Abstract
A tank for a pump is disclosed, which can accommodate a fluid for pumping, such as a chemical liquid. To a lower portion of a tank body which has a pump accommodation recess formed on one side, a weight member is removably secured. Prior to the securing, at the tank installation site the inner space of the weight member is filled with a weight material, such as water or sand, through an opening formed in the upper portion of the weight member. By so doing, when the residual quantity of the fluid for pumping in the tank body of the tank after the installation is reduced to be small, the tank is held in stable state by the weight of the weight member.
