Plasric diaphragm pump-QBY4-10/15

Model Indentification: 

What is air operated diaphragm pumps?

QBY 4 is JK's new developed model diaphragm pump series which is also the 4 generation,it has the virtue of long life span and nonstop operation,not only it can convey some uneasy flowed medium,which the merits the merits of self priming pump,diving pump,shield pump,slurry pump and impurity pump ,etc.

1. It is unnecessary to pour the drawing water,the suction lift reaches 3m height ,the delivery lift reaches of 70m length and the export pressure 6 bar.

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 adjustment is between 1-7bar).

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

5. No electricity,it is safe and reliable while using in the flammable and explore places.

6. It can be soaked in medium.

7. It is convenient to use and reliable to work,Only open or close the gas valve body while staring 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 damaged of 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 no any influence to the pump,this is a characteristic of this pump.

Working principle and characteristics:

Diaphragm pump is a positive displacement pump that uses compressed air as its power and the volume changes caused by the reciprocating deformation of the diaphragm. Its working principle is similar to that of a plunger pump. Due to the characteristics of the working principle of the pneumatic diaphragm pump, the air operated diaphragm pump has the following characteristics:

(1) The pump will not overheat: compressed air is used as power, and it is a process of expansion and heat absorption during exhaust. The temperature of the pneumatic pump is reduced when it is working, and no harmful gas is discharged.

(2) No electric sparks: Pneumatic diaphragm pumps do not use electricity as power, and prevent static sparks after being grounded.

(3) Liquids containing particles can be passed: because the volumetric work and the inlet is a ball valve, it is not easy to be blocked.

(4) The shearing force to the material is extremely low: it is how to suck in and out when working, so the agitation to the material is minimal, which is suitable for the transportation of unstable materials.

(5) The flow can be adjusted, and a throttle valve can be installed at the material outlet to adjust the flow.

(6) It has the function of self-priming.

(7) It can run dry without danger.

(8) Can dive for work.

(9) The fluid that can be transported is extremely wide, from low viscosity to high viscosity, from corrosive to viscous.

(10) No complicated control system, no cables, fuses, etc.

(11) Small size, light weight and easy to move.

(12) There is no need for lubrication, so it is easy to maintain and will not pollute the working environment due to dripping.

(13) The pump can always maintain high efficiency and will not be reduced due to wear.

(14) 100% energy utilization, when the outlet is closed, the pump will automatically stop, there is no equipment movement, wear, overload, and heat.

(15) There is no dynamic seal, easy maintenance to avoid leakage, and no dead spots during work.
