How to make full use of pneumatic diaphragm pumps

The pneumatic diaphragm pump is powered by compressed air. Sunpace centrifugal pump causes volume changes through reciprocating deformation of the diaphragm. Its working principle is similar to that of a plunger pump.

When operating a pneumatic diaphragm pump, please pay attention to the following points:

  1. Ensure that the largest particle contained in the fluid does not exceed the maximum safe passing particle diameter standard of the pump.
  2. The inlet pressure should not exceed the maximum allowable operating pressure of the pump. Compressed air higher than the rated pressure may cause personal injury and property loss and damage the performance of the pump.
  3. Ensure that the pump pressure pipeline system can withstand the highest output pressure achieved and ensure the cleanliness and normal working conditions of the drive air system.
  4. Static sparks may cause explosions, resulting in personal casualties and property losses. Use wires with a large enough cross-sectional area as needed to properly and reliably ground the grounding screw on the pump.
  5. Grounding requirements comply with local regulations, legal requirements and some special requirements on site.
  6. Fasten the pump and connecting pipe joints to prevent static sparks caused by vibration, impact and friction. Use antistatic hose.
  7. Periodically check and test the reliability of the grounding system, and the grounding resistance is required to be less than 100 ohms.
  8. Maintain good exhaust and ventilation, and keep away from flammable, explosive and heat sources.
  9. The exhaust of the pump may contain solid matter. Do not point the exhaust port of the Sunpace centrifugal pump toward the work area or people to avoid personal injury.
  10. When the diaphragm fails, the transported materials will be ejected from the exhaust muffler.
  11. When transporting flammable and toxic fluids, please connect the discharge outlet to a safe place away from the work area.
  12. Please use a pipe with an inner diameter of at least 3/8″ and a smooth inner wall to connect the exhaust port and the muffler.
  13. The high pressure of the fluid may cause serious personal injury and property damage. Please do not perform any maintenance work on the pump and Sunpace centrifugal pump pipe system when the pump is pressurized. If maintenance is required, cut off the pump inlet first. Air, open the bypass pressure relief mechanism to relieve pressure on the pipeline system, and slowly loosen the connected pipe joints.
  14. If the pump transports harmful and toxic fluids, please do not send the pump directly to the manufacturer for repair. Dispose of properly in accordance with local laws and regulations, and use genuine Sunpace accessories to ensure longevity.
  15. Pumps that use aluminum alloy materials for the liquid delivery part should not be used to deliver liquids containing Fe3+, halogenated hydrocarbons and other halogenated hydrocarbon solvents, otherwise corrosion will occur and the pump body will burst.
  16. Ensure that all parts in contact with the conveyor body will not be corroded and damaged by the conveyed fluid.
  17. Ensure that all operators are familiar with the operation and use of the pump and understand the precautions for safe use of the pump. If necessary, provide necessary protective equipment.
  18. Use the pump correctly and do not allow it to run dry for a long time.
