Overview:
Dry screw vacuum pump, which utilizes a pair of screw rotors rotating in opposite directions to synchronize and rotate at high speed within the pump housing, creating suction and exhaust functions for gas evacuation. The maintenance-free design technology solves the issues of high maintenance trouble and costs for vacuum pumps. The working chamber of the vacuum pump does not require lubricating oil or sealing fluid, allowing for the recovery of various condensable gases. This resolves potential contamination issues to the vacuum system from steam jet pumps, slide valve pumps, scroll pumps, and liquid ring pumps, as well as environmental pollution. Moreover, the recovered materials can also generate additional economic benefits.

Product Images:
Achieve high vacuum in solvent environments or under slight acidic or alkaline corrosion conditions, with a vacuum level up to 5 Pa. Free from water and oil contamination, ideal for obtaining clean gases.
Model and Technical Specifications:
Product Highlights:
1. Compared to equal-pitch screw pump, it offers higher vacuum extraction efficiency and lower energy consumption.
2. Wide flow rate range, capable of direct discharge into the atmosphere; a single pump can achieve multi-stage serial effects. A single-stage design can achieve a vacuum of 5 Pa.
3. Nitrogen blow cleaning is available, with simple cleaning and maintenance operations, and easy repair.
4. The screw material is solid ductile iron casting, featuring high strength and stable performance.
5. The screws do not touch each other, eliminating friction, and do not require lubricating oil. There is no oil spillage or waste gas排放, ensuring a clean and environmentally friendly operation with low energy consumption.
6. The pump cavity and components can be surface anti-corrosion treated as required, suitable for the special requirements of the chemical and pharmaceutical industry.
7. The screw has been precisely balanced for dynamic operation, ensuring smooth running, low noise, minimal vibration, and an extended service life.
