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).

Main benefits

Plug-and-pump installation without having to worry about overheating.
Reliable, trouble-free operation also at low water levels.
High wear resistance ensures years of cost-efficient pumping.
Modular design increases serviceability and makes it easy to convert the pump for different hydraulic requirements.

Motor protection

Motor protection

Built-in thermal switches in the stator windings (140ºC / 284ºF, ±5), connected to built-in contactor, SoftDrive or to separate control box.

DI leakage sensor, but not in combination with built-in contactor or SoftDrive.

Discharge connections

4” (standard HD), 6” (standard ND), 8” hose connections

4”, 6”, 8” G/B.S.P. threaded connections

4”, 6”, 8” NPT threaded connections

Benefits

Plug-and-pump installation

Plug in without having to worry 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 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.

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.
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.
