Submersible Grinder Pump SEG.40.12.2.1.502

The Grundfos SEG.40.12.2.1.502 submersible grinder pump is designed for the efficient transport of wastewater, sludge-laden water, and sewage in both domestic and commercial applications. It is particularly suitable for use in rural areas or difficult-to-access terrains where gravity drainage systems are not available and a pressurised system is required. This model incorporates an advanced grinding system that breaks down solids present in the wastewater, allowing them to pass through smaller-diameter pipes efficiently.

Grundfos's patented grinding system converts destructible solids into small fragments, facilitating their pumping through narrow pipes, optimising waste evacuation in sparsely populated areas, villages, or agricultural zones. The Grundfos SEG.40.12.2.1.502 is a single-stage centrifugal pump with a horizontal discharge port, making it a versatile option for wastewater handling, especially in situations where conventional drainage systems are not feasible.

Manufactured with durable, wear-resistant materials such as cast iron for the casing and impeller, this pump is designed to offer reliable performance and a long service life. The corrosion-resistant stainless steel clamp securely fastens the motor to the pump casing, ensuring it remains in perfect working condition even in demanding environments. Additionally, the pump's smooth surfaces prevent dirt accumulation, facilitating maintenance and extending its lifespan.

One of the standout features of the SEG.40.12.2.1.502 is the SmartTrim system, which allows for easy adjustment of the impeller clearance to maximise pump efficiency throughout its service life. This design significantly reduces energy consumption and minimises maintenance and breakdown costs, while ensuring optimal and continuous performance.
