Gravi-Chek, the Motorless Water Pump, is the latest technology available in the ram pump industry. This pump is designed to pump water effectively uphill without a motor. The water itself, entering the pump at a ten percent grade provides the power and perpetual motion to activate this pump.
Carlson and Beauloye, in business since 1924, have crafted this Motorless Water Pump with durable new materials. The results are a powerful light weight aqua-dynamically designed pump that has revolutionized its industry.
Water must be clean or a filter or sedimentation tank at the connection is required. The fall to drive pipe relationship is 1-5 and can go up to 10' of fall/50' of drive pipe.
The shipping weight of the largest Gravi-Chek pump is less than fifty pounds, and can be shipped cost-effectively anywhere in the world by air freight.
