New metering pump
The new 520Du peristaltic pump will be introduced at AWWA 2004, June 13-17 at the Orange County Convention Center in Orlando, FL. Designed to handle the most corrosive fluids with reliable and accurate metering performance, the unit is ideal for chemical metering applications such as sodium hypochlorite. Unlike diaphragm metering pumps, the unit will never vapor lock due to the off gassing of the hypochlorite. In addition, ancillary equipment such as back pressure valves, strainers and pulsation dampeners are not required.
