Coal-Face Pumps |
|
Self-Priming Single-Stage End-Suction
|
Designed as a portable mine drainage pump, used for local de-watering at the coal face, delivering chemically non-aggressive (seepage) water at pumping temperatures of max. 90°C into the intermediate or main draining system of mines as well as for disposal of neutral water from foundation pits on building sites and from mining excavations.
Skid mounted, electrically driven horizontal self-priming single-stage centrifugal pump with an overhung impeller (maximum 6m self-priming
lift).

Turbine Driven Single-Stage Glandless
|
Designed for evacuation of mine water in the coal and ore mining industry, for local water drainage during driving or sinking workings in the ore mining, for pumping accumulated water from excavations above ground while digging them as well as for de-watering of building foundations or excavations below ground level on building sites. Pumping temperatures up to 90°C.
A glandless combined pneumatic impulse turbine and single-stage vertical-shaft end-suction volute-casing centrifugal pump mounted on a common shaft. Single entry radial impeller. Water lubricated
bearings.
