Features of Screw type Dry Vacuum Pumps

• Oil & Water free Dry running operation makes clean vacuum
• Single stage design enables solid waste easy discharge and eliminate residue in the pump
• Suitable for pumping Toxic, Corrosive and condensable gas by special coating
• Not using Oil or Water as pumping medium, low operation cost.
• Bellows type Mech, seals or Lip Seal
• Simple design results easy maintenance
• No metal-metal contact between Screw and Casing ensures long pump
• Short gas path through the pump make quick gas discharge
• Screw type rotors have high volume efficiency
• Slow rotational speed results low vibration and low noise level

Screw Rotor & Single Stage

• Higher Volume Etticiency
• Higher Compression Ratio
• Improve Pumping Speed
• Lower Cost of Ownership

Characteristics of C-flange Products

For simplicity and space saving, model P250 are available with flanged adaptors for mounting. Various standards C-face motor directly to the Vacuum pumps, eliminating the need for a separate for the vacuum pumps. Base frame mounted assembly and coupling guard. The other model(P-400, P800)are manufactured for special

Advantages of C-flange models are

• Reduced installation space
• Simplified mounting
• Reduced noise level
• No alignment required
