Benefits

Plug-and-pump installation

Plug in without having to worry about overheating. Built-in thermal protection protects the motor from overheating.

Wear resistance

One investment for years of cost-efficient pumping. Impeller in high chrome alloy steel ensures a long lifetime and high efficiency.

Reliable operation - minimizes maintenance time

Double outer casing and good heat convection enable the pump to operate continuously at low levels or even run dry without damaging the motor.

Serviceability

Save time and money with easy on-site service. Modular design lowers the overall service costs. By removing the top cover of the pump, you can easily check the electrical junction box. Environmentally safe white oil is used in the oil casing for easy inspection of seal conditions.

Applications
  • AquaTronic - the intelligent option
    The world’s smartest dewatering pumps for applications in mines, construction sites and tunnels are equipped with the innovative AquaTronic. AquaTronic ensures correct motor rotation, gives motor protection, allows the pump to start via a level sensor, and gives you all the pump performance information in your PC, plus much more.

  • Dewatering in construction
    From roads and bridges to ditches and dams, construction sites are difficult places to work. Construction site managers need solid economic reasons for purchasing equipment. Our submersible dewatering pumps provide them.

  • Dewatering in tunneling
    A tunnel construction is a complex worksite were many different variables need to be taken into consideration, flooding is one of them. Our drainage and sludge submersible dewatering pumps are lightweight, portable and start when you plug them in.

  • Flood control
    Climate change is challenging natural disaster prevention. When water runs off the land in large quantities, Sulzer’s comprehensive range of pumps provide reliable, cost effective and efficient solutions for flood control.

  • Mine water management
    Sulzer offers a comprehensive portfolio of pumps and process equipment for abrasive and corrosive environments in mine water management applications.
