Notes on the use of pneumatic diaphragm pumps

Pneumatic one-way diaphragm pump with reliable quality and long service life, low noise, low vibration, never die, fine workmanship and other six advantages, that is, to pump the flow of liquid, but also to transport some of the media not easy to flow, with self-priming pumps, submersible pumps, shield pumps, mud pumps and impurity pumps and other conveying machinery many advantages.

1, spacious flow, good through performance, allowing through the maximum particle diameter of 10 mm. Pumping mud, impurities, little wear and tear on the pump.

2、Pneumatic one-way diaphragm pumps do not need to be filled with priming water, the suction range up to 8.8 m, head up to 84 m, the outlet pressure ≧ 8.4 bar.

3、Pneumatic one-way diaphragm pump without rotating parts, no shaft seal, diaphragm and other pumping media and pump moving parts, workpiece media completely isolated, the media conveyed will not leak outward. So when pumping toxic, volatile or corrosive media, it will not cause environmental pollution and endanger personal safety.

4、Head and flow can be steplessly adjusted by the opening of the air valve (air pressure adjustment between 1 and 8.4 bar).

5, can be submerged in the medium work.

6, no need to use electricity, in flammable, explosive places to use safe and reliable.

7, pneumatic diaphragm pump structure is simple, less wearing parts, simple structure, easy installation, maintenance, the pump conveys the medium will not touch the air distribution valve, linkage and other moving parts, unlike other types of pumps due to rotor, piston, gear, vane and other parts of the wear and tear of the performance gradually decline;.

8, easy to use, reliable work, open and close simply open and close the gas valve, even if due to unforeseen circumstances and a long time without media operation or sudden stop pump will not be damaged, once overload, the pump will automatically stop, with self-protection performance, when the load back to normal, and can automatically start running.

9, pneumatic diaphragm pump without oil lubrication, even if idle, there is no impact on the pump, which is a major feature of the pump.

10, can convey more viscous liquid (viscosity below 25000 centipoise).

Special industries

Electronic grade pneumatic double diaphragm pump is specially developed for high-tech electronics industry and strong corrosive media by the whole machine all plastic material pneumatic double diaphragm pump. Its material PTFE, conductive PTFE, PE, conductive PE, SS316L, very suitable for high pollution, high risk, strong acid, low noise and clean room working environment in the use of pneumatic double diaphragm pump, especially the printed circuit board (PCB), semiconductor industry, packaging industry, ultra-strong corrosive transport and photoelectric industry and other high-tech industries are most suitable.

Since the nineties of the twentieth century, China's chemical industry and the rapid development of the domestic market, enterprises and manufacturers of corrosive media transport more demanding and demanding. The leakage of toxic and corrosive media greatly affects the safety of operators and environmental pollution. Electronic grade pneumatic diaphragm pumps can effectively prevent and solve such problems.

The product has an obstacle chamber system and a diaphragm detector, which generates a signal when the diaphragm is damaged and transmits it to the controller, which then issues a command for shutdown or alarm action.

(1) The barrier chamber system has two layers of diaphragms and two controllers. The diaphragm is filled with ultra-pure liquid. When the inner diaphragm in contact with the medium is damaged, the pumping medium and the ultra-pure liquid mix and change their conductivity, and this change is signalled to the controller by the sensor. When the outer diaphragm is broken, the signal is also sent to another controller via a sensor. This prevents damage to the diaphragm from causing serious consequences when the medium leaks.

(2) The diaphragm detector is a sensor installed in the silencer, when any side of the diaphragm is broken, the medium flows into the silencer, then the sensor can be sensed to transmit the signal to the controller for the relevant control.

Generally speaking, in conveying special or high-purity media to reduce as much as possible the media leakage and unnecessary pollution and waste, if necessary, through the use of electronic grade pneumatic diaphragm pump in the above two functions to ensure the safety of the operator, the environment and the pollution of the medium, so this kind of pneumatic diaphragm pump can be used in a large number of special chemical media transport. To provide a more convenient, safe and efficient solution for companies. I am convinced that in the coming years, the application area of electronic grade pneumatic diaphragm pumps in China will continue to expand, and if you encounter such problems, this product is an excellent solution for customers.
