Product Description

Summarize:

ZJP Mechanical Roots Vacuum Pump (referred to as: Roots pump) refers to a variable-capacity vacuum pump in which there are two blade-shaped rotors that rotate synchronously in opposite directions, and there are small gaps between the rotors, the rotor and the inner wall of the pump casing without contacting each other.

Generally Used In:

Mechanical Booster Roots Vacuum Pumps are widely used in smelting, degassing and rolling in vacuum metallurgy, as well as vacuum distillation, vacuum concentration and vacuum drying in chemical, food, and pharmaceutical industries.

Advantage:

1. Larger pumping speed in a wide pressure range;
2. Start fast and work immediately;
3. Insensitive to dust and water vapor contained in the pumped gas;
4. The rotor does not need to be lubricated and there is no oil in the pump cavity;
5. The vibration is small, the rotor dynamic balance condition is better, and there is no exhaust valve;
6. The driving power is small, and the mechanical friction loss is small;
7. Compact structure, small footprint;
8. Operation and maintenance costs are low.
