A three-stage variable color paste pump, comprising: a differential pump, which includes: a rodless cavity, a rod containing cavity, and a piston rod; configuring a control valve, which comprises a valve body and a valve core, wherein the valve body is provided with a rod containing cavity opening which is in communication with the rod containing cavity; configuring a rodless cavity opening as in communication with the rodless cavity, configuring a color paste tank opening as in communication with a color paste tank, and configuring an injection outlet; configuring a channel on the valve core, moving the valve core to different positions may form three communication structures. The pump uses one differential pump to achieve three-stage injection output, thus ensuring the accuracy of the injection output of the color paste pump. The pump has a simple structure, takes up a small surface area, and is easy to use.
