GRUNDFOS SP 125-8 is a multi-stage submersible pump entirely made of stainless steel, offering extremely high corrosion resistance. This model is specifically designed for high efficiency and a long service life. The "125" designation typically indicates a maximum flow rate capacity (approximately 125 m³/hour), and "8" refers to the number of impellers (stages) within the pump. The stainless steel construction ensures safe and hygienic operation in various water qualities, including aggressive water. Its high-efficiency motor delivers maximum performance with low energy consumption. Wear-resistant bearings and sand protection ensure the pump's smooth operation even in sandy water conditions. Its modular design allows for easy maintenance and servicing.
