2SK series Dual-stages Water Ring Vacuum
Pumps
and 2SK-P1 series Vacuum Pumps with Ejector
The 2SK
type dual-stages water ring vacuum pump is equal to putting two sets
of the SK type water ring vacuum pumps in series.
The limited vacuum of the SK series water ring vacuum pumps just reach
-700mmHg. In order to obtain larger suction capacity under the higher
vacuum, the 2SK series vacuum pumps are invented and produced in 1980s'domestic.
Accompanying with the new products of the 2BV and 2BE1 series vacuum
pumps with higher efficiency and economical power, the 2SK series pumps
will be replaced by them gradually.
The 2SK-P1 dual-stages water ring vacuum pump with an ejector mainly
works under the absolute pressure from 10 to 50mmHg. But its efficiency
is lower in the high vacuum scope. If the pump needs to work in the
high vacuum scope for a long time, it is better to choose the JZJ
series package unit for achieving the best suction capacity.
2SK series dual-stages water ring vacuum pump
Main Characteristics
- Comparing with the single stage water ring vacuum pump, it has the advantages of the higher vacuum and larger suction capacity in the high vacuum scope.
- Under the same suction capacity, its shaft power is obviously much higher than the 2BV and 2BE1 series pumps.
- The application scope is extensive and it can pump the gases that contain water or humid steam and a small amount dust or solid granules, even the flammable and explosive gas.
- The manufacture and maintenance are complicated for its dual impellers structure. And there are many easy worn parts of the pump.
