OPERATION

Safe operation

ATTENTION!

If during an interruption of operation values deviating from the operating

conditions / operating limits the mechanical seal must be removed and checked
either at the manufacturer's or at the nearest service centre.

For a single mechanical seal the

pressure in the seal chamber

of the machine

(stuffing box pressure) has to be

higher

than the ambient pressure at the machine at

any time. Otherwise the machine will

suck in air

via the sliding faces, which will

result in

dry-running

and consequent

failure

of the mechanical seal.

During every state of operation,

the mechanical seal has to be constantly wetted

by the

medium

to be sealed

in its liquid form

, in particular when the machine is

started

stopped

. The machine design has to be such as to take this necessity into

consideration.

Damage due to dry-running is excluded from the warranty.

If the operation limit values and the instructions given in this manual are followed a
trouble-free operation of the mechanical seal can be expected.

Start-up

Safety checks before start-up



Torque transmission between mechanical seal and shaft duly installed



Supply connections tightened and pressure-sealed



Disposal connections installed environmentally safe

For a safe operation of the mechanical seal we

recommend applying

at inboard

the

most suitable

type of circulation

described in

API 610 / 682

. This measure protects

the seal cavity from deposition of solids.



Fill and vent the machine by all means in accordance with the instructions of the

machine manufacturer.



Now the seal is ready for operation.

To operate multiple seals special supply systems are required. Please contact
EagleBurgmann.
