The WaterMax water cart was designed to improve product performance for fireproofing, stucco, and other bagged products by accurately delivering water to your specifications. Other water delivery methods used such as timers or mechanical meters are subject to user error and variability. This can mean loss of yield, bond strength, and time on a job site. The WaterMax water cart uses a digital flow sensor to accurately measure the water that has been dispensed and provide fast delivery combined with accurate dispensing. The WaterMax offers true measurement and control of water into your mixer.
