What is the primary use of rotary pumps in water systems?

The primary use of rotary pumps in water systems is to effectively dispense treatment chemicals. These pumps are designed to handle the specific viscosities and flow rates required to deliver various chemical solutions, such as coagulants, disinfectants, and other additives that are essential in water treatment processes. Rotary pumps provide a consistent and controllable flow, which is crucial for accurately dosing chemicals to ensure the safety and quality of the water being treated.

In water treatment facilities, precision in chemical dispensing is vital to achieve desired treatment outcomes, such as optimal disinfection, pH adjustment, or coagulation for sedimentation. The design of rotary pumps, including their ability to maintain a steady pressure and flow rate, makes them particularly suited for this task. Additionally, their capacity to handle different chemical compositions without degradation allows for efficient operation over extended periods.

While rotary pumps can be versatile and may have applications in other areas, their primary role in water systems is indeed aimed at chemical dispensing rather than pumping water in large volumes, transporting sewage, or regulating pressure.
