MASTER 5 - 2.2 kW / 50 Hz - sewage pump with grinder Hmax = 30
Couldn't load pickup availability
Pump designed for pumping dirty liquids with suspended solid 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 solid or fibrous bodies from single-family houses, small housing estates, camping sites, hotels or service outlets.
Fragmentation of solid particles into small fragments (45,000 cuts per minute) and high pressure generated by the pump allow you to overcome significant level differences and resistances in narrow pipelines.
The horizontal MASTER connection allows installation on a coupling foot, which can be purchased as a separate product.
