Jinghai QBY3 Pneumatic Diaphragm Pump
QBY pneumatic diaphragm pump is a new‑type conveying equipment driven by compressed air. It works by reciprocating movement of double diaphragms. No electricity is required. It can handle media that conventional pumps cannot transport. The diaphragm separates fluid from pump parts, no shaft seal and zero leakage. It has self‑priming capability for slurry, mud, high‑viscosity liquid, corrosive media. Available in aluminum alloy, cast iron, stainless steel and PP plastic. Diaphragm and ball can be NBR, FKM or PTFE for different working conditions. Widely used in chemical, coating, mining, wastewater treatment, ceramic, food and pharmaceutical industries.
Product Features
1. Pneumatic drive, no power supply required. Auto‑stop when outlet is closed with overload protection.
2. Diaphragm isolation, zero‑leakage for toxic, volatile and corrosive fluids.
3. Strong self‑priming, no priming water needed. Can pass particles up to 10 mm for slurry and mud.
4. Flow and head adjustable by air pressure. Can run dry and be submerged in liquid without damage.
5. Multiple body and wetted‑part material options for different chemical environments.
6. Simple structure, easy maintenance. Only diaphragms and balls are wearing parts.
