Pump mounting screw Weishaupt

Weishaupt pump mounting screw (art. 972.151.006) is an original fastener designed to secure the high-pressure fuel pump to the housing of an oil or dual-fuel Weishaupt burner. This screw is used during repair and maintenance of burner equipment to replace lost, damaged, or deformed fasteners. Technical specifications Parameter Value Part numbers 972.151.006 Manufacturer Weishaupt (Germany) Purpose Securing the fuel pump to the burner housing or motor Material High-strength steel with anti-corrosion coating Features Original geometry, precise fit into mounting holes Note: Exact thread dimensions and length for this part number are not found in open sources. Dimensions may depend on the burner model and pump type. For accurate selection, it is recommended to compare the screw with the old original. Compatibility and application This screw is used in Weishaupt burners of the R, W, WM-G series and others where reliable fixation of the fuel pump is required. Typically, the pump is attached to the electric motor via a flexible coupling, and two or three bolts are used for its fastening, fitting into the slots of the pump housing. Weishaupt pumps usually have a splined connection for drive from the electric motor and are mounted on a flange. Incorrect pump alignment or loosening of its fastening leads to runout, vibration, coupling wear, and noise during burner operation. ⚠️ When replacement is required Replacement of the pump mounting screw is necessary in the following cases: Loss or damage of fasteners during pump removal during service Stripped threads or deformation of the screw due to overtightening or corrosion Vibration or extraneous noise during burner operation caused by loosening of the pump mounting Scheduled maintenance
