Wordfik DVE series screw pump is an environmentally friendly, energy-saving, oil-free vacuum equipment. Wordfik provides vacuum pump models made of corrosion-resistant materials such as titanium steel and duplex steel to cope with harsh working environments such as toxic gases and corrosive gases.
The DVE series uses twin-screw precision meshing technology to achieve efficient gas compression and transportation through high-speed synchronous reverse rotation. The screw is dynamically balanced and calibrated, with a nano-level gap design, and operates without metal friction throughout the process, and will not generate high temperatures.
Wordfik provides a wide range of pumping rate models from 110m³/h to 1800m³/h to meet the needs of different industries. It is widely used in vacuum metallurgy, vacuum coating, vacuum drying, vacuum distillation, vacuum degassing and other industries.
