The pump has only one moving part – a rotating impeller. Between the impeller and the casing machine, and end covers are guaranteed a gap, and because the machine does not have moving parts, no wear and tear caused by this. At the pump, no valves, pinion gears, etc. details, which also ensures high reliability. The machine has no oil pumps and special lubrication systems, all clearances between the impeller and the casing sealed working fluid, which lubricates the seals and seal rotor shaft. In the grease need only rotor bearings.
Pump parts manufacturer does not require high accuracy class, all the details in it are interchangeable. In the case of wear some end surfaces of the impeller as a result of years of work, if you have exhausted gas dust, sand and other impurities, restore the necessary clearances performed by selecting spacers between the housing and end covers. These features predetermine the low cost of the pump and ease of maintenance. The machine can operate autonomously for a long time.
Water ring Taco 007 pumps are among the few oil-free expansion pump. They do not require re-filtering the gas and not susceptible to falling into them, together with suction gas dust, water, sand and other impurities. All that remains in the liquid ring, and the car comes out clean gas. At the same time, the presence of a constant fluid motion does not allow particles deposited inside the shell of the car they are presented together with the outgoing fluid.
Hot water pump Taco 007-IFC provide a uniform suction and delivery of compressed gas. They may produce suction gas and simultaneously serve Him in a container with a pressure greater than atmospheric. One of the significant advantages of the pump is the isothermal compression process, which is needed in several industries: during compression of acetylene, carbon dioxide, chlorine and other gases.
If the gases in sucks a large amount of water vapor, then in contact with the liquid they are condensed in the car, resulting in increasing its productivity. The main disadvantage of liquid ring pumps is relatively low expansion. In the domestic liquid ring expansion pumps ultimate expansion with zero productivity is 90-95% (80-40 mm Hg). In some instances achieved a expansion of up to 20 mm Hg, but it is not stable. Two-stage pumps some foreign firms provide expansion up to 10 mm Hg
