MG9 Rubber Bellows Pump Seal
Core Configuration Selection Recommendations (Technical & Cost Balance)
1. Bellows Material – The Core Factor Determining Seal Life
The performance of the MG9 seal is highly dependent on the elastomer compound. Selection must be based on fluid compatibility and temperature.
| Material Option | Optimal Service Conditions | Media to Avoid | Procurement Consideration |
|---|---|---|---|
| Nitrile Rubber (NBR) | Cost-sensitive applications with water, oils, greases at temperatures ≤ 80°C. | Ozone, ketones, esters, strong oxidizing agents. | The economical choice for standard water and oil services. |
| Ethylene Propylene Diene Monomer (EPDM) | Hot water, steam, alkaline solutions, cold water, low-pressure steam at temperatures ≤ 120°C. | Mineral oils, greases, most hydrocarbon solvents. | Primary choice for hot water/steam duties, offers excellent aging resistance. |
| Fluoroelastomer (FKM/Viton®) | Broad range of chemicals, oils, high-temperature media. Good temperature resistance up to ~180°C (varies by grade). | Hot water/steam (risk of hydrolysis), ketones, ammonia. | General-purpose chemical resistance. Strong overall performance, a common industrial standard. |
Procurement Advice: Never order by the base model "MG9" alone. The material suffix code is critical. Always specify the full compound designation, e.g., MG9-EPDM or MG9-FKM.
2. Seal Face Combination – Influencing Wear Resistance & Heat Dissipation
Standard & Cost-Effective: Silicon Carbide (SiC) / Resin-Impregnated Carbon-Graphite. Suitable for the vast majority of applications with clean fluids (water, chemicals without hard particles). This is the most cost-effective procurement option.
Enhanced Wear-Resistant: Silicon Carbide (SiC) / Silicon Carbide (SiC). Recommended for media containing fine suspended solids (e.g., cooling tower water, water with slight impurities). This pairing significantly extends service life. Although the initial procurement cost is higher, the Total Cost of Ownership (TCO) may be lower due to reduced downtime and replacement frequency.

| Spring and Metal Parts | SUS304, SUS316 |
| Stationary Ring | Car / SIC /TC/Cer |
Advantages:
• Spring unit averted from the product so no sticking and clogging of the springs
• Safe operation (no fractures) because of seal face locking by square pin
• Suitable for pressure reversals
• Operation in vacuum without additional seat locking possible
• No damage of the shaft by a dynamically loaded O-Ring
• Small installation sizes
• Best suitable for conversions, no adaptations of the pump
• Insensitive to solid containing and abrasive media
• Advantages of a balanced seal even with plain shafts
• Insensitive to shaft movements because of the stationary design
Application:
General Industrial Water Pumps: For sealing clean water, cooling water, and low-pressure hot water in standard centrifugal pumps.
Chemical Process Pumps (Mild Services): Suitable for handling mild alkaline solutions, certain diluted acids, and solvents where the rubber material is chemically compatible.
HVAC and Circulation Pumps: Used in heating, ventilation, air conditioning, and hot water circulation systems.
Irrigation and Agricultural Water Pumps: Applied in pumps for transferring river water, lake water, or treated wastewater.
Marine and Shipboard Pumps: Used for general sea water (with compatible material selection), ballast, and bilge pumping duties.
