This　study　presents　a　novel　cylindrical　vane　pump　based　on　the　traditional　working　principle.　The　efficiency　of　the　cylindrical　vane　pump　was　verified　by　experimental　validation　and　numerical　analysis.　Numerical　analysis,　such　as　kinematics　analysis,　was　performed　in　Pro/Mechanism　and　unsteady　flow-field　analysis　was　performed　using　ANSYS　FLUENT.　The　stator　surface　equations　were　derived　using　the　geometric　theory　of　the　applied　spatial　triangulation　function.　A　three-dimensional　model　of　the　cylindrical　vane　pump　was　established　with　the　help　of　MATLAB　and　Pro/E.　The　kinematic　analysis　helped　in　developing　kinematic　equations　for　cylindrical　vane　pumps　and　proved　the　effectiveness　of　the　structural　design.　The　maximum　inaccuracy　error　of　the　computational　fluid　dynamics　(CFD)　model　was　5.7%　compared　with　the　experimental　results,　and　the　CFD　results　show　that　the　structure　of　the　pump　was　reasonable.　An　experimental　test　bench　was　developed,　and　the　results　were　in　excellent　agreement　with　the　numerical　results　of　CFD.　The　experimental　results　show　that　the　cylindrical　vane　pump　satisfied　the　three-element　design　of　a　positive-displacement　pump　and　the　trend　of　changes　in　efficiency　was　the　same　for　all　types　of　efficiency　under　different　operating　conditions.　Furthermore,　the　volumetric　efficiency　presented　a　nonlinear　positive　correlation　with　increased　rotational　velocity,　the　mechanical　efficiency　showed　a　nonlinear　negative　correlation,　and　the　total　efficiency　first　increased　and　then　decreased.　When　the　rotational　velocity　was　1.33　n　0　and　the　discharge　pressure　was　0.68　P　0　,　the　total　efficiency　reached　its　maximum　value.
