Product Description
The QA series air-operated diaphragm pumps are engineered for safe and reliable transfer of corrosive, viscous, and particle-containing liquids. Powered by compressed air, they offer flexible operation without electric motor exposure, making them suitable for hazardous and demanding working environments.
Their self-priming ability, dry-run capability, and solid-handling performance make the QA series an efficient choice for chemical transfer, drum unloading, wastewater handling, and industrial circulation systems. With corrosion-resistant construction and easy maintenance, the QA series delivers practical performance and dependable service life.
