794431 Piston

The 794431 PISTON by Blackmer is a high-quality pump component designed for use in positive displacement and sliding vane pumps. Manufactured with precision, this piston ensures reliable operation and durability in demanding industrial applications. Supplied by KI Pumps of Waukesha, WI, a recognized global supplier of pump components and maintenance parts, the 794431 PISTON is constructed from corrosion-resistant materials, including high-grade alloy steel, to withstand hydraulic pressures up to 1000 PSI. Its dimensions include a length of 6.5 inches, a diameter of 3 inches, and a bore size of 2.75 inches, compatible with numerous Blackmer pump models. The piston features a wear-resistant surface finish with a 60 microinch surface roughness, resulting in minimized friction and extended service life. It is suitable for applications requiring pistons with a stroke length of 4 inches and fits within a cylinder bore diameter of 3 inches. Notable features include precision-machined sealing surfaces, a hardened piston head, and compatibility with common industrial lubricants. The 794431 PISTON is ideal for chemical processing, petroleum transfer, and industrial fluid handling, especially for users seeking reliable, OEM-quality pump components. The piston ships individually, without additional accessories, and requires proper lubrication during installation. Maintenance involves routine inspection for signs of wear such as scoring or pitting; replacement is recommended when these signs appear. Cleaning with solvent or mild degreasing agents is advised, and storing the piston in a dry environment helps prevent corrosion. This piston is a critical component for ensuring consistent pump performance and long service intervals in demanding hydraulic systems.
