Water-sealed vacuum pump SW series

Shinko Seiki's water-sealed vacuum pump that accommodates the exhaust of all gases.

This is a standard model with a rich sales record. It stably exhausts various gases that can cause troubles in other systems by sealing them with water. ◆ The water-sealed vacuum pump allows for the exhaust of condensable and flammable gases by sealing with water. ◆ Due to its water-sealed design, it has high discharge capability and is not easily stopped by minor dust. ◆ For applications where corrosive gases may be present, it is possible to select materials with excellent corrosion resistance, such as stainless steel. ◆ Being a two-stage model, it achieves an excellent ultimate pressure of 2,300 Pa (at a water temperature of 15°C). Additionally, when combined with an air ejector, it can be improved to between 800 and 1,300 Pa. ◆ The shaft sealing part comes standard with gland packing, but mechanical seals can also be selected. ◆ It is equipped with a standard gas-water separation tank that also serves as a silencer. ◆ To prevent harmful gases from dissolving in the sealing water and being discharged, we also offer a "sealed liquid circulation type" water-sealed vacuum pump that circulates the sealing water without direct outflow.
