Energy Savings Device regulates AODD pump operation.
Designed to help conserve energy used by air operated double diaphragm (AODD) pumps, MizAir® uses fuzzy logic to analyze each stroke of pump and learns its unique characteristics. This electro-pneumatic smart device automatically makes internal adjustments to reduce pump's air consumption, consequently reducing energy required to run pump with little to no effect on its throughput, fluid flow,...
