All-Flo diaphragm or AODD metal pump’s working principle is self-priming. It can pull or suck liquid into pump itself. ALL-FLO Diaphragm Metal Pump In addition, flow rate and pressure rate are adjustable. It is designed to be robust and durable. With footprint, it makes installation easier. For better performance, it must be used in conjunction with air compressor. It can be disassembled for cleaning. It can provide 120 psi (8.2 bar) maximum pressure. Aluminum and anodized aluminum material offer medium corrosion and abrasion resistance, while stainless steel is suitable for application that requires higher chemical and abrasion resistance. It can be used with all kinds of liquid such as chemical, oil, sludge, viscous liquid, food and beverage, medicine, etc.
