Pneumatic diaphragm pump is a new type of transport device, used to transport various materials like liquid, slurry, powder, even of high viscosity, volatile, flammable, highly toxic liquid
Advantages:
1) can work under bad air source, the reversing valve is reliable, not easy broken.
2) smooth air path, no air path obstacle from 1/2'to 3'pump,ensuring a flexible reversing.
3) Reversing valve totally externally maintainable.
4) Less moving parts compared to other diaphragms pumps.
5) pilot type reversing valve with long working life, ensuring the continuous running.
6) one reversing valve suits to different size pumps.
Application:
The diaphragm pumps can be applied to ship/bus/train unloading, chemical production, batch treatment and mixing, large tank or tank area conveying, common feed-conveying, system flushing, wastewater treatment or fluid filtration, packaging or filling, recycling and recycling.
