![]() Notes For the various stationary gland types and sizes on the market, DEPAC offers a series of single seals - like this one - without stationaries. |
Type 159
Convincing Arguments! DYNAMIC, unbalanced mechanical seals are produced for general applications. OEMs often buy this type of seal in large quantities. Whether the one or the other version is selected depends on the OEM's preferences or on the conditions of use or installation at the customer end. It is important to know that a dynamic mechanical seal with wedge design can damage the shaft surface with its axial movements. Such a seal should only be used therefore with shaft sleeves. On seal versions equipped with a set of small springs, the pressure exerted on the seal faces is better and more uniform. This should be taken into consideration when selecting a seal. It is easier to position mechanical seals when there are steps on the shaft sleeve, rotor or the like which can serve as locating shoulders. Preference should be given to stationary faces which have elastic bearings to cushion shocks and vibrations from the equipment as far as technically possible. |

Type 161 DIN 24960
Convincing Arguments! DYNAMIC,unbalanced mechanical seals are produced for general applications. OEMs often buy this type of seal in large quantities. Whether the one or the other version is selected depends on the OEM's preferences or on the conditions of use or installation at the customer end. It is important to know that a dynamic mechanical seal with O-ring can damage the shaft surface with its axial movements. Such a seal should only be used therefore with shaft sleeves. It is easier to position mechanical seals when there are steps on the shaft sleeve, rotor or the like which can serve as locating shoulders. If this is not possible you can use locating rings with set screws against the shaft / sleeve. Preference should be given to stationary faces which have elastic bearings to cushion shocks and vibrations from the equipment as far as technically possible. |

![]() Notes The bellows are best seated when the surfaces of the shaft and sleeve are not too smooth or polished. It is advisable to install the bellows with the help of low-surface-tension water as lubricant (do not use oil or grease). Stationaries for Type 170 INCH are usually selected in accordance with the given installation dimensions. The dimensions L2 and L7 are derived accordingly from the stationary part. |
Type 170
Convincing Arguments! DEPAC offers a complete, attractively priced range of mechanical seals with elastomer bellows specially for OEMs. The various types are designed for applications in the most diverse installation spaces. Using elastomer bellows has many advantages:
This low-cost mechanical seal alternative is a good choice particularly for high-volume requirements! |

Type 175 A DIN 24960
Convincing Arguments! The large range of DEPAC mechanical seals developed specially for OEMs also includes a group of seals with "short bellows". All seal versions can be used with various stationary faces. The stationaries which should be given preference for design-related reasons are indicated in the descriptions. Notes The cups are best seated when the surfaces of the shaft and sleeve are not too smooth or polished. It is advisable to install the cups with the help of low-surface-tension water as lubricant (do not use oil or grease). Type 175 is also available in corresponding inch dimensions. Information and delivery on request. |

Type 140
Convincing Arguments! Balanced mechanical seals work with lower face pressure. This means lower face friction and therefore less wear on the face pair. The mechanical seal lasts longer! Seals for mounting on the outside are the answer when there is little room in the stuffing box. As an additional benefit, no metal comes into contact with the medium. This mechanical seal is an economical option for highly aggressive media. |

Type 186 DIN 24960
Convincing Arguments! Balanced mechanical seals work with lower face pressure. This means lower face friction and therefore less wear on the face pair. The mechanical seal lasts longer! The O-ring mechanical seal Type 186 has a self-cleaning effect when media containing solid materials are used. The solid materials are unable to settle and the secondary seal moves "away" from the solids if wear occurs. Notes The mechanical seals with mounting dimensions and length dimensions produced specially for DIN 24960 can also be used of course in all other stuffing boxes. DEPAC also offers these mechanical seals as special versions with larger dimensions than the listed standard sizes. For O-ring dimensions or their "dash" numbers please ask us or one of our contracted partners. (This information is also available in every installation manual.) |
