A case Study:

"How are we going to build this on-site?"

The contractor knew this pump control design would be a problem. The caustic metering system had to perform from 1 to 40 GPH with accuracy. Normally this would have taken weeks to install on site, with a difficult integration of the control panel and a lengthy calibration and startup procedure. Wastech Controls engineered a complete solution, fabricated it off-site, and delivered it on-time, pretested and ready to operate.

The unit included four DC drive metering pumps with local control panels, calibration columns, pulsation dampeners, pressure regulators, magnetic flow meters, and a NEMA-4X stainless steel remote control panel. The panel included SCR drives, RPM indication, stroke length indication, flow rate indication in GPM, HOA pump control switches, indicator status lights, communications, and numerous alarm conditions.
