QBK氣動隔膜泵是我公司開發的第三代氣動隔膜泵，具有使用壽命長，不會停頓等優點，
它既能抽送流動的液體，又能輸送一些不易流動的介質，具有自吸泵、潛水泵、屏蔽泵、泥
漿泵和雜質泵等輸送機械的許多優點。

1、不需灌引水．吸程高達5m．揚程達70m．出口壓力≥6bar。

2、流動寬敞，通過性能好．允許通過最大顆粒直徑達10mm。抽送泥漿、雜質時，對泵磨
損甚微；

3、揚程、流量可通過氣閥開度實現無級調節(氣壓調節在1—7bar之間)：

4、該泵無旋轉部件，沒有軸封，隔膜jl等抽送的介質與泵的運動部件、工件介質完全隔開，
所輸送的介質不會向外泄漏。所以抽送有毒、易發揮或腐蝕性介質時，不會造成環境污染和
危害人身安全；

5、不必用電．在易燃、易爆場所使用安全可靠；

6、可以浸沒在介質中工作：

7、使用方便、工作可靠、開停只需簡單地打開和關閉氣體閥門．即使由于意外情況而長時
間無介質運行或突然停機泵也不會因此而損壞．一旦超負荷，泵會自地動停機，具有自我保
護性能，當負荷恢復正常后，又能自動啟動運行；

8、結構簡單、易損件少，該泵結構簡單，安裝、維修方便，泵輸送的介質不會接觸到配氣
閥，聯桿等運動部件，不象其他類型的泵因轉子、活塞、齒輪、葉片等部件的磨損而使性能
逐步下降：

9、可輸送較粘的液體(粘度在1萬厘泊以下)：

10、本泵無須用油潤滑，即使空轉．對泵也無任何影響，這是該泵最大特點

 QBK is coosai's new developed series of AODD pump which is also the third generation, it has
the virtue of long service life and nonstop operation, not only it can convey some uneasy flowed
medium, with the merits the merits of self-pumping pump, diving pump, shield pump, slurry pump
and impurity pump etc.

 1. It's unnecessary to pour the drawing water, the suction lift reaches 5m height, the
delivery lift reaches 70m length and theexport pressure >~ 6bar.

 2. Wide flow and good performance. The diameter allowed to pass the max grain reaches
10mm. The damage is very less to the pump while exhausting the slurry and impurity.

 3. The delivery lift and flow can pass the pneumatic valve open to realize the step less
adjustment (the pneumatic pressure adjust-ment is between 1-Tbar).

 4. This pump has no rotary parts and no bearing seals. The diaphragm will completely
separate the exhausted medium and pump running parts, working medium. The conveyed medium
can't be leaked outside. Thus it will not cause the environmental pollution and human body safety
dangerous while exhausting the toxin and flammable or corrosive medium.

 5. No electricity. It's safe and reliable while using in the flammable and explore places.

 6. It can be soaked in medium.

 7. It's convenient to use and reliable to work. Only open or close the gas valve body while
starting or stopping. Even if no medium operation or pausing suddenly for long time because of
accident matters, the pump will not be damaged caused by this. Once over-loading, the pump will
automatically stop and possesses the self protection function. When the load recovers normally, it
also can start automatically.

 8. Simple structure and less wearing parts. This pump is simple in structure, installation
and maintenance. The medium conveyed by the pump will not touch the matched pneumatic valve
and coupling lever etc. Not like other kinds pumps, the performance will drop down gradually
because of the damages of rotor, gear and vane etc.

 9. It can transmit the adhesive liquid (the viscosity is below 10000 centipoises).

 10. This pump needn't the oil lubricant. Even if idling, it has any influence to the pump.
This is a characteristic of this pump.
