In many sectors such as automotive, chemistry, metallurgy, printing, pharmaceuticals or water treatment and wastewater treatment, accuracy and repeatability of processes are fundamental. These domains involve numerous dosing applications. Therefore, industrial dosing pumps play a crucial role.
Dosatron dosing pumps differ from standard dosing pumps in two major aspects (check our specific page How does a dosing pump work?):
As a direct consequence of their specificities, they possess three major advantages:
The function of an industrial dosing pump is to transfer or inject a defined volume of additive or liquid within a specified time frame. In most cases, the amount of liquid to be injected is related to the flow rate of a fluid in which it must be incorporated. Usually, the specifications are expressed in terms of injection flow rate and injection pressure.
The industrial dosing pump operates on the principle of a positive displacement pump. The transfer of chemicals is achieved through an injection head that, through a reciprocating motion, draws in and delivers a defined volume. In general, injection heads incorporate technologies such as "piston" or "membrane". The volume transferred is then related to the pump head type and stroke length. These technologies enable accurate injection of a specific quantity of liquid through each operating cycle, ensuring a constant flow rate and excellent repeatability.
As the chemical transfer is controlled based on the flow rate of a fluid to be treated, it results in accurate dosing of the additive into the fluid (e.g., dosing of soluble oil to lubricate and cool down the tool/workpiece interface during machining).
Since their introduction on the market, industrial dosing pumps have undergone numerous improvements and innovations to enhance their performance and provide value to their users. However, we can distinguish the following main families:
These pumps can also differ in their drive systems:
