ARO 2" EVO Series Metallic Electric Diaphragm Pump

Available in three materials: aluminum, stainless steel, and cast iron.

The aluminum version is the most cost-effective option, while the stainless steel and cast iron versions offer greater durability and corrosion resistance.

Product Description

Features
  • The pump features a unique 3-chamber design that significantly reduces pulsations without the need for additional dampener accessories. The compact footprint fits into small operational spaces, and installation is easy, with no need for a base plate or shaft alignment.
  • The EVO Series pump also features a number of safety features, including real deadhead protection and built-in leak detection. Real deadhead protection ensures that the pump will not overheat or be damaged if the flow is stopped. Built-in leak detection sensors can detect diaphragm failure and shut down the pump to avoid leaks.
  • Real Deadhead Protection: An encoder senses the speed and will slow the motor down and hold the programmed system pressure for long periods of time. The automated system enables the pump to restart the process without priming or can be programmed for automatic shutdown.
  • You can monitor and control the pump flow according to changing process parameters like flow, head, torque and others.
  • The EVO Series™ innovative design can save more than 20% on energy costs compared with competitive models and technologies
