Grundfos Introduces SL Submersible Wastewater Pumps
Send Via E-MailOLATHE, KS - October 15, 2010 - WastewaterPR.com - Designed for submerged use in network pumping stations, wastewater treatment plants, public buildings, housing projects and industry, SL pumps will handle municipal or industrial wastewater, wastewater with fibers, drainage and groundwater, process and cooling water. For even more demanding applications, a wide range of customizing possibilities is available; e.g., casted parts in various stainless steel grades.
Grundfos SL submersible pump
Grundfos has launched a new range of SL submersible wastewater pumps with the goal of minimizing known risk factors and reducing maintenance requirements and costs, while delivering years of reliably optimum service.
Designed for submerged use in network pumping stations, wastewater treatment plants, public buildings, housing projects and industry, SL pumps will handle municipal or industrial wastewater, wastewater with fibers, drainage and groundwater, process and cooling water. For even more demanding applications, a wide range of customizing possibilities is available; e.g., casted parts in various stainless steel grades.
The new SL range offers two types of impeller:
SLV/SuperVortex Impeller: This pump type provides the free passage of solids up to 4 inches (100 millimeters) in diameter, making it ideal for liquids with a content of solids, fibers or gassy sludge.
SL1/Channel Impeller: This pump type also accommodates solids up to four inches, but is designed particularly for large flows of raw sewage.
In minimizing risk factors, Grundfos SL pumps offer a number of special, innovative features:
Eff1-type motor: The use of Eff1 components boosts motor efficiency while prolonging pump life.
Moisture-proof plug: A two-component sealant filling the plug prevents moisture from entering the motor via the cable core.
Short rotor shaft: The compact construction of the pump motor reduces vibrations, protecting shaft seals and bearings.
Double mechanical shaft seal: Primary and secondary seals are combined into a single cartridge to cut maintenance time.
Easy-to-open clamp: This feature enables the motor to rotate 180 degrees for ready access during maintenance.
