Blasthole Pumps 130SD - Model Specifications

Legra Engineering have introduced a range of Blasthole Dewatering Pumps that are self contained, and self propelled.

The big advantage is that these units are mounted on 3 x 8” pneumatic wheels, and hydraulically propelled, driving through the front wheel.  Direction controls, as well as steering, are easily operated from the tiller steering arm.  Travelling speed is a comfortable walking pace.

The hydraulic wheel motor will drive the unit over the roughest terrain and allow for accurate positioning of the wet end over the blast hole.  The unit has exceptional manoeuvrability, eliminating any damage to the Blasthole in tight patterns.  A tow hitch is fitted so that the unit can be hitched to a standard light vehicle, for transfer around the mine site.  Recommended maximum tow speed is 30 kph.  The unit will fit in most light vehicles, pick ups etc. should the pump need to be transported on a highway or public road.

The Self Drive range come standard with a 15HP (11.2kw) petrol motor driving a hydraulic pump.  This pump supplies hydraulic power to the water pump system, and the motion control motor, via manually operated control valves.  Pump entry/reclaim speed is 1m/s (3’/sec) via hydraulic motor and chain reduction.  A range of wet end sizes are available to give the size and performance to most applications.
