Zusammenfassung:	To prevent a total load of operating pumps from going beyond an allowance while reducing an excessive operation time of pumps compared to a case where a new pump is started, when the total load of operating pumps reaches a value obtained by subtracting a constant value from a total rated load.SOLUTION: A pump control device 20 has: an acquisition unit 20A that acquires the number of pumps in operation, which is the number of operating pumps 10 in operation among a plurality of pumps 10 that discharge gas from a tank; and a control unit 20B that performs control to newly start stopped pumps 10 when a total load of operating pumps 10 reaches a value obtained by subtracting a margin value determined for each number of pumps in operation from a total rated load of operating pumps 10.SELECTED DRAWING: Figure 2 【課題】運転中のポンプの合計負荷が、定格負荷の合計から一定値を減算した値に達した場合に、ポンプを新たに起動する場合に比較して、ポンプの過剰な運転時間を削減しつつ、運転中のポンプの合計負荷が許容値を超えないようにする。【解決手段】ポンプ制御装置２０は、タンクからガスを払い出す複数のポンプ１０のうち、運転中のポンプ１０の台数である運転台数を取得する取得部２０Ａと、運転中のポンプ１０の合計負荷が、運転台数毎に定められた余裕値を運転中のポンプ１０の定格負荷の合計から減算した値に達した場合に、停止中のポンプ１０を新たに起動させるように制御する制御部２０Ｂと、を有する。【選択図】図２
