Understanding the Efficiency of Air Diaphragm Pumps

An Air Diaphragm Pump, also referred to as a Membrane pump, is a unique type of positive displacement pump. It operates based on the combined reciprocating action of a rubber, thermoplastic or teflon diaphragm, alongside suitable valves on either side of the diaphragm. This unique construction can be explored in more detail on the Air Diaphragm Pump page.

The Functionality of Double Diaphragm Pumps

A double diaphragm is a specific type of positive displacement pump. It functions by utilising two adaptable diaphragms that reciprocate back and forth. This motion creates a temporary chamber, which both draws in and expels liquid through the pump. The two diaphragms are linked by a shaft through the center section where the air is located.

Self-Priming Capabilities of Positive Displacement Pumps

Although it depends on the pump and its application, a positive displacement pump is typically a self-priming pump. For instance, air operated diaphragm pumps self-prime by creating a pressure differential in the diaphragm chamber. This action draws in air and pulls the fluid into the suction port.

Common Questions About Air Diaphragm Pumps

1. What is the purpose of a diaphragm in these pumps?

The diaphragm in an Air Diaphragm Pump is responsible for creating suction and discharge strokes, allowing the pump to move fluid.

2. Are these pumps self-priming?

Yes, most positive displacement pumps, including Air Diaphragm Pumps, are self-priming. They create a pressure differential in the diaphragm chamber, drawing in air and pulling fluid into the suction port.
