QDM-902 Pneumatic Diaphragm Pump For Mix Ink Safe Aired QDM-902 Single Phase
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.

Principle
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.

The scope of application
Printing industry

Chemical industry producing printing ink(water-based, oily) solvent, ethanol, tuluol, acetone, dope and so on

Other industry need the safe pneumatic pump.

Characteristic
1. Low air consumption, the medium flow regulation is stepless regulation, and it is adjusted by air inlet valve.
2. Membrane is made of corrosion resistant material, so it can be used to transport corrosive medium.
3. Low failure rate, easy to install, convenient maintenance.
4. The pump shell is made of high quality material, the inner parts are made of stainless steel and copper, all of those make the pump light, beautiful, stainless and anticorrosive.
