Document Type and Number:
WIPO Patent Application WO/2015/170650
Kind Code:
A1
Abstract:
[Problem] The objective is to provide a pumping device which has good maintainability and with which a constant quantity of a fluid can be transferred without pulsation. [Solution] This pumping device (10) has a pump mechanism portion (20) that is provided with a uniaxial eccentric screw pump mechanism (25) formed by combining a stator (22) and a rotor (24). Furthermore, the pumping device (10) has a support structure portion (60) that can support the pump mechanism portion (20) in a state of being immersed in a fluid that is being stored in a storage tank (15), and a discharge path (100) that is connected directly or indirectly to the stator (22) and leads the fluid discharged from the stator (22) to the exterior of the storage tank (15). The pumping device (10) can assemble and disassemble the pump mechanism portion (20) by moving the rotor (24) in the axial direction in relation to the stator (22) which is being supported by the support structure portion (60).
