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.
