QBY3, the third generation pneumatic diaphragm pump, has six main merits, such as, reliable quality, long life expectancy, low noise, small vibration, and non-crash fault, high exquisite workmanship, which had been researched and developed by our teams in our company.

QBY3 has the following characteristics: 
Water irrigation and diversion are not necessary; its self-suction capacity can reach 5 odd meters with head of delivery up to 70m and discharge pressure above 7 bars.
Enjoying excellent passing performance even can pass through easily particle and slurry whose diameter below 10mm. They can handle sludges and slurries with a relatively high amount of grit and solid content.
Head of delivery and flow could adopt stepless regulation through controlling the valve switch.
There is no rotating parts, no seal. The medium must not be leaked out because the diaphragm has separated the transmitted medium from transmission machine. Suction and transmission of various special mediums, such as various toxic, strongly acidic, volatile liquids without any damage to the environment and man;

It is safe to use at flammable and explosive places for without using the electricity.

It can be running and working when immersed in the transmitted medium. 

It is great convenient of user-friendly, reliable, and easy operated by switch on and off, and even idle load running. It will be stopped automatically to reach self-protect performances and running automatically after being in a natural load.

Its simple construction and lower easy deactivated spares are easy to install and maintain. The transmitted medium will not contact with the distributing valve or connecting rod and other moving parts, which is unlike other types of pumps with an easy deactivated spares like rotors, piston, gears, vanes.

It can handle highly viscous liquids (viscosity under 10,000 centipoises)
One of the most noticeable characters is that no any damage to the machine by dry running and no any oil lubrication are used.
Plastic flange pressure: PN 0.6mpa (10bar); Metal flange pressure: PN 1.0mpa (10bar).
