eatures of QBK diaphragm pumps:

1.No need for watering, suction range up to 5 meters, head up to 70m, outlet pressure6 bars

10mm.

2.The flow path is wide, good passage, allowing through the maximum particle diameter up to 10mm.When pumping mud and sludge, the pump wear is very little.

3. The head and flow rate can be adjusted through the air valve (pressure adjustment between 1 -7 bar).

4.The pump has no rotating parts, no shaft seal, the diaphragm separate the medium and moving parts completely, the medium will not leak. So when pumping toxic, volatile or corrosive media, there is no environmental pollution and endangering personal safety.

5. The pumps do not need to use electricity, safe and reliable for use in flammable and explosive places

6.Convenient to use, reliable in operation, gas valve can be simply opened and closed to start and stop the pump. Even if the pump runs without media for a long time or stops suddenly due to accidents, it will not be damaged. Once overloaded, the pump will stop automatically and has self-protective performance. Once the load returns to normal, it can restart automatically.

Simple structure and few vulnerable parts.

7.The structure of this pump is simple and easy to install and maintain. The medium being pumped does not come into contact with the gas valves, moving parts such as the connecting rod, unlike other types of pumps that experience a gradual decline in performance due to the wear of rotor, piston, gear, blade, etc.

8.Can convey relatively viscous liquids (viscosity below 10,000 cps).

9.This pump does not require oil lubrication and has no impact on the pump even if it idles, which is the most outstanding feature of this pump.

10.Pump can be made of many kinds of materials according to clients, like cast iron, stainless steel, aluminum alloy, PP, etc to meet customers' different requirements
