Dekker’s Titan single-stage high-efficiency liquid ring vacuum pumps are capable of vacuum levels up to 29" Hg.
The pumps feature 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.
The Maxima-C is a robust design, which features conical porting instead of flat plate porting offered on the Maxima-K. The cones are attached to the end housing of the pump and protrude into the impeller on both sides. Air enters the impeller in a radial direction versus axially when compared to the flat plate design. 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-C features a shrouded rotor and heavy-duty cones and bearings. Packed gland sealing is standard with optional mechanical seals available. Other features include removable bearing brackets, multiple inlet/discharge port configurations and a casing partition allowing for different operating pressures at each inlet port. The Maxima-C pumps are available in capacities ranging from 700 to 22,000 ACFM, multiple material configurations and are manufactured to ISO 9001:2008 quality standards. Bolt in replacements are available for the NASHTM CL series, 904 series and AT series. Selection of Maxima-C versus Maxima-K depends on operating conditions and the most efficient operating point.
The Maxima-K 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. Packed gland sealing is standard, featuring a split ring gland for ease of maintenance; mechanical seals are optional. Access plates on both sides of the pump allow for quick access to evaluate clearance and perform boroscope inspection. The Maxima-K pumps are available in capacities ranging 1500 ACFM to 39,500 ACFM, are available in various materials/coatings and are manufactured to ISO 9001:2008 quality standards. Bolt in replacements are available for the NASH (or Siemens) 2BE series. Selection of Maxima-K versus Maxima-C depends on operating conditions and the most efficient operating point.
