 DRF Series Roots Vacuum Pump

Advantage
DRF Roots Vacuum Pump is a well-developed vacuum pump equipment, which is helpful to expand the working range of vacuum pump under low inlet pressure after combining with the front vacuum pump:
1. Improve the vacuum.
If equipped with Roots vacuum pump, the system vacuum can be increased by an order of magnitude. The performance of the two-stage Roots vacuum pump may be higher.
2. Increase pumping speed.
When rotating in high speed mode, a pair of Roots pump rotors will not contact each other, which means that small Roots pump can also have high pumping speed. By choosing a suitable Roots pump, the front vacuum pump can pump large capacity air at low speed. Compared with the single-speed front vacuum pump, it can significantly reduce energy consumption.
Three
Oil-free rootless pump room without oil pollution, pumping medium without pollution.
4. Superior character.
DRF series Roots vacuum pump adopts flexible hydraulic device - an efficient power transmission mode. The transmission system has compact structure and superior performance. It has the following characteristics:
1). In the case of reducing the installation of bypass pipelines and valves or stopping the design of inverters, vacuum pumps can achieve better pumping effect than traditional booster pumps, which greatly saves the cost of hardware production and reduces the control requirements.
2). Hydraulic transmission device can automatically adjust the pumping speed, even if the pump works under high pressure, the motor will not overload or overheat.
3). Compared with the traditional direct drive, Roots vacuum pump will not be damaged even when the foreign body inlet pressure changes suddenly or ambitiously, and the stop failure rate can be greatly reduced.
4). Under normal pressure, DRF Roots vacuum pump can start the pre-vacuum pump at the same time, but the motor will not overload, it can work in the pre-pumping process, shorten the pumping time, especially suitable for the application occasions needed. Used for fast pumping.
5). It runs very smoothly and vibrates very slightly.
6). Reliable bearing seal structure ensures no lubricant in pump chamber.
7). No bypass and valve, easy maintenance.
