HE950 Mechanical Seal

HE950-style mechanical seal (likely part of the Burgmann HJ92N/H7N family) is a balanced, spring-assisted, corrosion-resistant round cartridge seal, engineered for industrial applications involving pressures up to ~25 bar, temperatures from –50 °C to +220 °C, and shaft speeds up to ~3,600 RPM. Construction uses tough materials—SiC/TC/carbon faces, stainless or Hastelloy metal, and elastomers chosen per fluid compatibility. Dimensional specs (ID, OD, thickness, weight) vary by size and must be confirmed via datasheet. Certifications include ISO9001, and industry-grade warranties are standard


Balanced, single or dual, spring-actuated cartridge seal engineered for demanding industrial fluids and rotating shaft applications. Offers directional independence, robust corrosion resistance, and excellent performance under varying conditions.

• Seal faces: SiC, TC, carbon;

• Elastomers: NBR, EPDM, Viton, Aflas;

• Springs & metals: SS304/316, Hastelloy C‑4; optional 904L, Titanium
