handling of difficult fluids.

Frequently Asked Questions
Why choose a containment-duty AODD pump?
A containment-duty AODD pump provides additional protection by helping contain pumped fluid in the event of diaphragm failure, making it suitable for hazardous, corrosive, or environmentally sensitive applications.
What is PVDF suitable for?
PVDF is suitable for many corrosive chemical applications and is often selected for aggressive fluids that require strong chemical resistance.
Can the Sandpiper S20 PVDF containment-duty pump run dry?
Yes. The pump is designed for run dry operation, helping reduce the risk of damage during intermittent or variable flow conditions.
Our engineering team can help you select the correct S20 containment-duty AODD pump, diaphragm material, and configuration based on your chemical compatibility, fluid properties, temperature, and operating conditions.
