A dosing pump, also known as a dispensing pump, is a specific type of pump used to accurately dose precise amounts of liquids or pastes. These are commonly used in various industrial processes for repeatable addition of chemicals, additives, and more. Let's explore the key types of dosing pumps and their applications.

Peristaltic Pumps

Peristaltic pumps, also called hose pumps, work on the principle of mechanically compressing an elastic tubing or hose to propel the media inside it. As there is no direct contact between the pump mechanics and the fluid, food-grade dosing pump models are ideal for dosing in the food & beverage industries. Their self-priming function and ability to handle shear-sensitive or jam-prone products also make them applicable in dispensing glue, paints, and more.

Diaphragm Pumps

Diaphragm dosing pumps feature a flexible diaphragm that pushes the media via inlet & outlet check valves. These are suitable for the precision feeding of chemicals, alkalis, and acids across industries like water treatment, oil & gas, and mining. Their compact design with modular wetted parts simplifies maintenance in dosing applications involving corrosive or abrasive media.

Progressive Cavity Pumps

A food grade dosing pump provides an excellent non-pulsating dosing solution. Their shear-free pumping mechanism handles viscous fluids gently without compromising accuracy. Applications include adding flavors, colors, and preservatives in food processing as well as dosing polymers and latexes in various industries.

Applications in Various Industries

Food & Beverage:

Dosing sauces, syrups, flavors, thickeners, etc. onto production lines. Metering preservatives into packaged goods.

Chemical:

Feeding alkalis, acids, and other chemicals into processes. Dosing polymers and additives.

Pharmaceutical:

Accurately dosing active drug ingredients, binders, and excipients into formulations.

Water Treatment:

Adding disinfectants, flocculants, and other chemicals into purification processes.
