To provide a pumping distance specification system and a pumping distance specification method for concrete, capable of accurately specifying a pumping distance forcibly feeding concrete by the pump without blocking a pipe.SOLUTION: A pumping distance specification system 100 for concrete for filling the concrete in a pipe 40 of a test device 10, alternatively operating pumping means 11 to reciprocate the concrete over a pumping test time until the pipe is closed, and specifying a pumping distance based on a permissible integrated pressure receiving amount and a planned pumping amount at a unique construction site, includes an arithmetic operation device 50. The arithmetic operation device 50 has: a permissible cumulative pressure receiving amount calculation unit 510 for calculating a permissible cumulative pressure amount consisting of the product of a pumping reaction force that the pumping means 11 receives from the concrete and the pumping test time; a data storage unit 530 that stores various planned pumping amounts; and a pumping distance calculation unit 520 that calculates the pumping distance based on the permissible cumulative receiving pressure amount and the various planned pumping amounts.SELECTED DRAWING: Figure 1
