Everything You Need To Know About Electric Diaphragm Pumps

Much like any other pump, diaphragm pumps are used to transport liquids. However, in some instances, other pumps cannot move what is needed. On the other hand, diaphragm pumps can move all types of liquid and are usually made from various materials to match all applications.

Although diaphragm pumps mainly transport liquid, they may also pump solids when necessary. This makes diaphragm pumps an ideal option for transporting liquids with high-solid contents. There are different types of diaphragm pumps available for industry use, but the most common are electric diaphragm pumps.

Defining an electric diaphragm pump

Before defining what an electric diaphragm pump is, it is important to understand what diaphragm pumps are in general. A diaphragm pump is basically a pump that operates under the positive displacement mechanism and functions with fused check valves and an adjustable diaphragm. This diaphragm is shifted in and out toward the body of the pump, which operates together with the check valves and pulls in and releases the fluid out of the pump casting. 

An electric diaphragm pump is a type of diaphragm pump that is mechanically driven in contrast to its air-operated counterpart. It is a double diaphragm pump that comes with an electric drive motor attached. This electric drive stimulates the pumping action rather than the air or fluid used in pneumatic or hydraulic pumps. Compared to air-operated diaphragm pumps, electric diaphragm pumps are said to be more efficient.

Understanding how an electric diaphragm pump works 

An electric diaphragm pump usually comes with a roller system and a cam built into its centre section, which generates a linear back-and-forth motion. This centre section likewise has an air pressure charge that assists in the production of the left or right motion. Here, the liquid is pushed into one chamber through the inlet manifold and forced out of the other chamber through the outlet manifold.

When this changeover occurs, the chamber that was filled during the prior shift clears into the outlet manifold and the other chamber is then filled through the inlet manifold. The seamless changeover enables pulsation at the pump’s outlet to be greatly minimised in comparison to air-powered units. An electric diaphragm pump usually has a pressure range of at least 60 to 100 psi.

Benefits of an electric diaphragm pump

• Self-Priming

Electric diaphragm pumps are intended to be self-priming. This means that they come with fluid inside that helps reduce air pockets and boost operational efficiency.

• Energy-Efficient

Electric diaphragm pumps are generally high-efficiency pumps. They are more energy-efficient compared to air-operated alternatives by up to 80%. This makes them far less costly to operate. 

• Versatile

Electric diaphragm pumps are designed in such a way as to make them ideal for use with corrosive, volatile, or viscous fluids. Because of their fluid pumping procedure, these pumps are also able to handle materials with little solids.

• Able to Stall Under Pressure

Once fluid pressure goes beyond the charged air pressure in the pump’s centre, the diaphragm then locks in. This helps avoid pump failures from closed valves or clogged lines.

Conclusion 

Electric diaphragm pumps are called such because they are attached to a motor that operates the shaft to move the diaphragm back and forth, thereby resulting in greater efficiency. Electric diaphragm pumps come with a variety of benefits that make them ideal for industry use. However, in order to experience the maximum advantages of an electric diaphragm pump, be sure to purchase your equipment only from a reliable pump supplier in Pioneer in Singapore.
