► Cover direct cooling water technology
       Cover straight cold water Roots vacuum technology is advanced cooling technology. Its main feature is the built- in end cap through a combination of cooling water tank , the pump is directly absorbed by the internal heat of compression chamber Roots pump pumping exhaust generated in the pump chamber , blocking the heat pump to the front cover and transmission parts conduction, to minimize the temperature rise of the pump .
 
► Built-in pre- vent technology
       Low exhaust gas built-in technique using pre- accelerate the gas to the front and rear cover vent residual discharge pressure of the pump chamber and a rapid equilibrium between the front and rear differential cover , after elimination of the cap to the pump suction chamber residual gas permeation , shorten the time to pre- ; eliminate the front cover of the oil leak and contaminate the pump chamber was evacuated environment to ensure that the pump chamber and rotors dry and free of oil.
 
► cooled enhancement technology
       The outer surface of the pump increased the number of air-cooled fins , to maximize the cooling surface area, strengthen the RTO series Roots vacuum cooling effect , ensuring nowhere in particular water-cooled Roots pump conditions can still work, especially when Roots vacuum pumping speed is less than or equal 300L / s when the effect is more pronounced.
 
► gland and then moving technology
       Gland and then moving technology means that when the skeleton oil seal wear and tear , you can install the dislocation of the skeleton oil seal , oil seal skeleton became so wearing parts can be reused , to repeat the envelope on the skeleton oil recycling , to ensure the maintenance convenience , while further reducing the maintenance costs of the user.
 

► synchronous processing error compensation
       Intelligent CNC machining rotor technology, a unique 360 ° cutting tools , coupled with the company independently developed by the extraction Man synchronous processing error compensation software , completely eliminating the coordinates of the core components of the rotor machining process due to the rigidity of the machine and tool problems caused by loss accurate, drift phenomenon rotor profile , make sure the rotor machining accuracy and interchangeability.
 
► flexible assembly and disassembly and positioning technologies
       Assembly and disassembly of the entire process used to avoid the impact of a flexible assembly and disassembly techniques avoid the disassembly of the pump due to the rotating member , in particular damage to the precision bearing ; shaft and gear , are zero clearance between the shaft and the coupling , since centering, easy assembly and disassembly flexible positioning technology to ensure the smooth running of the accuracy , quiet and power transmission .
