How to select AODD pumps

When selecting an AODD pump there are a few things to be considered regarding its suitability for application:

  • Fluid: The type and composition of the fluid you plan to pump is the most crucial factor. In order to avoid wear and tear or corrosion, determine the fluid’s chemical makeup and consistency, and whether it may be a clean or slurry liquid.
  • Viscosity: How viscous a fluid is can be a key factor into the pump selection process. Robust pumping equipment is needed to move highly viscous fluids.
  • Pressure: Determining the potential pressure conditions on the inlet and outlet of the pump.
  • Temperature: The temperature of the fluid dictates the pump material best suited to a particular application. We offer a wide range of clamped or unclamped plastic and metal Wilden & Almatec AODD pumps enabling you to select the pump best suited to your application.


  Our Wilden & Almatec pumps are also suitable for those operating with flamable fluids and are both CE & ATEX certified.  

For those operating with Corrosive and Abrasive fluids our Wilden & Almatec AODD pumps also have the option to use PTFE diaphragms
