Air operated double diaphragm pump Product description

 QBY air operated double diaphragm pumps not only can transfer the flow liquid, but also can transfer some uneasy flowed medium, with the merits of self-priming pump,diving pump, shield pump, slurry pump and impurity pump etc.

 1.It’s unnecessary to pour the drawing water, the suction lift reaches 7m height, the delivery lift reaches 70m length and the outlet pressure≥6kgf/cm²;

 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 exchausting the slurry and impurity.

 3.The delivery lift and flow can pass the pneumatic valve open to realize the stepless adjustment (the pneumatic pressure adjustment is between 1-7kgf/cm²) ;

 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 notcause the environment pollution and human body safety danger while exhausting the toxin and flammable or corrsive medium.

 5.No lectricity.It’s safe and reliable while using in the flammable and explore places.

 6.It can be soaked in medium to work.

 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 auotomatically stop and possesses the selfprotection function. When the load recovers normally, it also can start automatically.

 8.Simple structure and less wering parts. This pump is simple in structure, installation and maintance. The medium conveyed by the pump will not touch the matched pneumatic walve and coupling lever etc. Not like other kinds pumps, the performance will drop down.

 9.Gradually because of the damages of rotor, gear and vane etc.

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

Air operated double diaphragm pump Application

1.The pump can suck the peanut, pickles, tomato slurry, red sausage, chocolate, hops and syrup etc.

2.The pump can suck the paint,pigment,glue and adhesive etc.

3.The pump can suck various glazed slurries of tile, porcelain, brick and chinaware etc.

4.The pump can suck variousgrinding materials, corrosive agent and clean the oil dirt etc.

5.The pump can suck various toxin and flammable or volatility liquid etc.

6.The pump can suck various wedge water,cement sllurry and mortar etc.

7.The pump can suck various strong acid, alkali and corrosive liquid etc.

8.It can be used as a front-step  transmission device of the solid and liquid separation equipment.

Q:Raising goldfish can change water several times a day without an air pump Is that kind of common round shaped fish tank, because there is no air pump, afraid of goldfish hang up, please change the water a few days?
Look at the water quality, anyway, you change it every 3 days or so, do not change the light at one time.
Q:My cylinder is smaller.. It's probably only the size of the volleyball.. Two goldfish were kept.... A few days before the first floating phenomenon.. I bought an oxygen pump.. But I don't know whether to open it for 24 hours.. Do you have an oxygen pump?I want to ask you a question.. That's the fake flower I put in my tank.. But fake flowers make up a pretty large area of the fish bowl.. Does it have any effect on fish? It feels nice to put on and never let go.. Think the fish tank is empty
Better keep it open. If you are annoyed with electricity or noise, you can also stop and go. But to note that when the pressure is very low (such as cloudy, rain, wind, water and oxygen) is very powerful, never stop!
Q:What happens if the fish tank does not have oxygen in it and the fish tank is buzzing?Add ` have oxygen into, but the amount is very little, the sound is pure water of that machine, no water enter will ring, how to let him not sound ah?
The pump is blocked. Just clean it
Q:The difference between air pump motor 550W and 750W
This difference in power is the main difference in the performance of the air pump, which is different from the output of the gas under the condition of the gas pressure output. 750W is definitely higher than 550W.
Q:Keep a few fish, but the water is not clear, the change of water, add oxygen pump, and nitrifying bacteria can
May be the filtration system not perfect Oh, to a suitable collocation cylinder filter ~ can be Taobao search service our Kyrgyzstan and India we will contact the Jiyin professional for you collocation set for you perfect filtering system Oh
Q:What is the overheating of the printing press air pump?
What kind of model, if it is oil cooling, it may be the oil rotor is not good,
Q:Centrifugal fan can use as a pump? It can vacuum?
Also, the vacuum is not low, and barely scrape together. Mainly depends on your technical requirements.
Q:Does the heating machine have to use air pump?
Q:The pump stops and starts on its own. This happens several times a day
The general air pump itself will have an air bag, the pump will work into the air bag into the compressed air, when the pressure in the air bag reached a fixed value, will stop continuing to inflate, when the air pump will stop working. When the pressure of the package is not enough to support the use of the air pump, the pressure is automatically started. So it's normal to start and stop automatically.
Q:Why does the motor burn when the pump is powered on?
The pump motor when the power that is why hot? The current flowing through the coil, current thermal effect, the greater the load of thermal effect is larger, there is a pump stator iron core, coil current, electric current produces a magnetic field, the magnetization, the magnetization is alternating magnetization, will produce alternating magnetic reluctance will heat is generated, the core magnetization, core surface will produce eddy current, vortex core heat, the above reasons, so the pump casing made of aluminum fin type heat sink, the core heat dissipation into the air
