WJF series dosing pumps are used in the field of oil open-collection and transmission. It uses the downward force of the swing arm of the pumping unit as the driving force to accurately add agents such as corrosion inhibitors and defoamers to the crude oil pipeline to prevent pipeline corrosion. To reduce hidden dangers of accidents and ensure safe production.

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.
