The SIFCO Process Variable Speed ID Plater consists of a variable speed drive unit attached to a non-rotating, insulated, corrosion-resistant polypropylene base and flow chamber assembly. The flow chamber contains a high-quality mechanical solution seal which is made from corrosion-resistant stainless steel, graphite and ceramic. A hollow stainless steel shaft is used to rotate the plating tools, with a copper-graphite brush contact to conduct plating current up to 150 amp. Plating solution is conveyed to the tools with vinyl tubing and nylon fittings. The plating anodes are secured to the shaft by using the hub and one of the three sets of included titanium leaf springs. Twenty four stainless steel mounting screws are provided to mount the anode to the spring arms. Optionally, small-sized anodes may be secured by using an IDP Adapter (not included) to rotate tools such as the SIFCO ID Series anodes. A custom hub assembly or extension can be used to plate larger bore sizes.
