MOUNTING DIMENSIONS

LGB series Dry Screw Vacuum Pump

 

ADVANTAGES

Ultimate Vacuum

The perfect interstice design and continuous compression method, the ultimate vacuum of single pump can reach 0.0075Torr(0.01hpa).

 

Corrosion Resistance

1. Use the coating material with strong corrosion resistance

2. Through the gas ballast valve gear to reduce partial pressure of corrosive gas, prevent the corrosive gas condensation in the pump cavity, further improve the corrosion resistance ability

 

Cooling Effect

1. Using the spiral cooling water plug which conforms to fluid dynamics, heat transfer efficiency is good

2. Inside the pump to maintain reasonable low temperature, so the coating damage is very low

 

Energy Saving

1. Varying pitch screw energy-saving design, can reduce the power consumption of 30%

2. No need to supply the cooling gas to the interior of the pump

 

CHARACTERISTICS

Reliable Seal Structure

1. Lip seal and mechanical seal, and gas sealing, form a triple seal structure

2. Installation of high-performance mechanical seal designed for dry vacuum pump

3. Excellent appropriate pressurization gas sealing device, further improves the sealing between the gear oil and process gases pumped.

 

Smooth Discharge Structure

1. Quickly exhaust structure

2. Good Liquid handling capacity

3. Reduce the discharge gas pulse

 

The Installation of gas ballast valve

1. To prevent the corrosive gas condensation

2. Reduce the partial pressure of explosive gas

 

Gear Oil Cooling Water Plug

1. Keep low oil temperature

2. Prevent gear oil oil leakage caused by high temperature and high pressure

3. To prevent the gear oil performance degradation due to high temperature
