The GPN-series is a submersible three-phase high power and extra heavy-duty slurry pump driven by a 4-pole or 6-pole motor. It is equipped with a high-chromium cast iron agitator that mixes settled matter into suspension for pumping. The other wear parts such as the impeller and the suction plate are also made of high-chromium cast iron for extra durability. The side discharge, spiral design allows smoother passage of the sucked solid matters. The motor is cooled by a water jacket that assures efficient motor cooling even when it operates with its motor exposed to air. The use of guide rail fitting system improves convenience in the facilities such as, iron works, ready-mixed concrete plants, and wastewater treatment plants where the pump is to be installed with a fixed discharge piping.

Slurry Wall Applications

Slurry walls are used in various construction and engineering applications where the creation of a deep, watertight, and structurally stable barrier is necessary, for example in tunnel construction to stabilize the surrounding soil and prevent water ingress during tunnel excavation.

Slurry walls are typically constructed by starting with a set of guide walls, typically 1 metre (3 ft 3 in) deep and 0.5 metres (1 ft 8 in) thick. The guide walls are constructed on the ground surface to outline the desired slurry trench and guide the excavation machinery. Excavation is done using a special clamshell-shaped digger or a hydromill trench cutter, suspended from a crane.

Once a particular length of trench is reached, a reinforcing cage is lowered into the slurry-filled pit and the pit is filled with concrete from the bottom up using tremie pipes. The heavier concrete displaces the bentonite slurry, which is pumped out, filtered, and stored in tanks for use in the next wall segment, or recycled.

Desludging of a fish pond

10 acres of fish ponds faced the issue of decreasing water levels due to continuous sedimentation. The customer needed to remove the sludge from the ponds and while doing so, he wanted to increase the depth of the ponds. Instead of hiring excavators that would cost a lot of money and time, the customer turned to our Tsurumi partner in Hungary, Verbis.
