Portable Dewatering Pumps

The HS-series is a submersible single-phase portable drainage pump. Though it is a single-phase unit, the pump has the durability equivalent to three-phase drainage pumps, since the wear parts are made of abrasion-resistant materials. The side discharge, spiral design allows smoother passage of the sucked solid matters. The shaft-mounted agitator prevents "Air Lock" that tends to take place on vortex or semi-vortex pumps.

Ground Stabilization Work on Reclaimed Land for a New Airport Runway

Hong Kong

Ground stabilization work is underway by DCM (Deep Cement Mixing) on land reclaimed for a third runway at Hong Kong International Airport. The job is employing a work barge outfitted with a mixing plant. The mixing plant is supported by a storage tank for holding seawater, two filtration tanks for filtering wash water after plant washdowns and a sedimentation tank for processing the filtered wash water.
Several of Tsurumi's submersible construction dewatering pumps and seawater-resistant pumps are being used as a part of operating this equipment.

Tsurumi's KTZ43.7 and KTZ411 seawater-resistant pumps (3 total) are being used to pump seawater to the storage tank and from the storage tank to the mixing plant.

The mixing plant needs to be washed down periodically. The wash water from that is pumped to two filtration tanks and, after filtering, to a sedimentation tank. Three of Tsurumi's KTZ32.2 submersible construction dewatering pumps are being used to move the wash water.

Other than wear in the galvanic anode, the pump shows no signs of corrosion. (KTZ411 seawater-resistant pump) Other than wear in the galvanic anode, the pump shows no signs of corrosion. (KTZ411 seawater-resistant pump)

Besides the KTZ pumps, an HS2.4S single-phase portable drainage pump is used on board the work barge to discharge rainwater from the pit and leftover drainage. By discharging this water, this pump is preventing seepage to lower decks.
