Applications

Double diaphragm pumps transfer corrosive chemicals, solvents, and abrasive fluids in manufacturing facilities, water treatment plants, and laboratory settings. These pumps handle materials that would damage centrifugal or positive displacement pumps. Commonly used for batch processing, tank filling, and chemical dispensing where pneumatic operation is preferred over electric-driven alternatives.

Condition: For Parts or Not Working
This Ryan Herco Airgo 6220 Type 355 Double Diaphragm Air Powered Pump is being sold AS-IS for parts or repair. A crack in the plastic air line prevents the pump from building sufficient pressure to operate. The pump has not been tested beyond confirming this defect, and no functionality is guaranteed. The polypropylene body and stainless hardware appear intact with normal wear for a used pump; no obvious structural damage to the main pump body is visible in the photos. This unit would be suitable for someone looking to rebuild, harvest diaphragms or valves, or use it as a parts source. Please view our photo set and contact us if you have any questions.
