Vacuum Booster Models:

• Available in models 1800, 2200, 2900, 3600, and 4500, each offering progressively higher vacuum performance.

Mechanical Seals:

• These units use mechanical seals on both the rotor shafts and the drive shaft for enhanced sealing and durability.
• They come with flanged port fittings, water-cooled drive shaft seals, and cooling coils in the end covers.
• Optional motor mounting flanges are available in specific models.

Low Mechanical Noise:

• Designed to operate at or below 82 dB(A) at blank-off, ensuring minimal noise disruption in the workspace.

Slinger Seals:

• Uses mechanical drive shaft seals with a non-contacting slinger seal on the rotor shafts. These seals do not wear and are highly dependable, particularly for air and gas applications.

Construction Materials:

• Standard materials include cast iron for the housing, end plates, and end covers, and ductile iron for the rotors and shafts.
• Special materials like stainless steel, carbon steel, or additional coatings (e.g., Bi-Protec®) are available for certain models.

Motor Mounting Flanges:

• The units can be equipped with flange adapters for mounting NEMA C-face motors (up to 75 HP) or IEC D-flange motors (up to 55 kW). This eliminates the need for separate base-mounted assemblies or coupling guards.

Testing & Certifications:

• The vacuum boosters are tested to stringent standards, including:
  • ASME PTC-9 (1 PSIG slip method)
  • Hydrostatic testing to 150 PSIG (10.35 bar g)
  • Pressure gas testing to 100 PSIG (6.9 bar g)
  • Seal leakage testing.

Special Materials & Coatings:

• The option to apply special coatings such as Bi-Protec® (Nickel/Armoloy®) for corrosion resistance and enhanced performance.

Metric Availability:

• The vacuum boosters are available with metric drive shaft and process connections for international compatibility.
