Dosing Pumps and Their Role in Precision Applications
Dosing pumps are part of the positive displacement pump family, which includes eccentric screw pumps, lobe pumps, diaphragm pumps, peristaltic pumps, and others.
The technology utilised in dosing pumps varies significantly based on the application requirements. For instance, in applications such as water distribution, chemical processing, and pharmaceutical manufacturing, where precise dosing is very important, diaphragm pumps are often the preferred choice.
They offer exceptional accuracy and reliability in delivering exact quantities of fluid, making them ideal for such demanding environments.
By leveraging the appropriate dosing pump technology, it is possible to achieve highly accurate and consistent fluid delivery, ensuring optimal performance and compliance with stringent industry standards.
Discover the Various Dosing Pump Technologies
In this section we will introduce you to the 4 main dosing pump technologies
Diaphragm Dosing Pumps
This is probably the most commun, but also the most accurate technique. It is used for many applications from water distribution to chemical processes and more.
There are various types of diaphragm pumps, from the most accurate dosing to the more commun AODD types (Air Operated Double Diaphragm Pumps) that offer a reasonably constant flow where the accuracy is less critical.
Eccentric Screw Dosing Pumps
Eccentric screw pumps are positive displacement pumps. As such their flow is exactly related to the rotating speed of the shaft.
Eccentric srew pumps for dosing are ideal for applications requiring higher flow rates. They are often used for dosing polymers in water treatment processes.
Peristaltic Dosing Pumps
One of the main benefit of peristaltic pumps is that the fluid never comes in contact with the pump parts, making it an ideal choice for specific applications i.e. in the food industry and more.
Lobe pumps
Lobe pumps, which are positive-displacement pumps suitable for viscous and charged fluids, come in two main types: those with rubber lobes (straight or helical) and those with steel lobes (straight or helical). Steel, which is harder, offers greater resistance to wear and higher pressures than rubber.
In general, lobe pumps offer flow rates of up to several hundred cubic metres per hour and pressures of up to 20 bar, or even more for certain steel models.
Gear Pumps
Gear pumps are positive displacement pumps that use intermeshing gears to move fluids with high precision and efficiency. They are commonly used in applications requiring consistent flow rates and handling of viscous fluids such as lubricants, chemicals and hydraulic oils. Their robust design ensures reliability and minimal maintenance, making them ideal for industrial processes that demand durability and consistent performance.
