    Claw dry vacuum pump is a kind of dry vacuum pump with variable-volume rotor for claw. Claw pump as an important member of the industrial vacuum pump family, although not widely talked about, but the characteristics and advantages of claw pump is very obvious. Today, we compare the claw pump with the traditional water ring vacuum pump to help you understand the claw vacuum pump.

 1.Comparison of corrosion resistance of equipment

    When there is acid gas in the pumping medium, because there is water in the water ring pump, acid gas is dissolved in water to form acid, which has corrosion effect on the pump body. Claw pumps are anhydrous, so there is no problem.

 2. the comparison of energy saving and emission reduction effects

    The water ring pump relies on the impeller to centrifugal the water, forming the liquid to gas compression, so as to achieve the pumping effect. Therefore, when the water ring vacuum pump works, it is mainly the energy consumption generated by the impeller to centrifugal the water, and the energy consumption remains at a high level in the whole working process. The claw pump adopts frequency conversion control, and the energy consumption is relatively constant in low vacuum. The main energy consumption of claw pump is the energy consumption consumed by the rotation of the pump itself. Compared with water ring pump, the energy consumption is lower.

 3.Comparison of vacuum stability

    With the increase of the system running time, the organic solvent content in the circulating liquid of water ring pump increases gradually, resulting in the decrease of the ultimate vacuum degree and the pumping rate of the vacuum unit. Claw vacuum pump because there is no water and oil, so this problem does not occur.

 4.sewage discharge comparison

    There is water in the water ring pump, sewage discharge is unavoidable, pollution to the environment, and treatment is difficult, high cost. Claw pumps have no sewage discharge.

 5. tail gas recovery comparison

    The tail gas of the water ring pump contains water produced in the process of operation, and the pure tail gas cannot be recovered. Claw pump can realize the recovery of pure tail gas. Especially for petroleum, pharmaceutical and other industries, will not produce sewage, waste gas pollution.

    Kelit claw vacuum pump has the characteristics of efficient pumping efficiency, super steam and particulate matter handling capacity, perfect matching process vacuum degree control, 100% cavity can be cleaned and so on. Widely used in: petrochemical industry, pharmaceutical industry, food industry, scientific research institutes, electronic photovoltaic, aerospace, metallurgical industry, etc. If need, welcome to inquire.
