Axx, Axx 21, Axx 12

Mechanical seal with a simple, compact design for all-purpose use and in particular in applications with moderate pressures (up to 14 kg/cm2) such as pumps and compressors.

AxA, AxA 19, AxD, AxD 1, AxF

Mechanical seal with a simple design for general use. Type 104 is a standardised model in accordance with EN 12756 (KU).

AxB

Seal with a compact design for applications with low demands that require small diameters and often used for water pumps.

AxC, AxC 1, AxC 2

Mechanical seal with a compact design and small dimensions which is ideal for simple hydromassage or drinking water pumps.
The rotating part is attached to the pump impeller, rotates together with it. The stationary part is secured to the housing on its external diameter.

AxG, AxG 5, AxG 1121, AxG 1421

A versatile, robust single seal that is widely used in many different industrial and household applica- tions.
The different type 107 varieties can be combined with a wide range of stationary parts, thereby increasing its versatility due to the combination of different materials and working lengths.

AFx

This mechanical seal model is mostly made of PTFE and other materials that are resistant to chemically aggressive products. The metal parts are isolated from the process uid.

BEx 18, BEx 1121-18, BEx 1421-18

An extremely versatile general-use mechanical seal. It has metal tabs that reduce fatigue and tension in the rubber bellow when in the working position.
A balanced seal without the need for a stepped shaft. The seal can operate in applications with high pres- sures without suffering premature wear.

CxC

Mechanical Seal with a simple design for general use.

Exx

A balanced seal without the need for a stepped shaft. The casing of the rotating part protects the bellows from abrasion and from the rotation transmission tensions, and the spring from blocking in the event of being contaminated by bres and particles.
It is recommended for use with highly viscous or sticky uids containing bres or particles, or with uids that produce a chemical attack on the shaft.

HDx

Balanced by the bellows, without the need for a stepped shaft (models LWS10B, LMS20B). Suitable for working in applications with high pressures. The O-ring resting on the shaft does not cause wear as there is no axial movement (changes in pressure). Recommended for working with sticky or viscous uids that require cleaning processes (CIP) or sterili- sation processes (SIP) in situ due to the geometry of the spiral-wound bellows.
This seal may be supplied with any of the statio- nary parts shown in pages 59 and 60. for mea- surements in mm, and 61 for the measurements in inches.

HEx

Internally balanced, with no need for a stepped shaft (models LWS10B, LMS20B). The O-ring resting on the shaft does not cause wear as there is no axial movement. Appropriate for applications with sticky or high viscosity uids as its open leaf design genera- tes a self-cleaning effect. In addition it is suitable for application at moderate pressures and high tempe- ratures (for up to 400o C please enquire) and very aggressive uids in chemical and mechanical terms. Very often used in compressors.

118 / CxA

Economic mechanical seal with small dimensions, used in large household pump productions for re- circulating water or for working conditions with low demands.

161412

Mechanical seal with a simple design for general use.
