KSB Borehole Pumps – A Great Fit for the Oilsands Proven pumps ideal for recovery of brackish groundwater from deep deposits KSB’s UPA and UPZ families of borehole pumps are efficient, multi-stage specially designed to fit into a cylindrical space such as pipe or borehole.

(Photo KSB Pumps Inc.)They are available in diameters from 50 mm to 200 mm (2” to 8”) and can be supplied in a variety of corrosion-resistant materials – up to duplex stainless steel - which makes them suitable for handling aggressive fluids such as alkaline or brackish water. For abrasive conditions, the pumps can be fitted with silicon-carbide pump bearings and special wear rings. These pumps are available with capacities of up to 2,200 cubic metres/hour and heads as high as 1,400 metres. These pumps have proven to be very reliable and effective for water supply, mining and oil and gas operations, with over 300,000 installed worldwide.
These pumps have the potential of playing a very important role in the Alberta oilsands industry. Oilsands production requires large volumes of water and while improved technologies have reduced demand by increasing the amount of water that can be recycled within the process, some extra water – termed makeup water – is still required. Growing environmental concerns about the use of river water for oilsands production has accentuated the need for new sources of water, with deep underground wells as an especially promising alternative. The high salt content of this water means that it is unusable as drinking water but corrosion-resistant KSB borehole pumps are up to the challenge of recovering water from the deepest underground wells.
