Slurry Pump Tsurumi GPN422 is a submersible high power, heavy-duty slurry pump incorporating an agitator to suspend solids enabling the pump to handle high concentration slurries. Being equipped with high-chromium cast iron wear parts, the pump delivers outstanding durability. The suction plate is adjustable enabling the pump to maintain the original performance. The GPN utilizes a cooling water jacket to allow the pump to operate at low water levels for extended period of time without the fear of overheating.
Applications :
Submersible High Power Slurry Pump Tsurumi GPN422 widely used for :
- Transferring and draining bentonite slurry in piling works
- Draining cement slurry or sand-carrying water in foundation works
- Draining aggregate and or wash water in mines and quarries
- Collecting sediments in grit chambers at wastewater treatment plants
- Pump scale at steel mills
High-powered slurry pumps that deliver powerful agitation for discharging slurries laden with silt, earth, sand or other particulate. Submersible three-phase high power and extra heavy-duty slurry pump driven by a 4-pole or 6-pole motor. Equipped with a high-chromium cast iron agitator that assists smooth suction of the settled matters.
