The correct operation and use of mechanical seals for pumps is critical to the impact on life. Generally speaking, the following precautions apply to the correct use of most mechanical seals.
Most mechanical seals for pumps are designed to work in a liquid environment, so the sealing surface must be immersed in liquid before the equipment is turned on. Dry running will seriously damage the sealing surface and affect the service and life of the mechanical seal. Of course, start the equipment to confirm that the motor rotation will not break the seal, but the mechanical seal of the equipment running at full speed must work in the liquid.
The piping system connected to the equipment must also be cleaned up. If the debris in the system is not cleaned up in time, the debris may enter the seal after long-term operation, thereby affecting the life of the mechanical seal. Premature failure of seals in new equipment is mostly due to this reason. Therefore, it is necessary to set a filter at the inlet before starting the new equipment.
Turn on the cooling or flushing system, whether the equipment is running or not, it is best not to cut off the cooling or flushing system, especially when the equipment is transporting a hot medium or the medium may crystallize after cooling.
