The Lubi LSJ & LSW series Stainless steel submersible pumps are designed for 4″ (DN 100 mm), 6″ (DN 150 mm), 8″ (DN 200mm) and 10″ (DN 250 mm) bore well pumps applications.
All pumps feature complete fabricated stainless steel AISI 304 construction. All pumps are equipped with water lubricated rubber wear rings and bush bearings to work well with sand, found in well water. These pumps offers higher pumping efficiency due to state-of the-art computerized hydraulic design and usage of stainless steel sheet metal which offers a very low co-efficient of friction. This significantly reduces energy consumption. These pump can withstand harsh, abrasive and corrosive environment due to their construction in high grade AISI 304 stainless steel. All pumps are equipped with reliable non-return valve to prevent back flow and reduces water hammer when the pump is stopped. Insulation Class is F (Oil filled motors)
Pumps are designed for pumping clear and cold water that is free of air and gasses, thin, non-aggressive and non-explosive liquids without solid particles or fibers. Decreased pump performance and life expectancy can occur if the water is not cold and clear or contains air and/or gasses. The maximum sand content of the water must not exceed 50 g/m³. Higher sand content will increase the risk of blockage and reduce the pump life. When pumping liquids with a density higher than that of water, motors with correspondingly higher outputs must be used.
