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 > 2 Solutions for a variety of applications Wastewater treatment plants, pumping return sludge Flood control and other applications which require large flows at low heads Main features Oil-filled gearbox with tapered oil bearings Rewindable motor Two radial lip seals protecting the shaft seal No special tools needed for maintenance or service Built-in leak sensor Motor housing in cast iron, protected by a multi-layer two-component epoxy coating Pumping rack and hydraulic inlet in stainless steel Propeller in cast stainless steel 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 m 3 /h and a head up to 2.1 metre. Details > 3 State-of-the-art features and design Motor bracket Corrosion resistant motor bracket made from stain- less steel, galvanically separated from the motor housing. The motor bracket ensures easy installation and stable operation. Active electronic leak detector Indicates possible liquid in the gear housing. Even the smallest quan- tity will be quickly detected. Thus service can be carried out before any damage is done. Impeller Hydro-dynamic 3-blade impeller made from cast stainless steel. Two ball bearings The rotor shaft rests on two ball bearings, which accommodate both axial and radial forces. Cable Watertight cable entry with self-shaping seal preventing cable damage. Motor protection The motor is effectively protected against over- load and overheating by three thermal switches or three thermistors placed in each motor winding. Shaft sealing rings The radial shaft sealing rings protect the mecha- nical shaft seal system from abrasive parts. During maintenance, only the less expensive radial shaft sealing rings need to be changed. Planetary gear The best and most effi- cient solution to trans- port axial forces. Slim design provides opti- mum hydrodynamic shape. Material specifications and type key Technical data > 4 Material specifications Corrosion protection To ensure long and trouble-free operation, the cast-iron parts are protected against corrosion by a high-grade multi-layer corrosion system.

The data needed in order to select the SRP with the right specifications are: Required flow, Q – and total head, H. Calculation of head H = Hgeo + Hsystem, where Hgeo is the geodetic head (Hgeo = H 2 - H 1 ) and Hsystem is Head Loss in the system: Hsystem = Hj + Hjn + Hvalve Hj = Loss in pipe. Hj = λ x Hjn = Outlet loss. Hjn = Loss in elbows. Typical value 0.1 – 0.2 m Hvalve = Loss in valve. Typical value 0.05 – 0.25. Actual data from supplier shall be used. For more specific calculation please contact Grundfos. Symbols λ = Typical value 0.02 L = Pipe length [m] V = Velocity [m/sec] D = Pipe diameter [m] g = Gravity 9.81 Example: Q = 475 l/sec Hgeo = 0.35 m L = 21 m V = 2.4 m/sec D = 0.5 m There are no valves or elbows in the system. Calculation of loss in pipe Hj = 0.02 x = 0.25 m Calculation of outlet loss Hjn = = 0.30 m Determination of Head H = 0.35 m + 0.25 m + 0.3 m = 0.9 m By the use of selection curves for SRP.XX.50.XXX.27 (page 8) it can be determined that the SRP.80.50.378.27 meets the requirements and will deliver Q = 475 l/sec at H = 0.95 m.
