Overview
The DP type oil-free screw vacuum pump does not require lubricating oil and sealing liquid in the working chamber, and can recover various condensable gases, solving the pollution problems that steam jet pumps, slide valve pumps, rotary vane pumps, liquid ring pumps, etc. may cause to the vacuum system and the environment. At the same time, the recovered materials can also create additional economic benefits.
Product Details
Price of DP type oil-free screw vacuum pumpProduct Overview
Dry screw vacuum pump is a pumping device that uses a pair of screw rotors with opposite rotation directions to perform synchronous high-speed meshing and rotational motion in the pump casing, producing suction and exhaust effects. The use of maintenance free design technology has solved the problems of difficult and expensive maintenance of vacuum pumps. The working chamber of the vacuum pump does not require lubricating oil and sealing liquid, and can recover various condensable gases, solving the pollution problems that may be caused to the vacuum system and the environment by steam jet pumps, slide valve pumps, rotary vane pumps, liquid ring pumps, etc. At the same time, the recovered materials can also create additional economic benefits.
Price of DP type oil-free screw vacuum pumpMain Features
Single stage design can achieve a high vacuum of 5Pa, and can operate continuously for a long time from atmospheric to ultimate vacuum.
Single stage design can easily discharge solid waste and remove residual materials inside the pump.
The screw material is integral ductile iron with high strength and good reliability.
There is no contact or friction between the screw rotors, and the speed is high and stable.
Low noise and vibration, suitable for quiet environments such as microelectronics and semiconductors.
The pump chamber is designed with an oil-free structure, with no exhaust gas or waste liquid discharge, making it particularly environmentally friendly and energy-saving.
Screw rotors and pump chambers with special coatings can extract condensable gases and toxic and harmful gases.
Internal parts can be treated with anti-corrosion coating, which can meet the special requirements of the chemical and pharmaceutical industry.
