Zusammenfassung: | To provide a small-sized pump device with a high lift while improving suction performance.SOLUTION: A pump device 100 comprises a plurality of pump units 1A, 1B, 1C connected continuously in series. Each pump unit 1 comprises: an impeller 14 in which the magnet 5 is embedded; a motor stator 6 arranged at a position facing the magnet 5; a pump casing 2 that houses the impeller 14; and a motor casing 3 that houses the motor stator 6. The first stage pump unit 1A located at the earliest stage among the plurality of pump units 1A, 1B, 1C has suction performance that allows handling liquid to be transferred at a desired flow rate to the second stage pump unit 2B following the first stage pump unit 1A.SELECTED DRAWING: Figure 2
【課題】吸込性能を改善しつつ、高揚程で小型のポンプ装置を提供する。【解決手段】ポンプ装置100は、直列に連続して接続される複数のポンプユニット1A,1B,1Cを備える。各ポンプユニット1は、磁石5が埋設される羽根車14と、磁石5に対向する位置に配置されるモータ固定子6と、羽根車14を収容するポンプケーシング2と、モータ固定子6を収容するモータケーシング3と、を備える。複数のポンプユニット1A,1B,1Cのうちの最も前段に位置する初段ポンプユニット1Aは、該初段ポンプユニット1Aに続く2段目ポンプユニット2Bまで取扱液を所望の流量で移送可能な吸込性能を有する。【選択図】図2 |
