Restores pump operation, improves water circulation, and helps the boiler system to efficient heating performance. Key benefits Restores circulation: Replaces worn or damaged rotor and impeller to recover pump flow and pressure for proper heat distribution. Serviceable and costeffective: Replacing the rotor/impeller is faster and less expensive than full pump replacement. Compatible fit: Specifically intended for DWP1550F and DWP1550G circulation pumps to ensure correct alignment and operation. Reliable operation: Helps reduce noise and vibration caused by worn pump internals and supports stable boiler performance. Features and attributes Functionality: Motor rotor and water leaves (impeller) assembly for circulation pumps; transfers motor torque into fluid movement inside the boiler loop. Compatibility: Matches DWP1550F and DWP1550G gas boiler circulation pump assemblies as specified in the product title. Construction: Engineered to meet the fit and functional requirements of the original pump design for dependable replacement performance. Performance: Restores intended flow characteristics and hydraulic balance of the circulation pump when installed correctly. Installation: Designed to be fitted into the original pump housing and coupled with the existing motor; installation should follow manufacturer procedures. Typical applications / use cases Residential boiler : a worn rotor/impeller in a DWP1550F/G gas boiler circulation pump to restore hotwater circulation in a home heating system. Routine maintenance for service technicians: Keep this spare part on hand for scheduled pump refurbishments or emergency callouts to minimize downtime. Small commercial boiler servicing: Use during of DWP1550F/Gequipped systems in small commercial or multifamily properties where rapid restoration of heating is required. Installation and maintenance notes For safe and correct replacement, installation should be performed by a qualified technician familiar with DWP1550F/G boiler models and circulation pumps. Inspect related seals, bearings, and the pump housing during replacement; worn auxiliary components to ensure lasting performance. Verify pump alignment and secure mounting before returning the boiler to service; follow all safety and commissioning checks recommended by the boiler manufacturer. What you get Motor rotor and water leaves (impeller) assembly specified for DWP1550F and DWP1550G gas boiler circulation pumps, intended as a spare/ component to restore pump function and system performance.
