What are metering pumps?

Metering pumps, also known as dosing pumps, are a positive displacement chemical dosing device. These pumps enable the dispensing of specific volumes of liquid either manually or automatically to other fluids streams or vessels through the expansion or contraction of chambers. Metering pumps can pump everything from corrosives, acids, bases, as well as viscous liquids and slurries.

These types of pumps can deliver fluids with a more than 3% accuracy across a wide range of discharge pressures.

Types of metering pumps

Although the most common type of metering pump includes diaphragm pumps, positive displacement pumps such as plunger pumps, peristaltic pumps and piston pumps, as well as different rotary pumps can serve as metering pumps.

Applications of metering pumps

Thanks to their ability to maintain constant flow of liquids regardless of pressure or fluid viscosity, metering pumps can be found in numerous industrial sectors, including:

• Manufacturing 
• Agriculture 
• Medicine 
• Pharmaceuticals
• Water & waste treatment 
• Food & beverage 
• Power generation
• Chemical processing 
• Oil & gas
