Metering pumps are designed to deliver precise volumes of fluid at accurate flow rates. These pumps use components like diaphragms or pistons. These components are integral to the operation of metering pumps. Their operation consists of displacing a fixed volume of fluid with each stroke.
The metering pumps have a reputation for offering high precision. This allows accurate dosing of chemicals and other fluids. They are versatile and capable of handling a wide range of fluids. The metering pumps can even handle aggressive chemicals and viscous materials.
Metering pumps offer features like adjustable flow rates. This ensures precise control over fluid delivery. They are essential in various industries where precise dosing is critical. These include:
- Water treatment
- Chemical processing
- Food and beverage
- Pharmaceuticals
- Agriculture

The Journey of Metering Pump Technologies Since Inception
The journey of metering pumps began in the 1930s. That was the time of manually operated plunger pumps. These plunger pumps were prone to leaks, which was a prevalent problem for a long time. It was in the 1950s when the industry witnessed significant improvements with the advent of hydraulic diaphragm pumps. The separation of the piston from the fluid was an innovation that significantly improved and enhanced the accuracy and reliability of these metering pumps. In the 1970s came the solenoid-driven pumps. These had fewer moving parts. They paved the way for electronic control and automation.
Since then, the metering pumps have seen continuous advancements, some of which are:
- use of advanced materials like PTFE and PVDF
- improved motor designs
- integration of digital flow meters and controllers
Today, we have smart metering pumps that come with IoT capabilities. These smart pumps allow for remote monitoring and optimisation. These advancements have enhanced performance and efficiency. They have ensured compliance with stringent environmental and safety regulations.
The journey of these metering pumps reflects the advancements in fluid handling technology. They have ensured that metering pumps remain indispensable tools in modern industries.
