Mechanical seals are indispensable for sealing rotating shafts. They make sure that the fluid handled remains in the system, prevent emissions and thus protect the environment from contamination. High-quality shaft seals in the form of mechanical seals also ensure maximum economic efficiency and operating reliability for pumps. This is crucial because the majority of repairs arise due to sealing problems.
And this is where KSB’s mechanical seals can make a difference: as well as impressing with a robust design, they offer straightforward installation and optimal integration in the seal chamber – ensuring reliable and efficient system operation.
The PSS Shaft Seal is a mechanical face seal. The sealing surface is created between the flat surfaces of the rotating stainless-steel rotor and the stationary carbon flange. The stationary carbon flange is attached to the front side of the bellows with hose clamps, and the back end of the bellows fits over the stern tube and is secured with hose clamps. The stainless-steel rotor is fitted on the shaft in front of the carbon flange. The stainless-steel rotor compresses the bellows before the rotor is secured to the shaft with set screws. This compression (pre-load) maintains constant contact between the two flat faces of the stainless-steel rotor and carbon flange, allowing the PSS to compensate for the variable fore and aft movement due to propeller thrust. In addition, the carbon flange is over-bored to the shaft diameter allowing it to float around the shaft and thus compensate for most misalignment and vibration problems. The stainless-steel rotor is sealed to the shaft by two O-rings recessed into the collar"s bore. These O-rings rotate with the shaft and stainless-steel rotor and do not experience wear during operation.
Never repack a stuffing box or replace a lip seal again with the PSS Shaft Seal The PSS Shaft Seal is Bureau Veritas, ABS & RINA certified. he Packless Sealing System (PSS) Shaft Seal is a mechanical face seal that is created between a rotating stainless steel rotor and a stationary carbon stator. The carbon stator is attached to a convoluted rubber bellow and the back of the bellow is attached to the shaft log (stern-tube) of the boat with hose clamps. During installation, the stainless steel rotor is used to compress the convoluted bellow. The rotor is then secured to the shaft. The...

For All PSS Shaft Seal Kits ACCESSORIES MAINTENANCE KIT Prolong the life of your PSS Shaft Seal with a maintenance kit. As with any rubber hose below waterline, the PSS bellows must be inspected on a regular basis for any sign of wear, aging or chemical deterioration. PYI recommends that the bellows be replaced every 6 years. Bellows may need to be more frequently inspected in an environment where non-sealed batteries emit sulfuric acid. Sulfuric acid vapor will accelerate rubber deterioration, as will an ozonator. This is a cost effective way to expand the life of your PSS Shaft Seal....

Mechanical seals are usually made of moving rings, stationary rings, compression elements and sealing elements. These parts are tightly bonded to form a sealing surface to avoid leakage. The liquid in the sealed chamber causes the end face to press against the end face of the stationary ring, and the mechanical seal occurs on the end faces of the two rings and the adhesion is to maintain the compression of the component pressure. The pump can not only work in the state, but also adhere to the end of the paste to ensure that the sealing medium does not leak, and avoid impurities into the sealed end. The sealing element acts as a gap between the sealing ring and the shaft, the action of the static ring and the gap of the gland, and the oscillation of the pump with the elastic element. When running with other components of the pump, the condition of the mechanical seal is closely linked with the external conditions. Only if the parts, auxiliary sealing equipment and technical requirements are ensured that the mechanical seal works well.
First, we need to turn off the pump, and then clean and inspect each part of the pump. Second, remove the impeller by rotating it in the anticlockwise direction. Then take out the seal at the backside of the impeller, and place the mechanical seal on to the shaft. Fix the mechanical seal and screw the impeller onto the motor shaft. Here are some notes of installation:
With its wide range of designs, the mechanical seals can also be made of different materials. In fact, the seal face materials decide the service time of mechanical seals. The most popular materials include rubber, stainless steel, PTFE, carbon, ceramic, Sic, and TC.
In SEALCON, equipped with advanced CNC processing equipment, you can not only buy the mechanical seals, but also buy the mechanical spare parts: sealing rings, spring, O-ring, sleeve and gland. All of our products conform to the standard of DIN24960, EN12756, ISO3069 API610, API682.
