Pump-drive enquiries are a natural fit for NM couplings, but \u201cfor a water pump\u201d is still too little information to select a size. A useful quotation starts with motor speed, motor and pump shaft diameters, power or torque, pump type and the expected operating pattern.<\/p>\n
Replacement projects often begin with a photo of two red or dark hubs and a black element. That can identify the coupling family, but it cannot prove the bore, hub length or duty. Measure the shafts and capture the existing model marking before selecting a replacement.<\/p>\n
