This small-diameter blast hole dewatering system is hydraulically operated and allows dewatering of 2.5 inch or larger holes to a maximum depth of 125 feet. The design of this unit allows for single-person operation. The operator lowers the head through the hole guard to the bottom of the hole. Using the winch on the hole guard, the operator is able to position the head off the bottom hole thus keeping the head from sucking itself into the muck. The pump then dewaters the hole, shuts the head off and signals the operator to move to the next borehole.

One hundred feet of tri-hose allows dewatering of several holes before the power unit needs to be moved. This unit is designed for maximum reliability and will pump abrasives suspended in liquids. The head has no water valves or water seals to leak or plug.
