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 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
