What Is A Dosing Pump And How Does It Work?

A how-to tutorial for understanding what a dosing pump is and how it works. Risansi provides heavy-duty dosing pumps that are dependable in industrial applications.



What is a Dosing Pump?

Dosing pumps are oscillating positive displacement pumps that are designed to inject a wide range of media into a process at a precise flow rate. Dosing pumps, which are typically modest in size, give a highly precise flow rate for optimal control. They are the heart of an integrated dosing system developed for automatic chemical dispersion. This definition of dosing applies to a wide range of applications and industries, including wastewater treatment and food processing.

Where Are Dosing Pumps Used In?

  • Pumps are employed in industrial facilities, agriculture, manufacturing, medical laboratories, and mining activities, in addition to water purification and the food sector.
  • To neutralize the pH of a water storage tank, the pumps are frequently used to introduce a caustic chemical or an acid.
  • \In addition to dosing pumps, a chlorine pump is utilized to destroy bacteria. Certain variants are intended for extreme conditions such as high temperatures and high pressure.

How Does a Dosing Pump Work?

A dosing pump pulls a certain volume of liquid into its chamber and injects the chemical into a tank or pipe containing the fluid to be dosed. It is powered by an electric motor or an air actuator and contains a controller that controls the flow rate and turns the pump on and off. Some models have more advanced control systems.

Dosing Pump Types

These four types of dosing pumps are intended for a variety of pressures, substances, and uses. They differ in terms of pumping activity and mechanism.

Diaphragm (constant injection) pumps to fill and empty their chambers using a diaphragm, piston, and valves on both the input and output. Drawing in the piston fills the chamber, and a predetermined amount of chemicals is injected at a predetermined speed, which is usually a percentage of the maximum flow rate. Certain pump models may deliver variable dosage rates.

Diaphragm (pulse injection) pumps employ the same principle as diaphragm pumps, but instead of a constant flow rate, a solenoid coil takes up the chemical and injects it in pulses. The flow rate is defined as the period between pulses. It is less precise than the constant injection pump but is simple in design and inexpensive.

Lobe pumps allow a specific volume of fluid to pass via meshing gear impellors. It is not as precise as a diaphragm pump and is only appropriate for high-viscosity fluids that self-lubricate to reduce wear. They are not designed for low flow rates since precision is difficult to achieve.

Peristaltic pumps are particularly accurate for dosing. A flexible bent tube allows the fluid to pass through, and the flow is regulated by a roller on the exterior that moves via a mechanical arm. This forces the product in the tube into the dosing tube and the main fluid flow.

Risasni dosing pumps are an excellent choice for increasingly sophisticated dosages. These dosing pumps have redesigned driving and adjustment mechanisms. They offer very accurate, reliable, and lucrative processes, as well as the greatest possible price-performance ratio, through user-friendly operation and a clever Flow Control system.
