The Grundfos NL-G5/8 PE/V,E/C U2 suction strainer with non-return valve is an accessory designed for DME/DMS series dosing pumps. It is fitted to the lower end of the suction pipe or hose and ensures a reliable supply of the dosed medium to the pump. The integrated non-return valve prevents liquid backflow, while the built-in filter strainer (mesh size 0.8 mm) protects the pump dosing head from mechanical impurities. The body is made of durable polyethylene (PE), the ball valve is made of Viton (FKM), and the seal is EPDM – this combination ensures good chemical resistance to a wide range of aggressive dosing media.

The product is compatible with hoses of 4/6 mm, 6/9 mm, 6/12 mm and 9/12 mm diameters (internal/external diameter), allowing it to be used in various installation configurations of standard dosing systems.
