Compared to the Japanese manufacturer’s most powerful submersible motor pump model to date, the GPN 622, Tsurumi has been able to almost double the water output, to 9,000 litres per minute.
Classified as a ‘heavy sand pump’, the GPN 837 is suited for use wherever considerable amounts of solid matter are involved, for example in gravel pits or where sand, sludge, slurry and preferably also Bentonite are involved. As such, Tsurumi engineers have given the pump a solid construction. At 150 litres per second, hard rocks up to 30mm in size can pass through the pump with ease. The agitator at the suction opening mixes mud and water so that it becomes more fluid.
The near one-metre-high pump, which has a dry weight of 815kg, is driven by a 37kW electric motor. The GPN 837 pumps vertically up to 24 metres. When submerged, it is pressure-resistant to a depth of 30 metres.
Like everything else in Tsurumi’s product range, the GPN 837 is available from stock in Düsseldorf, Germany, or Antwerp, Belgium, and shipped to the customer within 24 hours. The model can also be rented for temporary work.
