Centrifugal pump e-GS

waterelectricsubmersible

Overview Multistage submersible pumps of the e-GS series are engineered for pumping clean or sandy water (maximum sand content 150 g/m³). Designed for 4-inch diameter wells with a maximum total pump diameter of 99 mm. Nominal flow options: 1, 2, 4, 6, 8, 12, 16 m³/h. Performance: up to 21 m³/h and up to 340 m head. Power supply: single-phase and three-phase, 50/60 Hz. Motor power range: 0.25–7.5 kW. Pumped fluid temperature up to 35 °C. Maximum immersion depth 300 m.

Features of e-GS submersible pumps

• Upper and lower bases made of precision-cast stainless steel for corrosion resistance and rigid motor attachment
• Abrasion-resistant construction suitable for sandy waters (max 150 g/m³)
• Hexagonal pump shaft ensures positive impeller drive
• Check valve integrated in the pump head prevents backflow and protects diffusers and impeller
• Separate pump and motor design; pumps can be coupled to 40S or L4C motors

Applications

• Water extraction from deep wells
• Pressure boosting
• Fire protection systems
• Industrial water supply
• Filtration systems
• Dewatering in mining
• Water treatment plants
• Reverse osmosis installations
• Groundwater abstraction
• Irrigation and sprinkler systems
