CYZ series self-priming centrifugal oil pump is suitable for pumping petrol(gasoline),kerosene,diesel oil ect,and the temperature of medium is -20��-+80��.it’s eximious pump under the conditions of ship,land oil depot and tank truck and so on.It also can pump the seawater,freshwater etc.If pumping chemical liquid,it should be assembled corrosive-proof mechanical seal.This type pump has the characteristic of simple structure,strong self-priming ability,easy operation,simple and convenient repair,high efficiency,wide applications.

    The pump’s bearing adopts single row angular contact ball bearing with lubricating by Albany grease or #10 machine oil .
     There’s a coolingroom at the bottom of the bearing body in some type pumps .when bearing temperature rising exceeds 70��,could transfuse the coolant into coolingroom by pipe joint and circle cooling.
    The pump inner’s seal structure that prevent pumped liquid leak from high pressure room to low pressure room is front and back seal ring is assembled on the bearing body.When the seal rings fray to badly to operate normally,should replace them.
     The pump’s shaft seal adopts mechanical seal.
    The pump’s shaft seal adopts mechanical seal .
    The pump’s connection with driving motor is clawed couple with rubber.
