QBY Pneumatic Diaphragm Pump
The machine combines the advantages of self-priming pumps and slurry pumps, especially suitable for high and low fluids. They contain no rotating parts, shaft seals or diaphragms, and moving parts and workpieces are completely separated from the medium. Our products have excellent leakage protection and can be used to convey toxic, volatile or corrosive media.
Suction: 5-7m
Head Lift: 0-50m
Max Air Pressure: 7kbf/cm 2
Product Description
Summarize:

QBY pneumatic diaphragm pump is one of the most innovative pump products at present, and is applicable for handling a variety of corrosive liquids, with particles, high viscosity, volatile, flammable, explosive, toxic liquids, tanker trucks and other liquids oil. Pump body overflow parts material using stainless steel, aluminum alloy, cast iron, diaphragm according to different liquid eye using butyl rubber, fluorine rubber, chloroprene rubber.
Product Details:
The two symmetrical working chambers of the diaphragm pump are each equipped with a piece of elastic diaphragm, and the two pieces of diaphragm are combined into one by connecting rod. Compressed air from the pump inlet connector into the valve chamber, push a working chamber of the diaphragm, and driven by the connecting rod connected to the diaphragm synchronized movement, while the other working chamber of the gas from the back of the diaphragm discharged. When the piston reaches the end of the stroke, the valve mechanism automatically introduces compressed air into the other working chamber and pushes the diaphragm pump to move in the opposite direction, thus forming a synchronized reciprocating motion of the two diaphragms. Each working chamber is equipped with two ball valves, the reciprocating motion of the diaphragm causes changes in the volume of the working chamber, forcing the two ball valves to open and close alternately, thus realizing the continuous suction and discharge of liquid.


 
Application:
1. The machines are used for the treatment of sewage and waste oil in drains and sewers.
2. Gas residue and acidic water at the bottom of refineries, which need to be centralized, our diaphragm pumps can be used to transport these waste liquids.
3. Our products can be used to pump glaze slurry in the ceramic industry.
4. In the petroleum refining process, oil often needs to be poured, loaded and sampled temporarily, in order not to contaminate the normal pipeline, diaphragm pumps can be a temporary substitute to get the job done quickly and easily.
5. This pneumatic diaphragm pump can be used to transport naphthenic acid, sodium sulfite liquid and benzene.
6. It can convey all kinds of highly toxic, flammable and volatile liquids, as well as
7. All kinds of strong acid, alkali and corrosive liquids.
Feature:
1. Large flow rate, good performance, allowing the maximum particle diameter of 10mm, when pumping mud, impurities on the pump damage is very small.
2. The head and flow rate can be steplessly adjusted by pneumatic valve opening (pneumatic pressure adjustment range is 1-7bar).
3. The diaphragm pump has no rotating parts, no bearing seals, the diaphragm will pumping medium and pump running parts, the working medium is completely separated, the conveying medium will not be leaked, so in the pumping of toxic, flammable, corrosive media will not cause environmental pollution and human safety hazards.
4. No electricity is needed, it is safe and reliable to use in flammable and explosive places.
5. It can be immersed in the medium.
6. Easy to use, reliable work, only need to open or close the gas valve when starting or stopping.
