4" submersible well pumps with motor - lowara 4gs series

GS+4OS Series - Lowara Submersible Pumps for Lightly Sandy Clean Water

GS Submersible Pumps and 4OS Motors Range Lowara's GS Multistage Centrifugal Submersible Electric Pumps with 4OS Motors are designed for efficient pumping and handling of clean water with a maximum suspended sand content of 150 g/m³. Ideal for use in deep water wells as small as 4" in diameter, these pumps boast high efficiency and rugged construction due to the use of AISI 304 stainless steel in the shrouds, motor case, cable covers, suction and discharge supports, and many other components.

Key Features:

• Strength and Durability: With floating impellers made of special technopolymer and low-friction diffusers, GS & 4OS pumps are extremely resistant to wear and abrasion.
• Rugged Construction: The use of stainless steel obtained by investment casting in the delivery and motor supports ensures resistance to galvanic currents and corrosion.
• Simplified Maintenance: Possibility to replace only the motor part or the hydraulic part, making maintenance easier and more convenient.
• Hydraulic Efficiency: Hexagonal section shaft ensures a secure grip on impellers, while treated bushings ensure no structural failure.
• Integrated Check Valve: Stainless steel valve with high hydraulic strength protects impellers and diffusers, discharging water column weight and water hammer.
• 4OS Electric Motor: Extremely durable, with high axial thrust capacity (up to 6500 N in motors from 3kW to 7.5 kW). Coolant and lubricant conforms to F.D.A. regulations, ensuring safety and reliability.
