MOR SAF series is a heavy‑duty, balanced, cartridge‑style high pressure mechanical seal specifically engineered for extreme pressure applications in centrifugal pumps, high‑pressure pipelines, injection pumps, and process equipment. It features a rugged, fully engineered structure designed to maintain stable sealing performance under high pressure, high temperature, and severe operating conditions.

Key Features

High-pressure balanced design: Hydraulically balanced seal faces minimize face loading, enabling reliable operation at elevated pressures.

Cartridge unitized construction: Pre-assembled and pre-set for error‑free installation, eliminating on-site adjustment.

Robust multi-spring or metal bellows structure: Ensures consistent face loading and strong resistance to vibration, shaft runout, and pressure shocks.

Reinforced seal chamber and gland: Heavy-duty design prevents distortion and maintains face flatness under high pressure.

Integrated shaft sleeve: Protects the shaft from wear, corrosion, and high‑speed abrasion.

Bidirectional rotation: Suitable for pumps operating in either rotational direction.
