ZJP series Roots vacuum pump is perfect for a positive displacement vacuum pump structure, its biggest advantage is a high pumping speed Hebei Roots vacuum where the best at low inlet pressure, and can achieve a relatively high ultimate vacuum . Since the pump is directly used as the main parts of the exhaust between the shaft housing, rotor and cap no relative movement contact, so stable ZJP series Roots vacuum pumps operating performance, long life Hebei Roots vacuum wholesale prices, maintenance costs small. The current vacuum pump is widely used for smelting, vacuum welding, vacuum casting, vacuum coating, vacuum dynamic tests and chemical and pharmaceutical, electric vacuum casting manufacturing various vacuum processing can be achieved within the vacuum pump range. ZJQ series of air-cooled Roots vacuum pumps, vacuum pump is the basis of ZJ series Roots adds bypass gas cooling system derived from the new products. Due to its special design Hebei where Roots vacuum, so that it can pressure differential and high compression ratio in the long-term reliable operation. ZJ series Roots vacuum pump is a rotary positive displacement pumps, must have before the pump is intended for use with the Roots vacuum, in a wide range of pressures greater pumping speed was pumping gas to contain dust and Water vapor is not sensitive, widely used in metallurgy, chemical industry, food, electronics and other industries coating.
