New Chemical Metering Systems

Watson-Marlow introduces its new Chemical metering Systems, designed for easy operation and low maintenance metering of tough water purification chemicals like sodium hypochlorite and ferric chloride. They are ARRA compliant and also very easy to install.

Using peristaltic pumping, the system delivers metering accuracy of +/- 1% and far better reliability than diaphragm pump systems. There are no back pressure regulators or de-gassing valves required and maintenance is a simple one-minute tube change.

Watson-Marlow Chemical Metering Systems provide customers a turnkey wall or floor mounted solution for precision metering - including the pumps, valves, pressure relief, gauges, calibration column, leak detection and all interface pipework. The system can be directly tied into customer SCADA systems via analog, digital, or PROFIBUS control. These systems are ideal for chemical injection up to 100 psi, can run dry indefinitely without damage and provide up to a 30' suction lift.
