Abrasion-resistant corundum structural parts used for pumping equipment

Structural parts used in pumps - such as axial sealing rings in water pumps, ceramic seal seats, bearing housings, or friction rings. The functional surfaces of the products must be polished to a surface roughness Ra of 0.3-0.10 µm and a flatness of up to 0.6 µm. Made of AG 202 (C795) - sintered corundum ceramics containing 95% Al2O3.

Typical products

O-rings
