DELT Diagram Pump, an air-operated dual diaphragm pump is designed for pumping water and wastewater from service stations and for use in the chemical industry. This positive displacement pump uses compressed air as a power source and features two diaphragms. Compressed air drives the pump to provide consistent suction and discharge, making it easy to pump liquids. Additionally, it is very safe in hazardous environments since it does not use an electric motor. The DELT air-operated double diaphragm pump can transfer not only free-flowing liquids but also viscous mediums. It offers the advantages of self-priming, submersible, shielded, solution, and contaminant pumps, among others.
