Mechanical Seals

The Type 502 mechanical seal is one of the best-performing rubber bellows seals available. It is suitable for general service and provides excellent performance in a wide range of hot water and mild chemical duties. It is specifically designed for confined spaces and limited gland lengths.

The Type 21, a general purpose seal, has become an industry standard with OEM designers. Made of stainless steel, it provides a service range well beyond that which is possible with comparably priced seals of other metallurgical construction. Complies with DIN 24960

The EA560 is self-adjusting to shaft misalignments and deflections because of the loosely inserted seal face as well as the ability of the bellows to stretch and tighten. The length of the contact area of the bellows with the shaft is an optimum compromise between ease of assembly (less friction) and sufficient adhesive force for torque transmission. Additionally the seal fulfills very specific leakage requirements.

The EA560D is double seal that is self-adjusting to shaft misalignments and deflections because of the loosely inserted seal face as well as the ability of the bellows to stretch and tighten. The length of the contact area of the bellows with the shaft is an optimum compromise between ease of assembly (less friction) and sufficient adhesive force for torque transmission. Additionally the seal fulfills very specific leakage requirements.

The Burgmann style MG1 mechanical seal is ideal for plain shafts:     

Elastomer O-ring Seal

A DIN seal for general low- to medium-pressure duties in the processing, refinery and petrochemical industries. Alternative seat designs and material options are available to suit product and operating conditions of applications. Typical applications include oils, solvents, water and refrigerants, in addition to a multitude of chemical solutions.

• For plain shafts
• Single seal
• Unbalanced
• Super-Sinus-spring or multiple springs rotating
• Independent of direction of rotation
• Pumping screw for media with higher viscosity (M7..F)
• Variant with PTFE secondary seals for high chemical resistance (M78N)

• Universal application opportunities
• Extended selection of materials
• Insensitive to low solids contents
• Flexibility in torque transmissions
• Self cleaning effect
• Short installation length possible

These are designed around O Ring pusher technology. They feature wave spring arrangements and short length working lengths.

 These seals can be installed internally or externally and are most commonly used on rotary lobe pumps.

These are similar in design to the Roten 3 but with differing seat dimensions compared to the Roten 3.

This is a particularly economic mechanical seal, highly valuable and with interchangeable components.
The basic pairing Ceramic-Carbon provides TYPE 3 with a vast field of applications also with dirty liquids.
Its metallic parts are in stainless steel and the gaskets may be in various kinds of elastomer, which again widens the range of possible applications. It is produced in large amounts for the most usual shaft diameters, from 10 to 50 mm.
Pump manufacturers as well as installers and users appreciate its technical and construction features and its vast field of applications.

This compact, unitized, single-spring, elastomer bellows mechanical seal is designed for use in small centrifugal water pumps, deep- and shallow-well jet pumps, pool and spa pumps and wastewater pumps.

The bellows is compressed onto the shaft pre-venting movement, and any premature wear of the bellows. Self aligning by design, the seal will compensate for bearing play, or slight geometric defects of the system.
