Provided is a pumping device (100) or a pump apparatus (200) including a flow control system (122, 220). The flow control system (122, 220) includes a non-return valve (124, 230) and an actuation mechanism (128, 242). The non-return valve (124, 230) have a closing member (126, 232) movable between an open position and a closed position to allow a unidirectional fluid flow and the actuation mechanism (128, 242) have an actuation element (130, 244) movable between an operative position and an inoperative position with respect to the closing member (126, 232). In the operative position, the actuation element (130, 244) applies a counteracting force (CF) to move the closing member (126, 232) to the open position and the actuation element (130, 244) is biased towards the operative position. 种泵抽装置(100)或种泵设备(200)，包括流量控制系统(122，220)。所述流量控制系统(122，220)包括止回阀(124，230)以及驱动机构(128，242)。所述止回阀(124，230)具有闭合部件(126，232)，所述闭合部件(126，232)在开启位置与闭合位置之间移动，以允许单向流体流动。所述驱动机构(128，242)具有驱动元件(130，244)，所述驱动元件(130，244)相对于闭合部件(126，232)在操作位置与非操作
