Tsurumi KTV3-55 Aluminium Alloy Large-Volume Submersible Drainage Pump for Civil Works with Vortex Impeller

Civil engineering projects with substantial dewatering requirements will find this portable submersible pump particularly effective. It is designed specifically for moving large volumes of drainage water and sand-carrying water from excavations where rapid water transfer is essential to maintaining progress. The die-casted aluminium alloy body combines durability with portability, facilitating deployment across large construction sites.

Flow capacity reaches up to 980 L/Min, driven by a 5.5 kW / 415v motor that also achieves a maximum head of 35 m. This hydraulic performance provides the pressure required for vertical discharge, enabling water to be lifted and directed away from excavation areas. The motor maintains stable operation in water containing up to 10% dry matter and across a pH range of 5 to 9, making it suitable for chemically variable site drainage.

Solids handling is managed by a high-gap vortex impeller made of ductile cast iron, allowing particles up to 8.5 mm to pass through without blocking the pump. The impeller design promotes efficient movement of abrasive particles through the housing while resisting erosive wear. This configuration ensures sustained pumping efficiency even when handling sand-laden runoff and abrasive site debris during large-scale dewatering operations.

An oil chamber houses a double-face mechanical seal with silicon carbide faces, incorporating the Oil Lifter to ensure consistent lubrication even at low oil levels. Motor cooling is provided by the top-discharge, side-flow design, which maintains thermal stability during extended operation. The anti-wicking cable entry and circle thermal protector provide comprehensive motor protection against moisture and overheating.
