■ Overview
The best ultimate pressure and completely oil free
SDP series dry screw vacuum pump is the one with a single stage direct connected structure. This series of products can be applied in all kinds of vacuum processing of general industries, such as drying and concentration in chemical and pharmaceuticals, especially in the reaction, extrusion, distillation of synthetic resin making. Since there is with pollution, SDP series performs its best.
■ Advantages and characteristics:
● Perfect vacuum treatment capacity: 100-800m3/h.
● No use of water or oil, causing no pollution.
● Low power consumption, low noise, low vibration, good dynamic balance, no inertial force, high speed operation.
● Simple design structure, easy maintenance, low maintenance costs, no wearing parts, long life
● Wide range of applications, with high vacuum performance.
● Long service life, parts that gas is in contact with are with cavitation proof and heat proof coatings.
● Lip type seals, no mechanical seals, sealing parts are without pollution, will not cause frequent failure due to pollution.
● Coating standards: cavitation proof and heat proof hastelloy。
■ Standard accessories:

The applications:
●The application in semiconductor synthesis and liquid crystal production mainly includes semiconductor plasma enhanced chemical vapor deposition (PECVD) and reflective ion etching (RIE) process, etching process in liquid crystal production and CVD process in TFT screen plasma production. This process requires a return of 0 to protect the work piece from contamination.
● In petrochemicals, it is mainly to suck condensable gases, or toxic gases, or corrosive gases, or gases containing micro-dust.
● In pharmaceutical industry, it is for the vacuum drying of drugs, for the recovery of drug intermediates and gas disinfectants, and to provide clean and sterile conditions for artificial organs.
● In chemicals, it is for vacuum distillation and solvent extraction recovery, such as extraction and recovery of acetone, polyols and other processes
● Industrial exhausting; Centralized vacuum processing system
● Mixing process of extruder and exhaust process of wood panel processing
● Deodorant process of mixed resins; To eliminate water pollution in the production of fatty acids and clear the stopper in the ejector
● For food industry, it is used for condensing of spices and flavors, food packaging and so on.
