Introduction
Diaphragm metering pumps are precision metering devices that are used to accurately deliver a specific volume of liquid over a period of time. Generally utilized in a range of industrial processes, these compact pumps are renowned for their reliable nature, allowing for smooth and efficient operation under a variety of system conditions. In this article, we will take a more in-depth look at diaphragm metering pumps, highlighting the fundamentals of their design and exploring the inner mechanisms that support such stunning performance.
A Closer Look at Diaphragm Metering Pumps
Diaphragm metering pumps offer great flexibility, with their flow rate capabilities ranging from 0.2 to 1000 GPH (0.3 – 1500 LPH). The pump operation is relatively simple, as it relies on the basic principle of displacement. The diaphragm of the pump is pushed up and down by a pulsating power source, creating a suction on the suction side of the pump and a pressure on the discharge side. This motion displaces and forces out the exact amount of liquid that is necessary to complete the process.
How Does a Diaphragm Metering Pump Work?
Diaphragm metering pumps are powered by an electric motor that produces a rotary motion. This motion is then converted into a reciprocating action by a drive mechanism. The diaphragm is also connected to a movable armature that moves in a linear fashion. This action causes the diaphragm to move up and down, sucking in and pushing out the liquid. The displacement of the liquid is then regulated by a precision valve, which ensures that a consistent and predetermined flow rate is maintained.
Benefits of Diaphragm Metering Pumps
Diaphragm metering pumps are renowned for their accuracy, with many pumps boasting control accuracy of up to ±1 % of their maximum rated capacity. Apart from their superior metering performance, these pumps also provide several other advantages over other metering pumps.
· Corrosion-resistant materials for operation in hostile environments: Diaphragm metering pumps are made from a range of corrosion-resistant materials, making them ideal for use in harsh environment.
· Low shear forces: As diaphragm metering pumps use a reciprocating action, the pumping action is gentler compared to other types of metering pumps. This helps the product retain its original consistency and prevents damage to delicate components.
· Compact size and low noise levels: Compared to other types of metering pumps, diaphragm metering pumps are much smaller in size. This makes them ideal for applications with limited space.
Conclusion
Diaphragm metering pumps offer superior accuracy, reliability and performance. These pumps are ideal for demanding industrial applications, and their versatile design allows them to work in a range of operating conditions. Their compact size and low noise levels also make them ideal for situations where space is a priority. Ultimately, thanks to their reliability and precision, diaphragm metering pumps have become a top choice for many dedicated professionals.
Overall, diaphragm metering pumps are incredibly versatile and reliable devices that are used to accurately deliver a specific volume of a liquid in a set amount of time. Each of these pumps is driven by a rotary motion which is converted into a linear motion that then moves up and down. This motion causes pressure differences which force out the exact quantity of liquid needed for the process. Diaphragm metering pumps are known for their accuracy and are commonly used in industrial applications in which the liquid must retain its original consistency. Additionally, their compact size and low noise levels make them ideal for situations where space is at a premium. When utilized correctly, diaphragm metering pumps offer incredible reliability, accuracy, and performance.
