Roots vacuum pumps is a rotating-pump,which should working with backing pump,it is not only can achieves  higher speed under lower inlet pressure ,but also can pump gas with dust and others ,the root pump is widely used in metallury,chemical ,industry ,food and papermaking industries.

Roos pump has reasonable structure, small size, high efficiency, low noise, smooth running, etc.

Roots pump

Key Features
    1, the product line using clover-type impeller, spiral structure

exhaust, exhaust pulse gently, less vibration and low noise.
    2, the product is a special curve to make the perfect engagement

effectively reduce leakage and improve efficiency.
    3, hardened by high-precision synchronous drive gear, imported

bearings, equipment, long life, low noise.
    4, high precision rotor dynamic balance, dynamic balance through

rigorous testing, high-speed operation of the force balance, low

vibration.
    5, transmission medium is not oil. No oil lubrication the internal

chassis, and used to avoid bearing, gear oil mixed with chassis

structural design. Output of air cleaning, dust does not contain any

oil.
    6, compact structure, small size and light weight.
    Third, standard accessories:
