MASTER 6 - 3 kW / 50 Hz - sewage pump with grinder

Pump designed for pumping dirty liquids with suspended solids or fibrous materials, with a fully open multi-vane inlet grinder system and hardened steel cutting edges. MASTER electric submersible pumps equipped with a grinder are particularly recommended for solving problems related to lifting sewage containing solids or fibrous materials from single-family homes, small housing estates, campsites, hotels or service points.

The fragmentation of solid particles into small fragments (45,000 cuts per minute) and the high pressure generated by the pump allow to overcome significant differences in levels and resistance in narrow pipelines.

The horizontal MASTER connection allows for mounting on a coupling foot, which can be purchased as a separate accessory.
