ンプ。[Scope of Claim for Utility Model Registration] A liquid feeding pump for a flow injection analyzer, in which an elastic liquid feeding tube made of silicone or the like is pressed against a plurality of rollers attached to a rotating head using a tube holder. In a liquid pump that sequentially moves the liquid in a liquid feeding tube using a roller that moves as the roller rotates, the mounting position of the roller is determined for each of the multiple (n) liquid feeding tubes arranged in parallel. The rotary heads are arranged so that the feeding pressure fluctuation period λ of the liquid feeding of each of the liquid feeding tubes is shifted by λ/n, and the plurality of liquid feeding tubes whose feeding pressure fluctuation period λ is shifted by λ/n are arranged. A liquid feeding pump characterized by having a structure in which liquids are combined and sent through a pressure buffer liquid reservoir.
