The Sandpiper 1 1/2" 38mm FDA Air-Operated Double Diaphragm (AODD Pump) is an ideal positive displacement pump for hygienic applications in industries such as the pharmaceutical industry, food and beverage industry, chemical industry or cosmetic industry especially when electropolished surfaces are involved. 

This type of ball valve pump is robust and reliable even when it comes to tough environments. It is easy to maintain as it comes with a band clamp and wing nut fasteners enabling quicker teardowns and reassembly. Not only that, the parts of this series of positive displacement pumps are interchangeable with older AODD technology, minimising your cost while replacing it.
