Submersible Wastewater Pumps

  13/03/2009
The SL is an efficient option for sewage pumping stations in municipal network systems. The same advantages apply to sewage, effluent and surface water pumping stations in connection with commercial buildings.
 

Grundfos SL1 pump

The SL is flexible - when sized correctly, it offers you a solution that is optimised to the actual conditions in your system. Given the media properties and inflow data, including expected daily and seasonal variations, Grundfos  can begin the process of putting the pieces together. The right impeller, an EFF1-type motor with or without frequency converter, a prefabricated pumping station and a controller will create a pumping set-up to suit different situations.

 

Built-in monitoring and control

Picking the right control and monitoring system do more than any other single component. Maintenance needs become predictable with integrated analogue sensors. To indicate upcoming service needs, analogue sensors monitor trends in motor temperature, water-in-oil in the intermediate oil chamber and motor insulation resistance. An I/O 111 module equips the SL for any data communication task ahead.

 

The motor and pump can be separated in one easy move by opening the stainless steel clamp. The primary and secondary shaft seals are combined into a single cartridge unit that is easy to remove and replace. Seemingly minor details make a big difference that compounds over the pump's lifetime.

 

Another detail that stands out on the SL is the cable connection: the epoxy-filled, stainless-steel cable plug provides a totally sealed cable entry. This totally eliminates the risk of water entering the motor through the cable.
