High Pressure Air Driven Double Diaphragm Pump For Waste Water Treatment

Air Driven Double Diaphragm Pump Introduction

Air Driven Double Diaphragm Pump is a new type transferring machinery, is a newest pump at present in China. The power supply is adopt the air compression, to suck all kind of the corrosive liquid completely, such as liquid with granule, high-corrosive liquid, high viscosity, volatile, flammable, poisonous liquid.

Air Driven Double Diaphragm Pump Parameters

Air Driven Double Diaphragm Pump Advantages:

1. Explosion-proof, zero leak, simple operation.
2. Idling capability,Self suction, No complex control.
3. Diversity of material,no rotating parts,applicable to various erosive situations.
4. Diaphragm, ball and ball seat adopt imported materials with longer service life.
5. Modularization of main valve and air motor. No broken, easy to disassemble and repair

OPERATING INSTRUCTIONS

• Always flush the pump with a solvent compatible with the material being pumped if the material being pumped is subject to “setting up” when not in use for a period of time.

• Disconnect the air supply from the pump if it is to be inactive for a few hours.

• The outlet material volume is governed not only by the air supply but also by the material supply available at the inlet. The material supply tubing should not be too small or restrictive. Be sure not to use hose which might collapse.

• When the diaphragm pump is used in a forced -feed (flooded inlet) situation, it is recommended that a “Check Valve” be installed at the air inlet.

• Secure the diaphragm pump legs to a suitable surface to insure against damage by vibration.
