  • The anatomy of a large hydraulic power system
    Large hydraulic-system basics, shock-absorber lessons, air-hydraulic pumps, and more are included in this hydraulics reference guide. The Lifco power unit, built for an 800-ton upstroking press, uses Denison valves and pumps. The design and construction of a large central hydraulic system involves
  • Vacuum pumps
    In principle, industrial vacuum pumps are merely compressors run with the inlet attached to the vacuum system and the outlet open to exhaust. In smaller sizes, compressors and vacuum pumps are often identical machines. However, in the large sizes that might power a plant-wide vacuum system

  • The Case for Dedicated Laboratory Vacuum Systems
    The demand for a reliable vacuum source has led to several different vacuum pump solutions. Many large industrial and academic labs traditionally use a centrally located house vacuum system. House vacuums normally consist of a large, powerful vacuum pump designed to distribute vacuum throughout

  • Vacuum Requirements for Steel Degassing (.pdf)
    Vacuum degassing (VD) and vacuum oxygen decarburisation (VOD) are the main processes in secondary steel making. The large volumes of dissolved contaminant gases arising and the generation of metallic fines and oxide dust require robust, high-capacity pumping equipment. Today's advanced vacuum dry
