Single-piece variable-pitch rotors deliver progressive internal compression, cutting power draw by 16.6%–23.8% and lowering exhaust gas thermal load during high-speed operation.
Customizable rotor and chamber coatings including PTFE, PFA, Hastelloy, Molybdenum, and Nano-Ceramics engineered in partnership with specialized materials manufacturers to withstand aggressive chemical vapors.
Advanced multi-layer sealing architecture with end-cover Nitrogen (N2) gas purge ports establishes positive pressure barriers to protect bearings against particulate and toxic vapor contamination.
Machined within 0.02 mm (20 microns) and double-treated for surface durability, allowing frictionless dry rotation and stable ultimate vacuum down to 0.8 Pa.
Handles organic solvent vapors, volatile acids, and heavy moisture streams from large-scale reaction vessels without oil emulsification or wastewater output.
Provides oil-free, hydrocarbon-clean vacuum environments required for wafer drying, plasma process exhaust, and thin-film coating systems.
Enables direct downstream condensation and clean solvent reclamation without producing contaminated oil or water waste.
Maintains continuous, high-flow rate pumping performance for industrial-scale batch dryers, vacuum concentration, and fine distillation units.
The ZDB11 delivers a pumping speed of 450 m³/h (125 L/s) with an 11 kW motor, while the ZDB15 provides 660 m³/h (183 L/s) with a 15 kW motor. Both models achieve an ultimate pressure of 0.8 Pa (0.008 mbar).
Variable-pitch screw rotors compress vapors multi-stage in a single molding design, cutting power consumption by 16.6% to 23.8% compared to constant-pitch pumps and significantly reducing operating temperatures during continuous operation.
Yes. The non-contact dry compression chamber handles heavy water vapor and small particulates. Internal rotors and casing surfaces can be factory-coated with PTFE, PFA, Hastelloy, Molybdenum, or Nano-Ceramics for aggressive chemical environments.
The pumps utilize a multi-layer sealing architecture paired with a pressurized Nitrogen (N2) barrier structure on the end covers, creating a positive pressure barrier that locks out process media and extends bearing life.
