3D Model Description

Introduction

Mechanical seals seal the ‘wet’ part of a pump and prevent leakage out of the intended wet area.

In the past, gland packing (a.k.a. compression packing) was used to complete the same task that a mechanical seal currently does, but gland packing has several disadvantages compared to modern mechanical seal designs. Some of these disadvantages include:

  • Gland packing presses physically against the shaft and slowly wears away, which allows leakage.
  • The gland rubs on the shaft and slowly creates a groove on the shaft which may later need to be repaired.
  • Contact between the gland and shaft creates friction and this heat must be removed to prevent damage to the shaft and gland.
  • Friction between the gland and the shaft means that the pump motor has to work harder and thus a drop in efficiency occurs.

Despite its disadvantages, gland packing is still the cheaper of the two sealing options and remains in use.
