How it works

See what happens inside

No jargon — just a section through the part, with everything that moves, moving.

Why a mechanical seal stops your pump leaking

SHAFTPROCESS LIQUIDSTUFFING BOX · FIXEDGLANDSPRING LOADCARBONSiCDRY SIDENO LEAKTURNS WITH SHAFT12345DUTY Up to 25 bar · Up to 15 m/s

A section along the shaft. Everything sitting on the shaft turns with it; the hatched parts never move.

  1. 1
    The shaft turns

    Your pump shaft spins all day. Anything clamped to it spins with it.

  2. 2
    The spring pushes

    A spring behind the drive collar presses the rotating face towards the seat, and keeps pressing as the face slowly wears down.

  3. 3
    Rotating face

    Carbon face, locked to the shaft — it turns at full pump speed.

  4. 4
    Stationary seat

    The mating seat sits still in the gland, cushioned by an O-ring. It never turns.

  5. 5
    Where the sealing happens

    The two lapped faces run against each other with a liquid film only microns thick — thin enough to seal, thick enough to lubricate. That film is the whole product.
