The Challenge

A water treatment plant in the US state of Georgia uses several wells to provide its residents and industries with fresh water. Each well site had to be equipped with the appropriate treatment equipment to ensure that the water meets and exceeds regulatory requirements.

One such well site used a diaphragm-style reciprocating metering pump to pump lime slurry directly into the well output. The well runs about 12 hours per day and discharges either to the system or to the tower for storage. Lime slurry demand is up to 11.4 litres per minute (3 gallons per minute) and must be pumped at pressures exceeding 4 bar (60 psi).
