  Mining Drilling Rigs - Pole Drilling
The PRD HFU is rugged and powerful with its hydraulically driven pump and its 12,000 lbs. Mast, the PRD HFU is sure to get the job done. This two speed unit provides dual functions, break and develop. In low speed the pump will produce 2500 psi at 40 gpm. This is essentially your break pressure. In high speed it produces 500 psi. At 80 gpm, this develops the well allowing for optimal water flow.
