    Product Applications
    Slide valve vacuum pump is the oil seal variable mechanical pump, which is the ideal vacuum equipment pumping particular gas or condensable gas (gas ballast device) in sealed container. It can be obtained negative pressure directly, or obtained higher vacuum as the other vacuum system’s backing pump. Because of the non-contact rolling motion between the slide valve and the pump chamber, so the pump has the characteristics of dirt-resistant, corrosion preventive and durable. The bearing of the pump are lubricated by grease, which is separated from the pump oil, can be used to pumping the gas with a small amount of dust. In currently, the pump has been widely used in metallurgical, chemical, pharmaceutical, textile, semiconductor, silicon, polycrystalline silicon, petroleum, food and nuclear energy and other fields.
