Note:4. When the roots pump is combined with a water ring pump, water in the water ring pump may flow into the roots pump when the unit stops, resulted in emulsification of oil in gear box of the roots pump after a certain period. Our company equips a liquid stopper at inlet of the water ring pump and an air pocket between the water ring pump and roots pump so as to prevent the backflow, thus the unit is more reliable.
