SS316L Stainless Steel Chemical High Suction Head Slurry Electric Battery Aro Diaphragm Pump

The SS316L stainless steel Aro diaphragm pump, a high-suction electric/battery-powered pump for chemical and industrial slurries, is driven by a motor or battery to reciprocate the diaphragm for media transport. When the diaphragm moves outward, the pump chamber volume increases, drawing liquid in through the suction inlet; when the diaphragm moves inward, the liquid is forced out through the pump outlet. A check valve within the pump body ensures unidirectional flow of the media, preventing backflow. The high suction head design guarantees stable delivery even at low liquid levels or high head, making it suitable for transferring corrosive, particle-containing, or high-viscosity chemical and industrial liquids. Furthermore, the diaphragm is completely isolated from the drive unit, ensuring safety and leak-proof operation.

1. Constructed from SS316L stainless steel, providing excellent corrosion resistance and durability for handling aggressive chemical slurries and liquids.
2. High suction head design enables efficient liquid transfer from low-level tanks or long suction distances without cavitation issues.
3. Electric or battery-powered operation allows flexible deployment in areas without compressed air, supporting mobile or remote applications.
4. Diaphragm-driven mechanism isolates fluid from moving parts, preventing contamination and ensuring safe, leak-free operation.
5. Easy maintenance and robust construction ensure long service life, reliable performance, and minimal downtime in demanding industrial environments.

Stainless Steel 0.55kW–22kW pneumatic diaphragm pumps are widely used in the chemical industry for conveying acidic and alkaline liquids and solvents, in the food and beverage industry for conveying slurries, syrups and juices, in the pharmaceutical industry for transferring liquid raw materials and intermediates, and in environmental protection and water treatment systems for conveying sewage or suspensions.
