Our general purpose metallic diaphragm pumps are available in three materials: aluminum, anodized aluminum, and stainless steel. AODD Pumps in aluminum and anodized aluminum offer medium corrosion and abrasion resistance, while stainless steel is suitable for applications that require higher chemical and abrasion resistance.
AYTC offers Air Operated Double Diaphragm pumps suitable for virtually any fluid transfer application. Since 1986, we have been providing customers with simple solutions for challenging applications.
