Feature
(1)There is no touch between rotors, no need of oil lubrication.
(2)Rotor has a good geometric symmetry, non-friction, low power consumption, smooth running, low noise, faster speed direct drive, small size, light weight, and large pumping speed.
(3)There is no compressor phenomena like the vacuum pump in the pump cavity, therefore, no needs of exhaust valve and extract condensable vapour.
(4)It can reach to ultimate vacuum in short time and low-cost.
(5)The pump install valve on side to make sure its’ safe and reliable operation.
(6)The pump have a high speed in the pressure range(1.3×1000~1.3pa),can exhaust gas fast, which make up for the fault that diffusion pump and oil seal pump with low speed in the pressure range(1.3×1000~1.3pa). This kind of pump is widely used to vacuum degassing refining in metallurgical industry、 vacuum treatment of molten steel and heat treatment, etc, Food, Medicine, Motor manufacture industry, especially point out when the packing pump as two-stage liquid ring vacuum pump, it can extract the gas with a lot of steam, therefore, it suit to Distillation, evaporation, freezing,
drying process……
The type of this pump have : ZJP-30、ZJP-70、ZJP-150、ZJP-300、ZJP-600、ZJP-1200.
ZJP-Roots booster pump (P means it have valve on side)
30/70/150/300/600/1200-means main pump speed are 30/70/150/300/600/1200L/S.
