Metropolitan Industries’ System 2100 is a water-pressure booster system ideal for medium- to high-pressure applications. When demand increased, the system adjusts to meet it, the company notes. Smart pump technology incorporates a zero-flow shutdown feature, which saves money and increases the life of pump systems, Metropolitan adds. Metropolitan’s Metro-Tech III controller allows operators to set pump operations, and displays information on its inter-face. This controller maintains a constant discharge pressure by varying the speed of the water-pressure booster pumps while maintaining system flow requirements. The control saves energy, reduces water hammer and provides accurate setpoint control, even under the most demanding conditions, Metropolitan says. Metropolitan Industries. www.metropolitanind.com
