and 2SK-P1 series Vacuum Pumps with Ejector
The 2SK type dual-stages water ring vacuum pump is equivalent to two
sets the SK type water ring vacuum pumps in series.
Because the limited vacuum of the SK series water ring vacuum pumps
just reach -700mmHg, in order to obtain bigger suction capacity under
the higher vacuum, the 2SK series vacuum pumps are developed and produced
in 1980s'domestic.
Accompanying 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 step by step.
The 2SK－P1 dual-stages water ring vacuum pump with ejector mainly works
under the absolute pressure from10 to 50mmHg. But its efficiency is
lower in the high vacuum scope. If the pump need to work in the high
vacuum scope for a long time, it is better to choose the
Roots pump and water ring vacuum pump 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 higher than the 2BV and 2BE1 series pumps.
- The application scope is extensively, and it can pump the gases that containing water or humid steam and a small amount dust or solid granules, even the flammable and explosive gas.
- The manufacture, maintenance are complicated for its dual impellers structure. And the easy worn parts are more.
