• It can also be applicable as the pre – pump of various types of high vacuum
equipment.
High vacuum, high pump speed
Two stage rotary – vane design improves the ultimate vacuum and pump speed
and reduces the evacuation time.
Oil pump cycling system design
Built – in oil pump cycling design forced – lubricates the pump chamber and
sliding bearing and ensures its lubrication and seal. Besides, big sight glass and
low oil level design avoids running without oil and ensures reliable usage.
