In transfer pump, its impeller has two wheel rims that are provided with concentrically of rotor blade, this rotor blade limits blade cavity, rotor blade has the pipeline of the part annular in pump case of corresponding configuration, such advantage is, before the pipeline of each part annular, connect an inlet pipeline, and the connecting tube of filter had two flow cross sections that are separated from each other respectively before entering the transition region of inlet pipeline.Thus, each in two inlet pipelines all extends in the zone of filter, thereby provides one section to be used for stable enough distances for fuel oil.
According to preferred design proposal, the flow cross section that is separated from each other forms especially simply by being arranged on the dividing plate in the connecting tube.
The radius that changes when the direction in the mobile trend at filter be at least the height of this regional flow cross section or width 20% the time, when importing fuel oil, avoided in fuel oil, promoting the eddy current of gasification of fuel oil along with the change of direction in the filter.
According to another preferred design proposal, avoided the eddy current of fuel oil in this wise owing to the variation of cross section, the change of the cross section in the trend that promptly flows is designed to continuous.
Good especially between filter and the transfer pump and being connected in this wise of sealing realize that promptly the connecting tube of filter is pressed into or sandwiches in the accommodating part of pump case, wherein, this accommodating part is arranged in the pump cover by the pump case that forms at the bottom of pump cover and the pump.
