MD-Kinney Vacuum Boosters
Vacuum boosters used with all types of vacuum pumps. Utilized in the manufacture of chemicals, petrochemicals, plastics, food processing, and many other applications.
Vacuum boosters are used to “supercharge” vacuum pumps to greatly extend pump performance. This allows for much faster pumping speeds and deeper vacuum levels. MD-Kinney vacuum boosters are utilized worldwide in 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. They are available up to 10,000 CFM with a variety of different seals and lubrication options.
Mechanical Seals, Integral Pressure Lubrication
These series incorporate mechanical seals on the rotor shafts and the drive shaft, flanged port fittings, water cooled drive shaft seal, integral pressure lubrication system with water cooled heat exchanger, and cooling coils in the end covers. Water cooled drive shaft seal not included with optional motor mounting flange versions.
Slinger Seals, Integral Pressure Lubrication
These series utilize a mechanical drive shaft seal in conjunction with a non-contacting, non-wearing slinger seal on the rotor shafts, flanged port fittings, water cooled drive shaft seal, and integral pressure lubrication system with water cooled heat exchanger. Cooling coils are not included.
Mechanical Seals
These series incorporate 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.
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. Cooling coils are not included.
