The SDP series dry screw vacuum pumps can be applied to a wide variety of vacuum processing applications across general industrial fields, such as drying and concentration processes in the chemical and pharmaceutical industries. In particular, during the reaction, extrusion, and distillation processes of synthetic resins, the SDP series products consistently deliver optimal performance.
Advantageous features
Perfect vacuum handling capacity: 100–800 m³/hr.
It doesn't use oil or water, so it won't cause oil or water pollution.
Low power consumption, low noise, low vibration, excellent dynamic balance, no inertial forces, and capable of high-speed operation.
The design features a simple structure, is easy to maintain, has low maintenance costs, contains no wear-and-tear parts, and boasts a long service life.
Wide range of applications and high vacuum performance.
Long service life; all gas-contact parts are corrosion-resistant and coated.
Lip-type sealing, not using mechanical seals, avoids frequent failures caused by contamination, and the bearings are highly durable.
Coating standard: Corrosion- and heat-resistant Hastelloy alloy

The application of dry screw pumps in semiconductor synthesis and liquid crystal production primarily involves processes such as plasma-enhanced chemical vapor deposition (PECVD) and reactive ion etching (RIE) for semiconductors, as well as the etching process in liquid crystal production and the CVD process used to manufacture TFT display plasma (PLASMA) panels. These processes require zero backflow to protect the workpieces from contamination.
The application of dry screw pumps in the petrochemical industry primarily involves extracting condensable gases, toxic gases, corrosive gases, or gases containing fine particulates.
In the pharmaceutical industry, it is used for vacuum drying of drugs, recovery of pharmaceutical intermediates, sterilization of recovered gas disinfectants, and providing clean, sterile conditions for artificial organs.
In chemical engineering, used for vacuum distillation and solvent extraction recovery—for example, processes such as the extraction and recovery of acetone, polyols, and other substances.
Industrial exhaust; centralized vacuum processing system
Mixing process of the extruder and degassing process for sheets
Mixed-resin deodorization process; used in fatty acid production to eliminate water pollution and remove blockages in ejectors.
All applications involving oil-free and water-free vacuum processing
The food industry uses it for flavorings, fragrance concentrates, and more.
