Submersible drainage pump J 205

One investment, years of cost-efficient pumping

The low weight and compact design of the submersible drainage pump J 205 ensure convenient transport, handling, and installation. The pump is ideal for pumping water and dirty water mixed with light abrasives. 50 Hz: head max 72 meters, flow max 102 l/s. 60 Hz: head max 85.5 meters (280 feet), flow max 106 l/s (1683 gpm).

Submersible drainage pump J 205
Main benefits
  • Easy start – plug in without worrying about overheating
    Built-in contactor connected to the thermal sensors 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 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 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
  • Dewatering in construction
    From roads and bridges to tunnels and dams, construction sites are difficult places to work. Construction site managers need solid economic reasons for purchasing equipment. Our dewatering pumps provide them.

  • Dewatering in mines
    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.
