Pump barrel inner wall adopts the advanced gas carbonitriding process, has good wear resistance, corrosion resistance. Extension of upper and lower are respectively connected at the two ends of the pump barrel coupling, the size of the inner hole diameter is slightly larger than the pump barrel, so as to ensure the plunger in the stroke, lower dead point beyond the pump barrel length.
