To provide a solution transfer device capable of preventing a solid material from being accumulated onto a sliding part of a pump mechanism which is shaft-sealed such that solution does not get into a gap between a cylinder and a piston, and has such the pump mechanism as to suck and eject the solution in accordance with motion of the piston sliding in the cylinder.SOLUTION: A solution transfer device includes: a pump mechanism main body which is shaft-sealed such that solution does not get into a gap between a cylinder and a piston, and sucks and ejects the solution in accordance with motion of the piston sliding in the cylinder; and purge gas charging means which is provided on an outer part of the pump mechanism main body and charges purge gas into the gap between the cylinder and the piston. Therein, solvent charging means is provided on an outer part of the pump mechanism main body, a solvent charging tube of the solvent charging means is fluidically connected with a purge gas charging tube of the purge gas charging means, and solvent is charged into the gap between the cylinder and the piston at the same time with the purge gas or intermittently.SELECTED DRAWING: Figure 3 【課題】シリンダとピストンの隙間に溶液が入り込まないように軸封され、前記シリンダ内を摺動する前記ピストンの運動によって溶液を吸込み、吐出するポンプ機構の摺動部への固形物の蓄積を防止できる溶液移送装置を提供すること。【解決手段】シリンダとピストンの隙間に溶液が入り込まないように軸封され、シリンダ内を摺動するピストンの運動によって、溶液を吸込み、吐出するポンプ機構本体と、ポンプ機構本体の外部に設けられ、シリンダとピストンの隙間にパージガスを注入するパージガス注入手段を備えている溶液移送装置であって、ポンプ機構本体の外部に溶媒注入手段を設け、溶媒注入手段の溶媒注入管を、パージガス注入手段のパージガス注入管と流体的に接続し、溶媒をパージガスと同時または間欠的にシリンダとピストンの隙間に注入するように構成されている。【選択図】図３
