Motorised Vacuum Dewatering Pump is widely used for the mixing method for having high quality long strip casting of floors. The Vacuum Dewatering Pump removes the excess water from the green concrete by vacuum process enabling the water-cement ratio to reduce drastically. The Vacuum Dewatering Pump is designed in a way such that the wet concrete is compressed by atmospheric pressure and the excess water is squeezed out of the Pump. The Motorised Vacuum Dewatering Pump brings compactness to the concrete and improves the compressive strength, density and the resistance to water penetration.
