To provide a pump system and a pump housing which enable manufacturing of a highly-rigid housing without using welding work to reduce the manufacturing cost.SOLUTION: Each support pillar 21 comprises: a shank 21c in which two plates 21a, 21b having longitudinal directions in the vertical direction and plate width directions intersecting with each other are joined; and extension portions 21d that extend from one plate 21a of the shank 21c in a direction of one side of a rectangle of a housing frame 1 and from the other plate 21b in a direction of the other side intersecting with the one side of the rectangle, respectively. Each end frame 22 comprises a rectangular base 22a, and protruding portions 22b that extend from each side of the rectangle of the base 22a in an upper direction or in a downward direction. The shank 21c has an end located between one of the protruding portions 22b and the other protruding portion 22b adjacent thereto, and an upper end edge 21e of the extension portion 21d is in contact with an end edge 22c of the protruding portion 22b.SELECTED DRAWING: Figure 3 【課題】溶接作業を用いなくても剛性の高い筐体を製造可能として、製造コストを低減できるポンプシステム及びポンプ用筐体を提供する。【解決手段】各支柱２１は、上下方向を長手方向とし板幅方向が互いに交差する２枚の板２１ａ，２１ｂが接合されている軸部２１ｃと、軸部２１ｃの一方の板２１ａから筐体フレーム１の矩形状の一辺の方向に、他方の板２１ｂから前記矩形状の一辺と交差する他の一辺の方向に、それぞれ延出している延出部２１ｄとを備え、各端部フレーム２２は、矩形状の１枚の基部２２ａと、基部２２ａの矩形状の各辺から上方向又は下方向に延出している張出部２２ｂとを備え、一の張出部２２ｂと、これと隣接する他の張出部２２ｂとの間に軸部２１ｃの一端部が位置していて、延出部２１ｄの下端縁２１ｅと張出部２２ｂの端縁２２ｃとが接している。【選択図】図３
