ESP A51 Mk IIB
Electric Swellex®pump ESP A51 Mk IIB isa fast and quiet, high pressure water pump. Ithas an electrically driven axial 5-plunger pumpfor up to 300 bar installation pressure. The mainadvantage is that the flow delivered by thepump, is independent of the water pressure,and is thus speeding up the bolt expansionprocess. The expansion time for a 6.0 m longSuper Swellex rockbolt is less than 60 seconds.The pump is equipped with an electric mainswitch, which features an LED display, and apressure sensor on the incoming water side.The outlet pressure can be adjusted to matcheither Swellex bolt type.
