Titan Series
  Dekker’s Titan single-stage high-efficiency liquid ring vacuum pumps are capable of vacuum levels up to 29″   Hg. The pump features a variable discharge port design which adjusts automatically to the internal   compression ratio of the vacuum pump resulting in maximum efficiency throughout the vacuum range.   Advanced fluid dynamics result in high volumetric efficiency with 50% less seal-liquid requirement.

  DuraVane lubricated rotary vane vacuum pumps: single-stage pumps with an integrated oil-recirculation   system, used in a variety of industries such as vacuum packing, lifting, chucking, paper converting,   electronics, printing, biotech, laboratories and hospitals.
  DuraVane lubricated rotary vane vacuum pumps for saturated air (wet) service are specifically developed for   applications with high inlet water vapor content such as stone.

  HullVac rotary piston vacuum pumps are engineered for a long life, top performance, low maintenance and   ease of use. Dekker offers a comprehensive selection of models with valuable features and expert   aftermarket service, including a standard three-year warranty.

  The Maxima-C design is a robust design which features conical porting instead of flat plate porting offered on   the Maxima-K. The primary benefit of this design is its ability to handle more seal liquid or liquid carryover   through the suction compared to the flat plate design with less effect on power consumption and better   performance when handling saturated inlet gas.

  The Maxima-K design is a robust, single stage design which utilizes flat port plates mounted on each side of   the impeller. The variable discharge port allows the pump to operate efficiently throughout the vacuum range.   A heavy duty impeller features reinforcing rings to improve strength of the impeller blades and thus the   durability of the pump. Access plates on both sides of the pump allow for quick access to evaluate clearance   and perform boroscope inspection.
