 The spiral vacuum pump model provides pumping speeds up to 40 m3 / h. This makes the system very suitable for operations with inlet pressure between 1 mbar and 10 mbar, especially in ICPMS and LCMS, where pumping speed needs to be increased.

 
 
This model adopts advanced tip sealing technology, which can realize longer time before replacing the tip sealing. In addition, through the inverter drive control interface, users can remotely operate the pump while monitoring the motor's efficiency, speed and productivity.
 
spiral vacuum pump can achieve high vacuum. Seals do not contain any lubricant, seals or gear oil.
 
spiral vacuum pump. Ideal for cleaning and drying fine vacuum pumps. Due to screw technology, Fossa spiral vacuum pump can achieve high final vacuum and suction capacity at low power consumption. Seals do not contain any lubricant, seals or gear oil.

A method for analyzing the pumping performance of helical slot viscous vacuum pump with arbitrary groove cross-section is presented. Numerical calculations are performed on triangular and semicircular and rectangular grooves. Flow in the groove area is Boon and Tal's "narrow groove theory" that connects flows in the ridge area to gain pumping performance. If the optimal spiral Angle is selected, the zero flow performance of the three groove shapes is almost the same. The results show that compared with the traditional Holweck pump, the radial clearance can be increased by 20-100 times.
