Long-lasting, hard-wearing, compact and convenient
The low weight and compact design of the submersible drainage pump J 604 ensure convenient transport, handling, and installation. The pump is ideal for pumping water and dirty water mixed with light abrasives. 50 Hz: head max 58 meters, flow max 330 l/s. 60 Hz: head max 70 meters (230 feet), flow max 340 l/s (5397 gpm).
Built-in thermal switches in the stator winding (140ºC / 284ºF, ±5).
DI leakage sensor in the junction box, DI leakage sensor in the oil chamber, thermal sensors at upper and lower bearing connected to a separate starter and control unit.
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.
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.
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.
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.
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.
