Water pump

fuelairdiesel

The YONJOU underground mining dewatering pump with semi-open impeller and a simplex separator where air can separate from the liquid and be sucked by a vacuum pump. The vacuum pump allows the unit to be primed automatically and capable of drawing significant quantities of air, allowing the priming of a wellpoint system and maintaining it under vacuum, or draining an excavation thoroughly under “snore” conditions. Our dry prime vacuum assist dewatering pump series integrates our unique vacuum system with high performance centrifugal pumps for maximum performance in air handling and water volume. The water ring vacuum system used in our wellpoint pumps is independent of the centrifugal pump, with no cross contamination to wear on vacuum pump tolerances. Available in sizes from 4” to 10”, diesel or electric powered. The vac assist pump is also called: Dry prime pump or dry prime dewatering pump Vacuum assisted centrifugal pump High flow fuel pump or vac assist high flow diesel pump Automatic self priming pump or dry self priming pump Vacuum assisted pump or vacuum assist pump Vacuum prime assist trash pump
