Aftermarket replacements for EagleBurgmann MG1 / MG12 / MG13 | AESSEAL B02 / B012 / B013 | Vulcan 19 / 192 / 193
The Luwint MG01, MG02 and MG03 range offers elastomer bellows mechanical seals for water, wastewater and general industrial pumping applications. Three fitting lengths and a choice of face materials, elastomers and stationary seats help match existing pump installations.
Whether you are replacing a worn seal or sourcing an alternative for scheduled maintenance, Luwint can help identify the correct combination for your pump and operating conditions.
Why Choose the MG01 / MG02 / MG03 Range
-
Three fitting lengths: Choose the appropriate version to match the available installation space.
-
Flexible bellows design: The elastomer bellows accommodates normal axial movement and maintains contact between the seal faces.
-
Shaft protection: The bellows seals against the shaft without a sliding secondary O-ring at that interface.
-
Bi-directional operation: Suitable for either direction of shaft rotation.
-
Material choices: Face and elastomer combinations can be selected for clean water, abrasive liquids and compatible process fluids.
-
Seat options: Available with G60 cup-mounted seats or G6 O-ring-mounted seats, depending on the required configuration.
Choosing the Correct Model
The three models share the same basic bellows seal design but have different rotary fitting lengths.
| Luwint model | EagleBurgmann reference | Fitting-length designation in the Luwint drawing |
|---|---|---|
| MG01 | MG1 | L1 — shortest of the three versions |
| MG02 | MG12 | L12 — extended version |
| MG03 | MG13 | L13 — longest of the three versions |
Matching the shaft diameter alone is insufficient. Confirm the rotary fitting length, stationary seat dimensions and installed working length before selecting a replacement.
Typical Operating Conditions
| Parameter | Catalogue rating |
|---|---|
| Shaft sizes | 10 mm–100 mm |
| Pressure | Up to 12 bar |
| Sliding speed | Up to 10 m/s |
| Temperature | −30 °C to +200 °C |
These figures describe the range’s catalogue limits. Actual operating capability depends on the face combination, elastomer, liquid and service conditions. Maximum pressure, speed and temperature should not be assumed to apply simultaneously.
Common Cross-References
| Luwint | EagleBurgmann / Burgmann | AESSEAL | Vulcan |
|---|---|---|---|
| MG01 | MG1 | B02 | 19 |
| MG02 | MG12 | B012 | 192 |
| MG03 | MG13 | B013 | 193 |
These references help identify the corresponding seal family. Replacement suitability depends on matching the shaft size, fitting length, seat arrangement and materials.
When requesting a quotation, include any suffixes or material codes shown on the existing seal or its packaging.
Where It Is Used in Australia
With the appropriate materials and dimensions, the range can be selected for applications such as:
-
Water supply, transfer and circulation pumps
-
Wastewater collection and treatment systems
-
Agricultural and irrigation pumps
-
Building services and industrial utility pumps
-
General process pumps handling compatible liquids
Selected MG03 configurations with G6 seats are also used in certain Grundfos pumps. Confirm the pump model and seal dimensions to identify the correct replacement.
Materials Available
-
Seal faces and seats: Carbon, Ceramic, Silicon Carbide (SiC), Sintered Silicon Carbide (SSiC) and Tungsten Carbide (TC)
-
Elastomers: Nitrile (NBR), EPDM and Viton / FKM
Carbon/Ceramic is a common choice for clean-water duties. SiC/SiC can be considered where greater abrasion resistance is required. Elastomer selection should suit both the liquid and operating temperature.
Ask us to confirm the available material combination for your size and application.
