DFC Drainage Submersible pumps for wastewater with entrained solids Applications Pumping of sewage with suspended solids and filaments. Emptying of sumps, septic tanks and wastewater discharge tanks. Draining of flooded excavations and marshy ground. Water display, fountains.

Equipment With 5 m power cord. Single-phase, with built-in automatic reset overload protection and capacitor box with on/off switch. Three-phase, overload protection to be provided by user (installed in the control box).

Materials Pump body and delivery seal in cast iron. (coated with polybutadiene varnish by electrophoresis at 180°C). Impeller, suction flange, support feet, shaft extension and motor casing in AISI 304 stainless steel. Mechanical seal in carbon/ceramic/ nitrile rubber. O-ring in nitrile rubber.

Limitations Maximum immersion depth: 5 m. Maximum liquid temperature: 50 °C with fully submerged pump; 25 °C with partially submerged pump. Passes solids up to: 50 mm.

Motor Squirrel cage motor in a dielectric, cooled with non-toxic oil, which ensures the lubrication of the ball bearings and more efficient cooling. IP 68 protection.
