1. High-Performance Vacuum Boosting:

• Supercharge Pumps: The vacuum boosters significantly extend the performance of vacuum pumps by increasing pumping speeds and achieving deeper vacuum levels. This is essential for industries requiring high-performance vacuum systems.

2. Applications:

• The boosters are used across industries such as chemical manufacturing, petrochemical processes, plastics production, semiconductor fabrication, wood composites, food processing, vacuum furnace applications, and more.

3. Mechanical Seals:

• Rotor & Drive Shaft Seals: These vacuum boosters are equipped with mechanical seals on both the rotor and drive shafts for sealing and preventing leakage.
• Water-Cooled Drive Shaft Seal: Included for enhanced thermal management, ensuring that the booster operates efficiently under various conditions.
• Cooling Coils: Located in the end covers to manage heat build-up (Note: Cooling coils are not included with versions featuring optional motor mounting flanges).
• Noise Reduction: Operates at 82 dB(A) or less at blank-off, ensuring low mechanical noise during operation.

4. Slinger Seals:

• Non-Contacting Slinger Seals: In addition to the mechanical drive shaft seals, the vacuum boosters incorporate slinger seals on the rotor shafts. These non-contacting, non-wearing seals offer extra protection, reducing wear on the components.
• Water-Cooled Drive Shaft Seal: Ensures efficient cooling for long-lasting performance.
• Flanged Port Fittings: Standard for ease of installation and use in various applications.
• Cooling Coils: Not included with versions using slinger seals.

5. Special Materials (for specific models):

• Standard Construction Materials: The vacuum boosters feature cast iron housing, ductile iron rotors, and shafts for durability.
• Special Materials: For specific models, alternative materials such as stainless steel, carbon steel, and ductile iron can be used. Additionally, Bi-Protec® Nickel/Armoloy® special coating is available for enhanced protection.

6. Optional Motor Mounting Flanges:

• Direct Motor Mounting: All models are available with flange adapters for direct mounting of either a NEMA C-face motor (up to 75 HP) or an IEC D-flange motor (up to 55 kW). This eliminates the need for a separate base-mounted assembly and coupling guard, simplifying installation.

7. Metric Availability:

• Metric Connections: M-D Pneumatics vacuum boosters are available with metric drive shaft and process connections, offering flexibility for international applications.

8. Special Testing:

• The vacuum boosters undergo rigorous testing to ensure high quality:
  • ASME PTC-9 testing (1 PSIG slip method)
  • Hydrostatic testing up to 150 PSIG (10.35 bar g)
  • Pressure gas testing up to 100 PSIG (6.9 bar g)
  • Seal leakage testing to ensure reliable, leak-free operation.

• Chemicals & Petrochemicals: Enhance the performance of vacuum systems used in chemical processing, ensuring deeper vacuum levels and improved operational efficiency.
• Plastics & Semiconductors: Essential for precise vacuum environments required in plastics molding and semiconductor production.
• Food Processing: Helps to create controlled vacuum environments for food packaging and processing.
• Wood Composites & Vacuum Furnace: Improves the quality and speed of processes requiring high-vacuum systems.
