Cast Steel Air Operated Diaphragm Pump Low Pressure 1 Inch Air Diaphragm Pump

Product Specification

Pneumatic Mining Low Pressure Diaphragm Pump With Butterfly Valves

Low Pressure Diaphragm Pump Description

 diaphragm pump offers high volume delivery even at low air pressure and a broad range of material compatibility options available.  pumps feature stall resistant design, modular air motor / fluid sections.

Air operated double diaphragm pumps utilize a pressure differential in the air chambers to alternately create suction and positive fluid pressure in the fluid chambers, ball checks insure a positive flow of fluid.

After ventilation, the pump stars to run, and the output pressure reaches the desired output. When the pressure in the output reaches the maximum limits(equivalent both of the inlet&outlet be closed) Pump will stop running. Once the pressure in the pipeline is less than the maximum valve the pump will resume operation..

Low Pressure Diaphragm Pump Parameters

Low Pressure Diaphragm Pump Main Advantages

1, Due to the use of air power, the flow automatically changed according to export resistance. Which is suitable for high viscosity fluid.
2, In inflammable and explosive environment, the pump is reliable and low cost, won't produce spark and not overheat,
3, The pump volume is small, easy to move, no foundation needed, convenient installation and economy. Can be used as mobile conveying pump.
4, Where there are dangers, corrosive materials processing, diaphragm pump can be separated completely with outside.
5, The pump shearing force is low, physical effect to medium is small, can be used for conveying unstable chemistry fluid.

AODD pumps can handle a wide range of corrosive, volatile, flammable, toxic fluids with particles and high viscosity.

1. Pump peanut butter, kimchi, mashed potatoes, small red sausage, jam apple pulp, chocolate, etc.
2. Pump paint, gum, pigments.
3. Adhesives and glue, all types can be pumped.
4. All kinds of tiles, porcelain, bricks and pottery glaze.
5. After the oil well is drilled, the sediment and grout are pumped.
6. Pump a variety of emulsifiers and fillers.
7. Pumping all kinds of age.
8. The pump is used as the tanker, and the barge clears the tank to absorb the age.
9. Hops and baking powder slurry, syrup, molasses.
10. Pumping water from mines, tunnels, tunnels, beneficiation, and slag.
11. Pumping cement grout and mortar, all kinds of rubber slurry.
12. Various abrasives, corrosives, oil and mud, cleaning grease and general containers.
13. A variety of highly toxic, flammable, volatile liquids.
14. A variety of strong acids, strong bases, strong corrosive liquids.
15. Various high temperature liquids can withstand up to 150 degrees.
16. As a pre-stage pressure supply device for various solid-liquid separation devices.

Troubleshooting guidance

1.Air outlet has fluid when pumping

 Check if the diaphragm be damaged

 Check if the diaphragm bolts loosening

2.The output fluid has bubble

  Check the suction pipe joints are well sealed

  Check the suction pipe and fluid inlet are well sealed

  Check the ring between fluid inlet and fluid cap are with O-ring

  Check the diaphragm bolts are fastened

3.Pumping capacity is low

  Check if the air supply is stable

   Check whether the inlet and outlet is blocked

   Check the joint to the fluid inlet is sealed and not leakage

   Check if the ball stick to the ball seat or ball seat is not suitable

4.  Without reciprocating motion, the air flow is discharged from the exhaust port

    Check the sealed ring of the main air valve

    Check the sealed ring of the pilot rod valve

    Check the sealed ring of the diaphragm rod
