This type equips automatic
air vent mechanism. An air vent valve built-in pump chamber enables
reliable air venting. Also equipped manual air vent valve enables
easy pressure release in discharge piping. Gaseous liquid such as
sodium hypochlorite or hydrogen peroxide can be injected without gas
locking.
- Entrained air is automatically expelled from the pump head. No special degassing is needed.
- The pump immediately resumes operation without gas lock even after a long period of stoppage.
- Use the air vent port manually for quick release of discharge line pressure.
- Capable of pumping concentrated sodium hypochlorite

Principle of operation
Air which comes from suction port goes to the connection adapter through pump head. Because pump discharge side is pressurized, air goes to the automatic air vent valve which the pressure load is lower than pump discharge side, and goes out little by little together with liquid.
Once the pump gets out of locked air condition, it returns to normal operation to discharge the liquid. A ittle bit of liquid is discharged from automatic bleed valve, too. |
