The Sandpiper® air valve is one of the main elements of an Air-Operated Double Diaphragm pump. Sandpiper pumps use both internal air valve and external air valve designs and locations. The materials used in the air valve body can vary in quality, such as brass, aluminum, plastic or stainless steel. In diaphragm pumps, the air valves are positioned between the diaphragms, right at the center of the pump. In this way, air passages and dead volumes are reduced to a minimum. HD Marine also provides its customers with the highest-quality spare part support compatible with Sandpiper.

A diaphragm pump operates on compressed air. The functional operation of the valve seats and valve balls, moving back and forth to pump the liquid, is what makes it work. Valve seats and valve balls are critical components for the proper operation of an air-operated double diaphragm pump. Valve balls and valve seats in Air-Operated Double Diaphragm Pumps are found in many sectors such as aerospace, environment, energy, automotive, construction, chemicals, ceramics, cosmetics, food and beverage, oil and gas, packaging, steel and metals, and pharmaceuticals.

As an important part of the general maintenance program, diaphragms should be replaced at regular intervals according to the manufacturer's recommendations. A double diaphragm pump uses two flexible diaphragms connected to each other by a shaft moving back and forth, and is also known as a positive displacement pump. The role of the diaphragms is to operate in a way that separates the air on one side from the medium on the other side.
