Structural Features: double-end, multiple springs, with spring protector, balanced, independent direction of rotation, spring standing mechanical seal. The component is cartridge seal with easy installation. The springs are not touching the sealed mediums so that there will be no jam caused by the high viscosity and crystallization active content. This makes sure the flexibility of the compensation ring and as a result, it lasts the lifetime of the whole component. Multi spring structure makes the load on the sealing faces balanced. The seal needs to work with sealing water, which has the pressure of 0.1 - 0.3 MPa and flow rate of 3 - 8 L/min.

Scopes of Application: mainly used in chemical engineering, pulp production, pulp drying, pulp screening, and sewage treatment. Designed for pressure screens and other filters. This component can work as an alternative to ANDRITZ SafeMatic seal support system.

The shaft is protected in the way of bearings by stainless steel sleeves, where we normally use a mechanical seal to the high pressure for liquid handling. So we provide a separate lubricating arrangement. The oil within the seal chamber is maintained constantly one bar above the discharge pressure by an accumulator containing a plunger which is operated by air or nitrogen pressure.

It is preferable on a vertical pump to have shaft sealing at the pump upper end only. Mechanical seals are spring loaded to hold the sealing faces together. It is important that cooling and lubrication liquid is led to the mechanical seal from the lowest point on the pressure side of the pump to ensure that some liquid reaches there even when priming.

Special header tanks have been installed for seal lubrication in some applications. They must not run dry, and care must be taken to prevent ingress of foreign matter. Many mechanical seals incorporate a carbon face, and there is a possibility of electrolytic action in the presence of sea water. Normally this does not take place in boiler feed water pumps because we use the fresh water treated dosed with corrosion preventing chemicals as the boiler feed.

In the case of sea water pumps, we do not use the mechanical sealing arrangement- instead we use a soft packing arrangement. Stuffing box type glands may be packed with soft or metal foil type packing. The pump internal bearings may be lubricated and cooled by pumping liquid that is always available when the pump is running. A lubricator for the application of grease is also fitted in some circumstances.

The image below shows a mechanical seal arrangement. (Click to enlarge and then use the Back button in your browser to return to the same place in this article.) In the image, elements d1 and a1 bear and slide on each other, creating a seal at their interface. One group of parts is connected to the rotating shaft and the other to the machine’s case. The spring keeps the elements tight against each other, maintaining the seal and allowing for wear.

Shaft should be clearly examined especially in the area of mechanical seal arrangement if excessive wear has taken place the quality of packing used should be investigated and a larger amount of lubricant should be used while running.

Structural Features: double end, multiple springs, balanced, independent direction of rotation, still structure and set screw transmission. The component is cartridge seal with easy installation. The still spring design is good for high speed running and can take the vibration of the pumps. The springs are not having contact with the mediums so that there will be no jam or corrosion caused by the high viscosity and crystallization active content. The seal face load is well balanced and the seal can work with a wide range of sealant pressure (upto 0.5 MPa) and the cooling efficiency is high.
