Cartridge Mechanical Seal Failures And How To Prevent Them

Cartridge Mechanical Pump Seal are frequently seen in pumps and rotating parts. They prevent leakages. These pre-assembled seals can be installed easily. However, the most excellent seals may become ineffective if they are not used appropriately. The most frequent seal problems will be covered in this handbook. You will also get to know how to prevent them and secure your equipment better.

Seal Faces Wear Very Quickly

Face wear is one of the causes of cartridge seal failure. The seal has its face constantly rubbing. They become worn out fast without sufficient lubrication. This may lead to leakage and loss of power. The primary cause of this is dry running with the incorrect fluid. To prevent this, it is necessary to monitor the level of fluid and to apply the appropriate product.

Wrongly Installed Seal

Occasionally, the installation of cartridge seals is done in reverse. They may be simple-looking, although it is possible to break them by improper fitting. Insufficient torque and misalignment could cause facial damage to Cartridge Mechanical Pump Seal. The seal will leak as long as it is not sitting properly. Never ignore the manual. Using a set of appropriate tools, properly install.

Excess Motion Within The System

The seal shakes and moves as a result of excessive vibration. This disrupts the face contact and ruins the surfaces. The vibration is normally the result of worn-out bearings or a shaft out of alignment. The effect of this is an insecure seal. Pump parts should be frequently cleaned. Align and adjust any vibration problem forthwith.

Heat Buildup Destroys the Seal

Mechanical seals require a cool surrounding. In case the pump is overheated, the seal faces can crack. The O-rings and elastomers are also harmed by heat. This frequently occurs during the times when there are obstructions in cooling systems. Clean the cooling lines and watch the levels of fluids. Cooling also makes your Cartridge Mechanical Pump Seal last a long time.

Improper Pressure in the Pump

Too much or too little pressure affects seal performance. The seal could be broken or bent out by too much pressure. Insufficient pressure will ensure that the seal does not fit. Both situations result in leakage. Use a pressure gauge. Make sure the seal is designed for your pump’s pressure level.

Foreign Particles Entering the Seal Area

Dirt or debris in the seal area can scratch the faces. This creates a channel for fluid to leak. Particles can also block the springs inside the seal. That stops them from moving freely. Use filters and clean fluids in your System. A new seal should never be installed until the pump has been flushed.

Incorrect Seal Material for the Fluid

Each seal is made for certain chemicals. Using the wrong material causes swelling, softening, or cracking. This breaks the seal quickly. Before choosing a seal, check the chemical compatibility. Talk to your supplier. Always pick materials that match your fluid type and working conditions.

Poor Storage Before Installation

It is possible for Cartridge Mechanical Pump Seal to sustain damage prior to installation. The faces may stretch or crack if improperly stored. Humidity and dust may destroy and loosen the seal. Seals must always be kept in a clean, dry environment. Until it's time to use them, keep them in their original packaging.
