Product Information

Full details

The VEVOR Air-Operated Double Diaphragm Pump is an ideal solution for industrial professionals and mechanics who need reliable liquid transfer of petroleum, diesel, oil, and other low-viscosity fluids. It delivers powerful, consistent flow rates and high-pressure capabilities for demanding environments, though it requires a constant compressed air source to operate, making it less suitable for portable applications lacking pneumatic equipment.

Extended Product Information

FAQs

Can this pump be used with water?

Yes, it is suitable for low-viscosity fluids, though it is optimized for petroleum, diesel, and oil.

Does this pump come with an air compressor?

No, this is a pneumatic pump and requires an external compressed air source to function.

What is the maximum pressure this unit can handle?

The maximum operating pressure is 80 PSI.

Is the body material resistant to chemicals?

Yes, the polypropylene body is designed for high chemical resistance in industrial environments.

How deep can the pump lift fluid?

It can prime up to 3 meters (10 ft) dry and 4.6 meters (15 ft) wet.

Is it safe to use with flammable fluids?

Yes, being air-operated, it does not produce electrical sparks, which is a major advantage for handling flammable liquids.

Troubleshooting

Pump fails to prime

Check all inlet connections for air leaks and ensure the suction hose is fully submerged.

Flow rate is significantly lower than rated

Verify that the air pressure is sufficient and check the inlet/outlet for potential internal blockages.

Air leaking from the exhaust

This may indicate a ruptured diaphragm; inspect the internal PTFE components and replace if worn or torn.

Pros and Cons

Pros

  • Corrosion-resistant polypropylene body
  • Reliable double diaphragm design
  • Strong self-priming capabilities
  • Handles various petroleum-based fluids
  • Impressive maximum lift height

Cons

  • Requires external compressed air supply
  • Not suitable for high-viscosity liquids
  • Heavy-duty design makes it less portable

Setup, Compatibility & Care

To set up the pump, connect a standard 1/2-inch hose to the inlet and outlet ports, ensuring all connections are sealed properly with industrial-grade sealant to prevent leaks. Connect your air compressor line to the pump's air intake, adjusting the regulator to stay within the 80 PSI maximum pressure limit. For maintenance, regularly inspect the intake and discharge valves for debris that might impede flow. Periodically drain the air line to prevent moisture buildup within the pump housing. Store the pump in a dry, protected area if it will be inactive for extended periods.
