Roots Vacuum Pump Price

The great advantage of Roots vacuum pump is that it has a higher pumping rate at lower inlet pressure, but it can not be used alone. It must have a front vacuum pump in series. When the pressure in the pumped system is pumped to the admissible inlet pressure of Roots vacuum pump, Roots vacuum pump can start to work. In general, Roots vacuum pump does not allow high differential pressure to work. Otherwise, it will be overloaded and overheated and damaged, so the use of Roots vacuum pump must reasonably select the front vacuum pump, install the necessary protection equipment.claw-vacuum-pump

Generally, oil seal mechanical pump or liquid ring vacuum pump can be chosen for the front stage vacuum pump. Especially when a large amount of vapor is pumped out, it is ideal to choose water ring vacuum pump as the front stage pump.
The characteristics of Roots vacuum pump are described as follows:

1. There is a certain gap between the rotor and the pump chamber, between the rotor and the rotor, which is not in contact with each other and does not need oil lubrication.

2. The rotor has good geometric symmetry, which can improve the speed, so that it can produce large pumps with compact structure.

3. Vacuum pump has small vibration and large volume, and its volume utilization coefficient is about 0 and 5.water-ring-vacuum-pumps

4. There is no compression phenomenon like mechanical vacuum pump in the pump chamber, so it does not need exhaust valve. It is also for this reason that condensable steam can be removed.

5. Quick start-up, can reach the limit vacuum in a short time. Low power, low operation and maintenance costs.vacuum-pump-in-freeze-drying-process

6. Roots pump has a large pumping speed in a wide pressure range (1000-1Pa), which can rapidly discharge the sudden gas, making up for the defect that the pumping speed of diffusion pump and oil seal mechanical pump is very small at 1000Pa-1Pa. Therefore, it is suitable for supercharged pumps.vacuum-pumps-application

Roots Vacuum Pump is a kind of variable-volume rotary vacuum pump, which can be used only with the cooperation of the front pump. It has a larger pumping speed in a wide pressure range and is insensitive to dust and water vapor in the extracted gas. It is widely used in metallurgy, chemical industry, food, electronics, coating and other industries.
