The main features of Roots vacuum over a wide pressure range (1-1 × 10-4) has a higher pumping speed and pump chamber without oil, to avoid contamination of the oil vapor vacuum system. · Vibration, little noise. · Roots vacuum mechanical friction loss is small, so the drive power is small. Easy to maintain and repair costs low Hebei Roots pump manufacturers, wholesale, high life. Can be pumping condensable gases. ? Do not alone, you must configure before the pump. Only allowed to start at atmospheric pressure started to be before the pump will be able to get the Roots pump inlet pressure to allow the inlet pressure. Forepump for water ring pumps, reciprocating pumps, jet pumps, rotary vane pumps, claw pumps. ZJP series Roots vacuum pump is the perfect type of a structure volume Hebei Roots vacuum pump uses, it's biggest advantage is at lower inlet pressure with high pumping speed Hebei Roots pump prices, and can achieve a relatively high The 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, low maintenance costs. 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.
