The utility model discloses a pull-type concrete pumpability tester. The tester consists of the following five basic parts, namely a pipeline, a front-rear baffle piston device in rigid connection with a connecting rod, a constant speed sliding traction mechanism, a force measuring and recording instrument and a support bracket, wherein the front-rear baffle piston device in rigid connection with the connecting rod is positioned in the pipeline; the gap between the front and rear baffles is used for loading tested concrete; the constant speed sliding traction mechanism is used for pulling the front-rear baffle piston device to slide in the pipeline; the force measuring and recording instrument is used for measuring the tension and/or pressure; and the support bracket is used for mounting the pipeline, the constant speed sliding traction mechanism and/or the force measuring and recording instrument. The tester disclosed by the utility model can be used for simultaneously measuring the pumpability and pumping simplicity and is accurate in measurement result, simple in structure and reliable in performance.
