Vacuum boosters are used to “supercharge” vacuum pumps to greatly extend pump performance. This creates faster pumping speeds and deeper vacuum levels.
M-D Pneumatics vacuum boosters are utilized worldwide in the toughest applications including: the manufacture of chemicals, petrochemicals, plastics, semiconductors and wood composites as well as food processing, vacuum furnace applications and many other general applications in industry.
Low Mechanical Noise: Every M-D Pneumatics vacuum booster is designed to operate at 82 dB(A) or less at blank-off (open field; motor and background noise excluded).
Mechanical Seals: This series incorporates mechanical sealing on the rotor shafts and the drive shaft, flanged port fittings, water-cooled drive shaft seal, and cooling coils in the end covers (not included with optional motor mounting flange versions).
Slinger Seals: These series utilize a mechanical drive shaft seal in conjunction with a non-contacting, non-wearing slinger seal on the rotor shafts, water-cooled drive shaft seal, flanged port fittings, and are dependable performers for air and many gas applications.
Special Materials: Standard construction materials include cast iron housing, end plates, end covers with port fittings, and ductile iron rotors and shafts, while special materials available (limited models) include stainless steel, carbon steel, or ductile iron models. Bi-Protec® is available as a Nickel/Armoloy® special coating.
Optional Motor Mounting Flanges: All models are available with flange adapters for mounting either a NEMA C-face motor (up to 75 HP) or an IEC D-flange motor (up to 55 kW) directly to the vacuum booster, eliminating the need for a separate base mounted assembly and coupling guard for the vacuum booster.
Metric Availability: All M-D PneumaticsTM vacuum boosters are available with metric drive shaft and process connections.
Special Testing: 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), and seal leakage testing
