Boundary Pumps High-Flow Anti-Cavitation Backing Plate

• Plate is cut from billet steel reducing blow by and air ingestion

• Plates feature boundary's MartenWear surfaces for long life

• Increased volume and reduced foam increases engine bearing life

• Includes high pressure o-ring seal to eliminate leaks

This Billet back plates use advanced CFD simulation and exacting 3D precision milling to create a blend of engineering and manufacturing that produces less leak by, less aeration, less cavitation, and more high RPM flow.
