Introduction
The QBK-15 Aluminum Alloy Air-Operated Double Diaphragm Pump (commonly abbreviated as AODD pump in the industry) is a positive displacement conveying device driven by compressed air. This size 15 model features a compact, lightweight design. Its entire body is cast from die-cast aluminum alloy, balancing light weight, wear resistance and cost-effectiveness. With no motor or shaft seal and zero electric spark generation, it can handle media containing solid particles, high-viscosity fluids, corrosive liquids, and flammable & explosive substances. Widely applied in chemical processing, coatings, wastewater treatment, printing, food auxiliary production, small workshop material transfer and other fields, it serves as a universal core fluid conveying equipment for small-scale working conditions.
