GRUNDFOS WASTEWATER SRP range 3.0 – 24 kW Grundfos Submersible Recirculation Pumps A range of efficient and reliable submersible recirculation pumps for wastewater treatment plants Grundfos offers a range of dependable and highly efficient submersible recirculation pumps for wastewater treatment and flood control. The recirculation pumps are designed for years of continuous use in the toughest environments. The pumps are based on the same modular design and principles as the gear-driven Grundfos mixers and flowmakers, which ensures easier maintenance and service. All parts are manufactured from specially selected materials, and each component is thoroughly tested for reliability and durability before assembly. The Grundfos range of submersible recirculation pumps is based on planetary-gear driven impellers. The stainless steel hydraulic parts are designed for high efficiency under both light and heavy-duty operating conditions. The submersible recirculation pumps are available in the following dimensions: DN 300, DN 500 and DN 800 mm with a motor range from 3.0 to 24 kW. This provides the possibility of a capacity of up to 5,130 m3/h and a head up to 2.1 metre.
