プ。[Claims for Utility Model Registration] (1) A hole that communicates with the cylinder body (referred to as the "main cylinder body") of the reciprocating pump is bored in the tip of the existing reciprocating pump, and this hole A base end opening of a sub-cylinder body formed of a corrosion-resistant material is communicated with the sub-cylinder body, and an inlet port and a discharge port are formed in which a suction valve and a discharge valve respectively formed of a corrosion-resistant material are disposed. and a sub-piston made of a corrosion-resistant material that is slid in the sub-cylinder body can be inserted into and removed from the main cylinder body through a sealing means disposed in the base end opening and passing through the hole. An existing piston that is inserted and slides into this main cylinder body (referred to as the "main piston")
1. A chemical pump, characterized in that an elastic member is contracted to the tip of the sub-cylinder body and can press the sub-piston in the direction of the main piston. (2) The chemical pump according to claim 1, which is a registered utility model, characterized in that a space means is interposed at the tip of the sub-cylinder body, so that the volume inside the sub-cylinder body can be arbitrarily changed. .
