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. Small mechanical friction losses, so the drive power is small. Easy to maintain and repair, low cost, high life. Can be pumping condensable gases. ? Do not alone, you must configure before the pump. Hebei Roots pump prices are not allowed to start at atmospheric pressure, will be before the pump inlet pressure pumped Roots pump inlet pressure before the start time allows. Forepump for water ring pumps, reciprocating pumps, jet pumps, rotary vane pumps, claw pumps. Roots vacuum Main features:? High speed, high volumetric efficiency. ? Simple structure Hebei Roots vacuum supply prices, operation, and maintenance. ? Hebei Roots pump rotor is locked wholesale prices, without axial string action phenomenon. ? High-precision transmission gear and a good dynamic balance, low noise, smooth operation. ? Pump chamber for oil-free structure, applicable to the general air extraction and various special gases. ? Compared with other mechanical vacuum pump, energy-saving effect is remarkable. ? Before the pump can be used with all kinds of facilities, can be widely used in various processes range. ? Can be cooled and water-cooled to meet the requirements of different operating conditions.
