The Peristaltic Dosing Pump is a critical component in SCADA-controlled water and wastewater treatment plants, designed for precise, reliable, and chemical-resistant pumping of liquids including chlorine, acids, caustics, and coagulants. These pumps operate using a rotating roller or shoe mechanism that compresses flexible tubing, creating a peristaltic motion that moves fluid. This design ensures chemical isolation, minimal contamination, accurate flow rates, and safe handling of aggressive or hazardous chemicals.
In modern water treatment SCADA systems, peristaltic dosing pumps provide precise chemical feed rates to achieve disinfection, pH adjustment, coagulation, flocculation, and nutrient control. The pump’s speed can be adjusted via analog input signals (4–20 mA), pulse control, or digital commands from PLCs or SCADA systems, enabling real-time process control. The SCADA interface allows operators to monitor pump speed, cumulative chemical volume, alarms, and fault conditions, ensuring safe and efficient operation. Peristaltic pumps are widely deployed in chlorination systems, acid/base dosing for pH control, polymer dosing for flocculation, and nutrient dosing in wastewater treatment. Their tubing-based design eliminates valves and seals, reducing maintenance, preventing leaks, and ensuring precise dosing over time. When integrated with SCADA, operators can schedule dosing based on flow-proportional control, water quality parameters, or batch treatment cycles. Historical data logged in SCADA enables process optimization, regulatory reporting, and predictive maintenance.
Modern peristaltic dosing pumps are designed for rugged industrial environments, with features such as chemical-resistant tubing, overload protection, integrated alarms, and corrosion-resistant housings. Many units also support remote monitoring, networked control, and automatic calibration routines, making them fully compatible with advanced water treatment automation. The combination of reliability, accuracy, and SCADA integration makes peristaltic dosing pumps essential for automated chemical treatment processes.
