AquaSeal® DEKKER AquaSeal® water-sealed liquid ring vacuum pump systems are designed to customer requirements for each application as full seal-liquid (in this case water) recovery systems or as partial or no seal-liquid recovery systems.
AquaSealPOWERGEN® : AquaSealPOWERGEN® condenser-exhauster systems designed by Dekker Vacuum Technologies, Inc. are full-recovery two-stage liquid ring vacuum pump packages, using water as the seal-liquid. The systems are particularly well-suited by taking advantage of the high condensing effect, which drastically reduces the water vapor content resulting in a lower inlet volume to the pump.
ChemSeal®: DEKKER ChemSeal® solvent-sealed liquid ring vacuum pump systems are designed to customer requirements for each application, as full seal-liquid recovery systems for recovery of a variety of solvents.
DuratexTM: DuratexTM is a custom-formulated lubricant specifically designed for long life under the severe, demanding conditions usually encountered in recirculating systems such as rotary vane vacuum pumps and systems. They have a very low vapor pressure, making it an excellent lubricant for vacuum applications. Duratex lubricant is available in Standard and Synthetic in 32, 68 and 100 CS viscosities. DEKKER offers a comprehensive range of rotary vane vacuum pumps: lubricated pumps, lubricated pumps for saturated air (wet) service and oil-free (dry) rotary vane vacuum pumps. All pumps are of heavy-duty construction, compact design, and easy to install and low maintenance. Pumps are direct driven, air-cooled, and have a low noise level and long vane life.
DuraVane®: The DuraVane® rotary vane vacuum pump systems designed by Dekker Vacuum Technologies, Inc. are available in simplex and multiplex configurations, as stack-mounted, base-mounted or tank-mounted units. Systems can utilize lubricated or dry (oil-free) rotary vane vacuum pumps, are used in standard industrial applications and can be built to NFPA99 specifications for hospitals and laboratories.
DX-5:The DEKKER patented DX-5 and DX-7 air/oil separator design features five stages of separation resulting in the best air/oil separation in the industry. Another advantage of the DX-5 and DX-7 separators is the structural design. The tank is cylindrical, resulting in superior strength which is very important on units operating with back pressure. This design also eliminates possible leaks associated with square tank designs.
DX-7:The DEKKER patented DX-5 and DX-7 air/oil separator design features five stages of separation resulting in the best air/oil separation in the industry. Another advantage of the DX-5 and DX-7 separators is the structural design. The tank is cylindrical, resulting in superior strength which is very important on units operating with back pressure. This design also eliminates possible leaks associated with square tank designs.
HMI: Human-Machine Interface (HMI) is a user interface or dashboard that connects a person to a machine, system, or device.
HullVacTM: HullVac Rotary Piston Vacuum Pumps and Systems are engineered for a long life, top performance, low maintenance and ease of use. Available in single-stage with capacities up to 1280 CFM and two-stage with capacities up to 950 CFM. No center wall bearing means that the bearing will not be exposed to the pump oil which could be contaminated leading to reduced bearing life. Cage hinge Bars are in line thereby reducing wear. Improved exhaust valve design prohibits the possibility of worn valve components getting into the pumping chamber, which could result in major repairs. Robust Valve Wear Plates are hardened steel and provide longer life compared to plastic used by the competition. Improved O-Ring Sealing features an efficient design that reduces maintenance time and prevents leakage. The bottom of the valve deck contains and O-ring seal that is easy to replace. Other designs use paper seals which are inferior and disintegrate causing plugging
Liquid Ring Compressor: Dekker Vacuum Technologies, Inc. offers TiTAN® series high-efficiency single-stage liquid ring compressors as monoblock and bare shaft/pedestal models, covering a capacity range from 15 - 1,100 CFM (3 – 150 HP) with maximum pressure capabilities up to 29 psig. Stainless steel impellers are standard in compressors up to 20 HP. All models are designed for heavy-duty applications, are manufactured to ISO 9001 standards and feature mechanical shaft seals as standard. All compressors have only one moving part, low operating noise levels (68 – 80 dBA) and low maintenance. The biggest advantage of liquid ring compressors is that they can handle saturated gas mixtures and small amounts of liquid without damaging the internal parts of the compressor. All models are available in a variety of materials. Dekker Vacuum Technologies, Inc. offers large-capacity Maxima-K series single-stage liquid ring vacuum pumps in capacities ranging from 1,500 – 39,000 CFM (60 – 2,000 HP) with vacuum capabilities up to 29”. The advantage of the liquid ring design is the ability to handle large amounts of condensables. The condensing effect increases the actual pump capacity dramatically when handling saturated gas mixtures.
Maxima-CTM: The Maxima-CTM design is a robust design which features conical porting instead of flat plate porting offered on the Maxima-KTM. 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 20 blade 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 CLTM series, 904TM series and ATTM series. Selection of Maxima-C versus Maxima-K depends on operating conditions and the most efficient operating point.
Maxima-KTM: The Maxima-KTM 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. 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 multiple configurations and are manufactured to ISO 9001:2008 quality standards. Bolt in replacements are available for the NASHTM (or Siemens) 2BE series. Selection of Maxima-K versus Maxima-C depends on operating conditions and the most efficient operating point.
