Before we start this article, it is essential to understand that electric diaphragm pumps play a vital role in several important industries, such as paints, dyes, ceramics and slurry. So, electric diaphragm pumps are basically positive displacement pumps that operate using reciprocating diaphragms powered by an electric motor rather than compressed air-like air-operated diaphragm pumps. The electric motor enables the diaphragm to oscillate, creating a vacuum that draws fluid in and then consistently pushes it out. Robust mechanism with hassle-free maintenance, making these pumps ideal for various applications.
The use of electricity in electric diaphragm pumps, commonly referred to as sealless process pumps, significantly contributes to substantial savings for operators. By relying on electrical power instead of other energy sources, these pumps can reduce operating costs and energy consumption by as much as 80%, offering both economic and environmental benefits in the long run.
Electric diaphragm pumps are versatile devices capable of transferring liquids with varying viscosities—ranging from low to high—and can even handle fluids containing suspended solids. Owing to their wide selection of materials available for the pump body (including but not limited to polypropylene, stainless steel, and aluminium) and diaphragms (such as Santoprene and PTFE), these pumps are also widely used for managing aggressive chemicals, including acids.
The workings of electric diaphragm pumps
But how exactly does an electric double diaphragm pump work?
Electric diaphragm pumps work through a series of small and big well-coordinated actions that ensure the precise transfer of fluids the operator requires. It all starts with the suction stroke, where the diaphragm, driven by an electric motor, moves away from the pump chamber. This movement results in a low-pressure zone within the chamber, drawing fluid into the pump through an inlet valve. The inlet valve, typically a ball check valve, allows the fluid to get into the chamber while ensuring no backflow. As the diaphragm’s movement is repeated a few times, the chamber gradually fills with liquid, all set for the next phase of the pumping cycle.
In the next stage, the diaphragm returns to its original position in the discharge stroke, compressing the fluid within the chamber. The result is an increased internal pressure which forces the fluid out of the chamber through a discharge valve. The discharge valve has been designed to ensure the fluid leaves the pump in a controlled, one-way flow, moving into the outlet or discharge pipe. It is important to note that the electric motor is the heart of this operation; it converts electrical energy into mechanical force, eventually enabling a linear mechanism. This mechanism converts the motor’s rotary motion into a kind of back-and-forth movement that gives energy to the diaphragm. The pump chamber – where the liquid is contained during the cycle – on the other hand, works in perfect harmony with strategically placed check valves, ensuring efficient fluid transfer and preventing any reverse flow.
But why should one consider buying electric diaphragm pumps?
But why should one research the workings of electric diaphragm pumps, go through several quotations and decide to buy these pumps? Well, there are several reasons to convince a consumer. For starters, these pumps are very energy efficient. They minimise energy consumption by almost five times compared to an AODD pump. The second reason to consider electric diaphragm pumps is their flexibility. These pumps allow the operator to control and adjust the speed and flow rate, resulting in optimum product usage. These pumps can be assembled and disassembled with ease, and the repair, for the most part, is simple and cheap. And there is one more thing – these pumps are easy on the ears! Owing to its electric motor, electrically operated double diaphragms are able to operate with minimum noise.
