What are double diaphragm pumps?

Double diaphragm pumps are a type of positive displacement pump and they are widely used due to their versatility. These pumps operate using two flexible diaphragms that move back and forth to create suction and discharge. Driven by compressed air or electricity, double diaphragm pumps are known for their reliability, versatility, and ability to handle challenging applications.

Pump Selection – Key Considerations:

• Fluid Type – Is the fluid corrosive, abrasive, viscous, or shear-sensitive? These factors will all determine the materials of the pump required.
• Viscosity – The more viscous the fluid is, the more difficult it becomes to move. So, selecting the right pump is essential for reliable and consistent performance.
• Pressure – Checking the potential pressure conditions is also vital in pump selection, to ensure the pump can handle the required pressure.
• Chemical Compatibility – Knowing the chemical makeup of what you are pumping is essential when selecting a pump. You need to make sure the materials within the pump can handle the fluid being pumped.
• Temperature – The temperature that a fluid is being pumped at, will also determine what materials can be used in the build of the pump.
