Lowara DOMO GRI15 Submersible Grinder/Macerator Pumps for Dirty Water Compact, hardworking, heavy duty grinder pump

The Lowara DOMO GRI15 1.50kW Submersible Grinder Pump is a robust and reliable wastewater pump designed for handling dirty water and sewage containing solids and fibrous materials. Equipped with a high-performance stainless steel grinding system, the pump efficiently macerates solids before discharge, helping prevent blockages and ensuring smooth operation in demanding drainage and wastewater applications.

Built with a heavy-duty cast iron hydraulic body and stainless steel motor casing, the DOMO GRI15 is engineered for durability, corrosion resistance, and long service life. The pump is fitted with a powerful 1.5kW motor and high-efficiency hydraulic design, delivering reliable performance with flows up to 30LPM and pressures up to 290kPa.

The DOMO GRI15 features double mechanical seals with silicon carbide faces for superior protection against abrasive liquids and extended pump life. Designed for submerged installation, the pump also includes a float switch for automatic operation, making it ideal for residential, commercial, and light industrial wastewater applications.
