Why slurry pipelines?
environmental considerations
no noise
no dust
no smells
invisible mineral processing requirements
crushing and grinding at minesite
length of transportation
shorter routes
terrain conditions
mountains

Concept of large piston diameters and large stroke lengths - lower
stroke rates => lower wear High availability (98%) => suitable for continuous operation
Low stroke rates allow bigger valve sizes => lower slurry velocity in
valves => low wear => easy to maintain and lower spares
requirement
Very high efficiencies (up to 96%) due to roller bearings and
specially designed (low friction) piston seals => savings on power
requirement Variable operation range (10% - 100%)
Extensive after sales support through local representation world wide
