4FR Submersible pumps 4"
4FR Submersible pumps 4"
SKU:4FR040-11
Series of new concept 4" submersible pumps, designed and built for maximum resistance against sand (up to 250 g/m3) and other impurities. Materials certified for use in drinking water which allow the pump to operate even dry without deteriorating.
The supports are made of AISI 304 steel, obtained with a micro-casting process, guaranteeing extreme robustness and reliability to the product.
The new independent floating impeller design (patented) guarantees a low axial load on the motor.
The check valve is integrated into the head to support the weight of the water column and to protect against water hammer. The use can be continuous and can work in both vertical and horizontal positions.
