Air-operated diaphragm pumps
Air-operated diaphragm pumps require a compressed air supply to drive them. If this does not already exist it can be very expensive to install. Even the best-maintained air supply systems are inefficient with at least 30% air leakage. The energy costs of supplying air for an AOD are much higher than for a shanghai remy valve & peristaltic pump. Air pressure limits the discharge pressure
