Wordfk PSV series two-stage oil-lubricated vacuum pumps achieve higher vacuum and better performancethrough a two-stage series pumping structure. Gas enters the first-stage pump chamber through the air inlet, andthe rotor rotates to drive the vanes to compress the gas and discharge it to the second-stage pump chamber, whereit is further compressed to reduce the pressure to the high vacuum range. Higher ultimate vacuum can meet thespecial vacuum requirements of industries such as precision manufacturing and scientific research.
The innovative circulating oil supply system of the PsV series two-stage pump makes the industrial pump morestable and reduces the maintenance cost. The automatic anti-backflow oil valve and two-position adjustable airfoat ensure the reliability of the industrial pump. Due to their quiet operation, they are perfectly suited forapplications where alow noise level is essential.
Features:
• Stable and Low Noise Operation
• Corrosion-Resistant Version Available
• Excellent Performance
• Double Anti-oil Structure
• Excellent Heat Dissipation
• High Quality Oil Mist Filtration
