WJF 系列加藥泵用于石油開采集輸領域，它借助抽油機擺臂的下行力作為驅動力，可精確地向原油輸送管線中投加緩蝕劑、消泡劑等藥劑，防止管道腐蝕，減少事故隱患，保證安全生產(chǎn)。

WJF series dosing pump is a non-power source adjustable metering pump with patented technology of our company. Under the action of external force, the plunger is reciprocated up and down, and the medium is conveyed through the opening and closing of the check valve. It can transport -30 ℃ ～ 150 ℃, viscosity 0.3 ～ 800mm / s without corrosive and non-corrosive medium with solid particles. According to different technological process requirements and medium characteristics, special functions such as high viscosity, strong corrosion resistance, high temperature resistance dosing pump can be selected.
