Mechanical seals

Mechanical seals

Mechanical seal is the type of seal to use in rotating equipment to guarantee sealing of the shaft that transmits mechanical energy to movable operating element of pumps, compressors, chemical reactors, vacuum filters-drying machines, mixing machines etc., i.e. where two operating environments need to be separated to guarantee minimal efflux. Such devices are applied in hydrocarbon process industry, food and pharmaceutical industries. Specifically pumps and mixing machines are used in production of alcoholic and nonalcoholic beverages, mineral water, oil, milk products, food supplements, food additives, pharmaceuticals etc.

Friction pair is the crucial component of the mechanical seal. Its material must have high wear-resistance and low frictional coefficient. According to its construction mechanical seals can be inner and outer, single and double.

The type of the seal’s construction largely depends on physicochemical properties of the environment for which the seal was designated: its state of aggregation (gas, liquid), pressure, temperature, viscosity, suspended solids and salts content, chemical aggressivity, flammability (while heating, in contact with atmospheric environment), potential health effects and environmental hazards.

The AvtokomTehnology group of companies is the official dealer of Kroma Ltd (Serbia), european mechanical seals manufacturer. We are ready to offer fine quality at a reasonable price.

Our specialists will select matching mechanical seals for pumps Grundfos, KSB, Hilge, Alfa Laval, APV, Wilo, Fristam, Ebara etc, and analogs of mechanical seals AESSEAL, Burgmann, John Crane, Roten, Vulcan.

Various types of mechanical seals are represented in our catalogue, it allows to select best possible option for any production problems solution.

NM-1 / NM-12 / NM-13 Elastomer bellows mechanical seals
pcs.
  $0.00
Description

 

Mechanical seals with metal bellows are used if it is necessary to avoid using any elastomer components in the seals, for example, if they are used in the chemical processing industry. The main reason for rejecting elastomers, apart from their chemical disparity, also lies with the small temperature range for elastomer component application. More specifically, when either the maximum or the minimum temperature limit is exceeded, elsatomers will lose their function.

The production of metal bellows is based on connecting a big number of profiled lamels. The number of lamels is determined by the strength which the seal must achieve. The connection is welded.

Mechanical seals with metal bellows are suitable for use in operating conditions which are characterized by high temperature and high pressure. Besides, this type of seal can be used for sealing crystallizable liquids and liquids containing other solid substances, as the bellows are capable of self-purification based on the centrifugal force principle.

 

Analog:

Burgmann MF95N, John Crane 515 / 5515

 

Mechanical seals with metal bellows are recommended for sealing:

- highly contaminated liquids, including hydrochloric and acetic acids at elevated temperatures;

- oils and lubricants;

- water and juice;

- in the chemical and oil industries;

- in the organic chemical industry.

NMM-2 Metal bellows mechanical seal
pcs.

Description

DIN 24960

 

 

Disadvantages of the central spring design: uneven load distribution along the friction belt in the couple due to the non-perpendicularity of the spring ends in relation to its axis, resulting in the couple being subject to unilateral wear, a comparatively large size of the spring in the axial direction and its inefficiency for large-sized shafts.

Mechanical seals with a set of small cylindrical springs have a smaller axial size than central spring seals and have no limitations as to the shaft diameter. By using a set of small springs, it is possible to increase unification of the Mechanical seal design: one and the same spring can be used for sealing different diameters. The sealing force can be adjusted by changing the number of springs and keeping constant the axial movement of the rigid element. The seal design ensures its low-cost maintenance due to easily replaceable parts.  This kind of seal is often used in pumps at refineries, petrochemical plants and in the process industry. The secondary seal on the axis is completed by means of an O-ring or PTFE ring wedgewise.

The disadvantage of this kind of rigid elements is the small diameter (1 mm) of the spring wire, which makes its application in corrosive media limited.

The rigid element design based on a set of small springs is not recommended for use in media with solid inclusions.
The springs are quickly clogged with solid inclusions, which causes the rigid element to lose its axial movement ability.

The more compact version allows it to be used in pumps for heating, in sludge and fecal pumps, as well as in food industry pumps.

Name
NV-2 Mechanical seal with spring in metal case
pcs.
  $0.00
Description

DIN 24960

 

 

Seals with a corrugated spring are specifically recommended for use at thermal power stations. Apart from the fact that no cases of spring blocking have been observed, an additional advatnage is that it is possible to produce such seals with a smaller diameter, if necessary, but with the same spring pressure. Besides, the spring design envisages special metal frames, in which the springs are inserted, and the seal can be used whichever the direction of shaft rotation is.

A relieved version of the seal with one corrugated spring is available.

NV-3 Mechanical seal with wavy spring
pcs.
  $0.00
Description

DIN 24960

 

 

The following force factors impact the rotating ring of the friction couple: pressure, spring strength, friction of the rubber sealing ring on the shaft and average contact pressure.

The hydraulic relief results from contact pressure reduction in the friction couple, for which purpose the shaft is step-shaped.

Thus, a trouble-free and durable operation of the mechanical seal is ensured at a pressure of up to 25 bars and a speed of up to 20 m/s (the highets Р’РЎ parameter).

The mechanical seal of BV-1 type is often used in pumps in refineries, petrochemical plants and process industry.

The secondary seal is made on the shaft by means of an O-ring or PTFE ring wedgewise.

The seal design ensures low-cost maintenance due to the use of easily replaceable parts.

BV-1 Balanced mechanical seals
pcs.

Description

DIN 24960

 

 

The mechanical seal design of BV-2 type prevents the springs from contacting the delivery fluid and due to this problems which occur with other multi-spring seals are avoided. The profiled sealing surface of the rotating part provides for good hydraulic relief, making it possible to use the BV-2 type mechanical seal at a pressure of up to 40 bars.

Different types of sealing materials can be easily used due to the simple replacement process and commonality of the sealing surface.

The replacement of all seal components is easy and requires minimal cost, which makes seal repair an easy and inexpensive procedure.

By installing a case on the shaft in the seal location, or by having a shaft outpur with a different diameter in the seal location, the resulting seal design uses the pressure of the substance to balance forces on the sealing surfaces of the mechanical seal.

Thus, a trouble-free and durable operation of the mechanical seal is ensured at a pressure of up to 25 bars and a speed of up to 20 m/s (the highest ""DC"" value).

The sealing face combination is selected in accordance with the substance used and operating conditions.

The secondary seal is made of O-rings having a quality grade consistent with the substance.

The other elements of the seal are made of nickel chrome steel.
