Abstract

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.

Description

technical field [0001] The invention relates to a pumping device, in particular to a flow control system for the pumping device. Background technique [0002] Pumping apparatus or pumping equipment, such as electric pressure pumps, pressure tank units, or fuel powered pressure pumps, including flow control systems, wherein said pumping apparatus or pumping equipment is commonly used in various types of water management applications including horticulture, Agricultural, industrial or domestic water supply. A typical flow control system includes a check or one-way valve with a closure member that moves between an open position and a closed position to allow fluid (eg, water) to flow in one direction only. The check valve may include restoring means, such as a spring, to apply a restoring force to the closing member to maintain the closing member in the closed position. Thus, in the absence of hydrostatic fluid pressure in the pumping device, the check valve prevents any back...
