PROBLEM TO BE SOLVED: To provide a pump test device greatly shortening the necessary operation time for a pump to reduce the cost for pump test. SOLUTION: A pump test device comprises: a bearing temperature sensor 20 measuring a temperature of a bearing of the pump 10; and an outside air temperature sensor 30 measuring an outside temperature of a place where a pump 20 is installed. The pump test device further comprises: a memory means 50 storing a model expression of the bearing temperature including at least an unknown coefficient, a variable indicating the bearing temperature, and a variable expressing the outside air temperature; and a calculation part 52 assigning the bearing temperature measured by the bearing temperature sensor 20 and the outside air temperature measured by the outside air temperature sensor 30 to the model expression to determine the unknown coefficient, and calculating the bearing temperature thereafter based on the model expression.
