MOR 318 is a pre-assembled, single‑acting, balanced single cartridge mechanical seal, designed for reliable sealing in centrifugal pumps, chemical pumps, sewage pumps and general process equipment. It features a compact cartridge structure for easy installation and stable performance in corrosive, abrasive and medium‑pressure operating conditions.

Key Features

Cartridge unitized design: Fully pre‑set and pre‑assembled, no on‑site adjustment or measurement required, effectively preventing installation errors.

Single balanced seal: Hydraulically balanced design reduces face load and heat generation, suitable for medium‑pressure applications.

Multi‑spring structure: Uniform face loading, strong compensation for shaft runout, vibration and wear.

Integrated shaft sleeve: Protects the pump shaft from abrasion and corrosion.

Bidirectional rotation: No need to distinguish rotation direction during installation.

Short axial length: Ideal for pumps with limited seal chamber space.
