Reducing the diameter of the tube is not the same as the import and export, a big, one small, and because you want to connect an external interface is different, so be adjustable, called reducers. Reducing the height of the tube due to the different and have different types of models, welcome new and old customers to consult! Two center-section adjustable tube port is not in a horizontal line, the pipe surface is horizontal line one side, over the edge is inclined eccentric reducer installation, horizontal edges upward, downward diagonal direction (for the purpose prevent suction pipe gas accumulation in this form cavitation); outlet adjustable tube called concentric reducer, two ports section adjustable tube center is in a horizontal line (like a cone dig remove steeple empty). Whether it is a big mouth end of the intake or outlet eccentric reducer concentric reducer, small mouth end is connected to the pump with the pump, eccentric reducer with the pump suction pipe connected concentric reducer big mouth end is connected with the pump outlet.
