Double diaphragm pumps from the PRO series
Ideal for general industrial and OEM installation applications
The compressed air-driven diaphragm pumps from the PRO series are ideal for general industrial and OEM installation applications. The double diaphragm pumps deliver a high pump output of up to 897 l/min for products ranging from clean, low-viscosity liquids to corrosive, abrasive, medium-viscosity liquids and can pump large particles without any damage.
Most ARO® diaphragm pumps are also ATEX-certified (CE Ex11 2GD X).
Advantages of double diaphragm pumps from the PRO series:
- Seal-free construction
- Low material wear translates into high reliability
- Rapid maintenance and repairs thanks to easy access to ball retaining valves and liquid covers
- Multiple connection options provide flexibility for the intended use
- Can be run dry without incurring any damage
- Mobile use
- Self-priming
- Simple installation
- Available for use in hazard zones (ATEX, NEC and CEC certifications)
