The seal can be internally or externally mounted. One of our fluid sealing experts will be glad to assist you in choosing the right seal for your job.
Mechanical seals are designed to prevent leakage between a rotating shaft and its housing under conditions of extreme pressure, shaft speed and temperature. Mechanical seals can be single acting or double acting.
Important shaft size and service limits to consider when searching for mechanical seals include nominal shaft diameter, shaft speed, alternate shaft or rubbing speed, operating pressure, and operating temperature. Common features for mechanical seals include balanced or unbalanced construction, dependent on direction or rotation or independent of direction of rotation, capability to handle slurries, and encased spring element.
The direction of the shaft rotation is also important to consider. This is the direction of a shaft's rotation as seen from the drive. Mechanical seals that are dependant on the direction of rotation are those that transmit torque using a conical spring or those that are equipped with a pumping screw. The direction can be clockwise or counter-clockwise.
