Dry screw vacuum pump (VDP-V Series)

VDP-V model is the latest model that applies a continuous variable screw rotor machined integrally and improves overall performance efficiency through increased operational stability and 30% reduction in power energy compared to the existing models with the same capacity in addition to the advantages of the constant pitch screw. The advanced integral-type variable screw rotor mechanism ensures performance improvement and helps to maintain gas flow path and compression process more quickly and reliably, thereby improving operational stability and durability. The continuous variable screw rotor design with screw design with a new format boasts more improved capacity to emit water vapor, liquid and power compared to the existing products, and it enables more stable operation with low-noise and low-vibration.

Features and Benefits

01 Excellent durability
  • Improved operational stability due to application of integral-type variable screw
  • Superior mechanical durability due to the non-contact operation between the screw and cylinder inside the pump
02Echo friendly & economical operation
  • Economical and eco-friendly dry operation without using water and oil
  • Energy savings increased by 30% compared to conventional pitch screw
03 Various corrosion resistant coating

Possible to apply various special coating inside the pump to prevent corrosion caused by process by-products

04Excellent discharge capacity

Excellent discharge capacity even in harsh process environment due to variable screw design of a sing structure with continuity

05 Operational stability
  • Excellent operational stability and durability due to low-noise and low-vibration operation by precision machining and balancing
  • Improved operational stability and durability resulting from low operational temperature reduced by more than 100 °C compared to existing products due to the increased compression efficiency of integral-type variable pitch screw

06 Flange-type motor with IEC standards

Accurate and easy to assemble due to application of flange-type motor with IEC standards and reduction in vibration due to optimal alignment assembling by machining tolerances


07 A variety of optional features

Possible to apply flushing, purging and control system options according to the process characteristics

08 Easy maintenance

Easy maintenance and cost savings due to simple structures by optimal design
