ZJP series roots vacuum pump with overflow valve (referred to as the roots pump hereinafter) are positive displacement pumps with two symmetrically shaped impellers, shaped like the figure “8”, rotate in opposite directions inside the pump housing. Roots pump are generally used to increase the pumping speed and/or to reach a higher end-vacuum on the pump system. Roots pumps are able to run at high rotation speed, as high as 1500~3000rpm, as the impellors are rotating non-contact. Due to the high rotation speed it is possible to have a high pumping speed with a relative small sized pump. It is possible to pump high quantities of gas in combination with a relative small backing pump. The energy consumption of such a system is much lower than of a single backing pump with the same pumping speed. The by-pass valve is mounted between the inlet and the exhaust and controls the pressure difference by opening and closing the by-pass valve by gravity. When the pressure difference between the inlet and exhaust is too high the by-pass valve will open and protects the Roots pump from overheating. This way it is possible to run the Roots pump at the same time that the backing pump starts and achieving the maximum pumping speed, also at higher pressures. There are two kinds of vacuum pumps, corrosion and anti-corrosion. The anti-corrosion roots vacuum pump is coated with Teflon or Ni-p by customer’s request. Also clients can choose skeleton oil seal or five point type oil seal by there own will.

Roots vacuum pump (referred to as: roots pump) refers to the pump is equipped with two opposite direction synchronous rotation of the leaf rotor, the rotor, the rotor and the pump shell wall has a small gap between the non-contact with a variable capacity vacuum pump. Roots vacuum pump animation: Application of roots vacuum pump : Roots vacuum pump, widely used in petroleum, chemical, plastics, pesticides, steam turbine rotor balancing, aerospace space simulation devices such as petroleum, chemical, metallurgy, textile and other industries.The accessories for the vacuum pump is vavuum pump muffler , which can deal with the noise. Structural features of roots vacuum pump: (1)within a wide range of pressure has a larger pumping speed; (2) the rotor has good geometric symmetry, so the vibration is small, smooth operation.There are gaps between the rotor and the rotor and the shell, it needs no lubrication, friction loss is small, can greatly reduce the drive power, which can achieve a higher turn Speed; (3) the pump cavity without oil seal and lubrication, it can reduce the oil vapor, which will pollut the vacuum system; (4) pump cavity without compression, no exhaust valve. The structure is simple, compact, Characteristics of roots vacuum pump 1.Start fast, 2.Less power consumption, 3.Low operation and maintenance costs, 4.Pumping speed, high efficiency

Product Description Roots vacuum pump is a dry positive displacement pump. They operate on the Roots principle, which is similar to that of rotary vane pumps. These pumps are the ideal solution when fast pumping speeds are required. In the case of contactless, oil-free compression Roots booster pumps, two symmetrical cams rotate in the working chamber. During this process, the rotating blades do not come into contact with each other or the housing. Roots vacuum pumps are often used in pumping stations in combination with oil-lubricated rotary vane pumps to achieve very high volume flows and deep final vacuums. Benyuan's three-lobes roots vacuum pump is an internationally advanced roots blower produced by importing and digesting patents and proprietary technology from the American Hibar company and utilizing the company's advanced manufacturing processes. Features 1. Air cooling. Pressure rises to -50 kpa 2. Small size, lightweight, dual-purpose for both vertical and horizontal use, convenient to replace European and American models 3. High-speed, energy-saving 4. Belt self-tensioning technology, easy to use and maintain 5.Impedance-integrated composite muffler with good noise reduction effect

Vacuum pump improved by raising the intensity in order to prevent cent rotor and axis deviation from external influences. Features: 1. Lower noise:pressure pluses are the major noise source in blowers. The trundean roots blower design can efficiently reduce noise by approximately 5 db. 2. Lower energy consumption:trundean roots blower are designed to control backflow pressure to the rotor in order to reduce energy consumption. 3. Longer bearing life:less vibration transmitted through the lobe results approximately 20% longer bearing life. -
