filling, commissioning, prolonged standstill and start-up after
prolonged standstill.
- If the operating company cannot ensure that the sealing chamber
and the containment shell of a magnetic coupling are always filled
with liquid during pump operation, appropriate protective and
monitoring measures must be taken to ensure this.
Monitoring parameters: Dry running in the pump interior and
seal chamber

5.4.1 Seal supply systems
Continuous supply of sealing medium to the seal prevents dry running during normal
operation. Before each start-up of the pump, any installed supply system must be
correctly connected and put into operation (existing sensors must be implemented in
the ignition protection system).
Information and instructions for the correct connection or design of the supply system
are co
ntained in the operator’s manual and assembly instructions or in the order-
related documents.
In case of doubt or for more information, please contact
Fristam
Pumpen.
The operating company is responsible for the correct connection or design of the
supply system, suitability of the components and devices of the sealing system, as
well as for trouble-free operation and maintenance.
Danger of explosion!
- Improperly connected supply system, incorrect sealing medium,
and incorrect operation may result in damage to the seal and
inadmissible temperature increases.
5.4.2 Lubricant
Synchronous gearboxes, bearing blocks, and compact bearing supports are usually
supplied filled with lubricant. In magnetic couplings, the pumping medium is the
lubricant.
Information on the lubricant for motors and geared motors can be found in the
manufacturer's documentation.
Synchronous gearbox: FKL/FK/FL/FDS
Version of bearing block or compact bearing support: FP/FPH/FSP/FZ/FPC
Version with magnetic coupling: FPM/FSM/FZM
