Rotating Face Mechanical Oil Seals

Rotating Face Mechanical oil seals:
Mechanical seals are engineered for most  pumps, mixer and agitator applications in maintenance. In many cases the designs have been proven to be workhorses over years of use. In others seals must be designed for evolving industrial demands.
Mechanical Seals deliver a full range or rotary configurations and component materials – to handle virtually and fluid moved by any equipment. When you specify engineered mechanical seals you have the advantage of the most advanced mechanical seal technology,nok seal, the latest in field proven design and when working with an outside sales force there is hands on technical support.Rotating Face Mechanical oil seals.
Rotating face units are the dependable mechanical seals answer for worn equipment when your shaft mechanical seals must be replaced.  They are ideal for new equipment designs or to improve the usefulness of existing equipment by converting from pump packing to mechanical seals.
Mechanical seals feature:

*Invisible leakage
*Less friction/power loss
*No to little wear on the shafts or sleeves
*Flexibility – to accommodate shaft deflections and “End Play”
*No period maintenance
*Long Life

In practical use, the basic rotating face mechanical seal principle is adaptable to serve a tremendous number of sealing needs: standard mechanical seals can suit most requirements-including temperatures to 500 degrees F and shaft speeds to 3600 RPM through the choice of secondary seal and the combination of seal and seat face materials which are offered.  Seals can be ordered in balanced configurations to seal pressures above 200 psi, or used in a multiple for extremely high pressures or especially severe fluid services….Special mechanical seals can be furnished to meet the most demanding of industrial applications considering pressure, temperature, speed or fluid.nok seal,
Mechanical seal designs range from the work horse “single spring” mechanical seals, to highly engineered double cartridge seals for extreme applications.  The basic of each type follows:
Single spring mechanical seals:

Utilize a single spring coiled in a right of left hand design to accommodate left and right hand turning pumps. They have the flexibility to accommodate misalignment, shaft deflection, and break away shock loading.  It resists clogging in extremely viscous fluids.Rotating Face Mechanical oil seals.
All mechanical seals are constructed of three basic sets of parts:
1) A set of primary seal faces: one that rotates and one that remains stationary.
2) A set of secondary seals known as shaft packings and insert mountings, such as o-rings, rubber boots, PTFE or Grafoil wedges, or V-Rings.nok seal.
3) Mechanical Seals have hardware including gland rings, collars, compression rings, pins, springs, retaining rings and bellows.Rotating Face Mechanical oil seals.
