The Hydraulic Pump Coupling Flange Retainer Plate serves to provide support and retention for the coupling flange within the hydraulic pump coupling assembly. It functions by securely holding the flange in place with the pump shaft assembly. It is a cylindrical component made of steel, precisely machined to match the dimensions of the flange. The retainer is installed with the shaft of the pump, providing a support structure for the coupling flange.Attributes:• Provided with a center hole to attach the plate to the shaft using 3/4" fasteners• Withstands high levels of stress and strainApplications:The Hydraulic Pump Coupling Flange Retainer Plate is used to securely retain the coupling flange and ensure proper support and alignment of the flange within the hydraulic pump coupling unit. This allows for smooth rotation of the flange along with the shaft and reduces the risk of misalignment, excessive vibrations, and premature wear.
