Single Phase One Phase Pneumatic Diaphragm Pump QDM-902 Low Air Pressure
Introduction

Pneumatic diaphragm pump is a new type of conveying machinery. Its power supply is compressed air. It can take out various corrosive liquid with particles, liquid with high viscosity, volatile, poisonous. This pump is characterized by no need to irrigation water diversion for fire blast. It can pump flowing liquid and transport some free running dielectric, fire and explosion protection. Widely used in pharmaceutical, sewage treatment, food, chemical, automobile, paint and other industries.

Principle
Pneumatic diaphragm pump is the new kind of transportation machine, adopting compress air, smoke and industry exhaust gas as power source. It takes the air as momentum which compressed by air compressor. The needle valve adjust the air flow, which drive the membrane, then the pump transport the liquid.

Features

1. Because it is using air as power, the diaphragm pump does not heat and produce sparks; suitable for use in flammable and explosive environment.
2. Use Special material diaphragm, can be used for chemical properties relatively volatile liquid, corrosive medium.
3. Diaphragm Pump can pump particle liquid;
4. The liquid can be conveyed by diaphragm pump is wide, the viscosity from low to high, from corrosive liquid to viscous liquid.
5. Diaphragm Pump is small, light and easy to move.

Application

Used for coating, circulation, transmission of water-based ink printing machine, gravure printing, flexo printing and the ink on the compound machine, glue, and the liquid with particle, inflammable liquid.

Advantages

1. Firstly, the best choice for some diaphragm pumps with high pressure demand;

2. Free from rust and pollution, which greatly protects the cleanliness of medium. It is an excellent choice for some medical units, food processing enterprises and beverage industry.

3. It is doomed to be safe and quiet if it is powered by air.

4. Don't worry about the danger caused by wires and engines

5. Simple structure, convenient installation and maintenance, and the pump conveying medium will not touch the valve.

6. It can deliver relatively sticky liquid (the viscosity is below 10000 mm);

7. Easy to use, reliable to work, simply open and close the gas valve, and the pump will stop running automatically when the pipeline overpressure
