ARO INGERSOLL RAND started its business in 1930, began selling pneumatic diaphragm pumps in the 1950s, and was acquired by Ingersoll-Rand in 1990. Now belongs to the fluid transport division, providing high quality products and services. ARO Ingersoll Rand Diaphragm pumps have valve corrosion resistant accessories, and other design advantages. The ARO pneumatic diaphragm pump has the advantages of no overtemperature, no power loss, can deal with suspended matter and can easily adjust the transmission. ARO DIAPHRAGM PUMP CAN TRANSPORT VARIOUS VISCOSITY LIQUID, suitable for various industries of feeding, such as painting, sewage, waste disposal, etc.

Pneumatic diaphragm pump: pump body material of stainless steel, aluminum alloy, cast iron, PP; The diaphragm material is teflon and general rubber; Caliber 1/4 inch to 3 inches; Flow range 17 increased to 1040 liters. The principle of large flow, ARO Ingersoll Rand pneumatic diaphragm pump: ARO diaphragm pump operation is very simple can be self-suction, can adjust the air pressure and fluid back pressure can meet the needs of various flow, can deal with wear is very strong or sensitive boring and meet the needs of different industries. Pneumatic diaphragm pump is used in fluid transport and spraying industry, paint, chemical, beverage, food, printing, pharmaceutical, textile, construction and other applications in different industries.

This is manifested in the following aspects:

1. Suitable for precious liquid, high harm, high corrosive and other dangerous materials transportation, ARO Engsoll pneumatic diaphragm pump no dynamic seal structure, completely separated from the outside world, no leakage;

2. It is suitable for the transportation of all kinds of fluids in flammable and explosive environment, because ARO Ingersoll Rand pneumatic diaphragm pump does not generate electric spark and heat in the work

3. Suitable for harsh working conditions such as oil fields, mines, construction sites containing solid particles of wastewater, no blockage, no overload, no leakage.

4. It is suitable for conveying all kinds of materials in light and mobile occasions, without foundation, small footprint, flexible, easy to install and economical;

5. It is suitable FOR CONVEYING ALL KINDS of acid, alkali and corrosive fluids and solvents with high, medium and low viscosity in chemical industry. Because the compressed air is used as the power, the flow automatically adjusts with the change of back pressure, the working point range is wide, and the working point is automatically set.

6. It is suitable for conveying high purity and clean materials, because ARO Ingersoll Rand pneumatic diaphragm pump does not need lubrication, no lubricant pollution of materials. Such as in pharmaceutical intermediates and products, laboratory pharmaceutical delivery;

7. It is suitable for conveying fluid with unstable chemical properties because ARO Ingersoll Rand pneumatic diaphragm pump has very low shear force on materials.
