Motor protection

  • Thermal control system with temperature sensors in the motor windings for automatic shut-down in case of overheating
  • Seal monitoring system with leakage sensor in the junction box and motor chamber for automatic shut-down if water has entered the pump
  • Leakage sensor in the oil chamber indicating presence of water in the oil
  • Optional bearing monitoring system with temperature sensors at upper and lower bearing indicating excessive temperature

Discharge connections

DN 100/4” (standard HD)
Flange connection PN40 DIN 1092-1
Flange connection class 250 ASME B16.1 1998

DN150 / 6” (standard ND)
Flange connection PN40 DIN1092-1

Benefits

Reliable operation

Strong cast iron construction with outer casing gives good cooling and enables the pump to run at operating water levels all the way down to the strainer.

Wear resistance

One investment for years of cost-efficient pumping. Impellers built back to back together with double exit volutes, and flow elbows in white cast iron ensure a long lifetime and high efficiency.

Flexible hydraulics

For easy conversion from ND to HD the pump is fitted with impellers and diffusers for both HD and ND versions. This give the option to stock fewer pumps and still have the right hydraulic performance for the job.

Applications
  • 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.

  • 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.

  • Mining
    Whether on the surface or underground, the conditions in mines are harsh. Besides the mud, slurry, stones, and rocks, there are large volumes of water to remove in order to keep production moving. Our dewatering pumps are rugged and ready, taking on the toughest drainage and sludge removal.

  • 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.

  • XJ 900 awarded Product of the Year
    September 24, 2021
    Sulzer is proud that our latest addition to the submersible pumps family, the XJ 900 submersible dewatering pump, has won the Product of the Year category in the Pump Industry Awards program.

  • Pump solutions for mine water management
    Mines require water. At the same time, because many mine working areas are below the water table, the removal of water is a major challenge. Water is critical for every mine site – without water the mine could not operate. Pumps are, therefore, one of the most used machines in mines today. In this article we will review the concepts of mine water and mine water management as well as the most common pumping applications. Read the whole article.

  • Expert solutions for mining and quarrying
    The mining, quarrying and construction industries present some of the most challenging applications encountered by pumps. The range of process fluids handled varies quite significantly across these processes, ranging from clear water to heavy slurries and from alkaline, pH neutral to highly corrosive fluids. As well as having to deal with the process requirements, products must also be compliant with the environmental and legislative constraints in play across geographies. Read the whole article.
