Lutz air driven double acting diaphragm pumps. The pumps are typically abbreviated AOD (air operated diaphragm pumps). The pumps typically have a small footprint and are lightweight in construction, while offering high performance in terms of both capacity and pressure. Although the pump is a positive displacement pump, the pump can be shut off on the media side during operation without damaging the pump. However, for other reasons it is recommended to cut off the pump from the driving air.
Use: In all industries and for all media. Special models are available for food. Double air operated diaphragm pumps are typically cheap to purchase and easy to service.
However, it should be noted that due to operating costs associated with air production, the pump is best suited for short-term operation.
