Davey Grinder Pumps: Trade-Quality Wastewater Solutions for New Zealand Homes and Commercial Projects

When it comes to reliable wastewater management, New Zealand homes and trade professionals trust the heavy-duty performance of Davey Grinder Pumps. Engineered to meet strict NZ standards, these submersible sump pumps are designed to tackle the toughest domestic and commercial sewage applications. Whether you are upgrading an existing septic system, managing grey and black water, or undertaking a new-build trade installation, Davey provides the ultimate peace of mind.

At the heart of the Davey Grinder Pump is a high-torque, solids-handling grinder inlet combined with a high-head open impeller. This powerful mechanism effortlessly shreds soft organic solids, sanitary items, rubber products, and even certain textiles in suspension, transforming waste into a fine slurry for efficient, clog-free pumping. It is the ideal choice for reliable septic effluent disposal and sump emptying across New Zealand.
