    Abstract: A pump for pumping fluid comprises a pump housing which comprises a fluid inlet, a fluid outlet, a pumping chamber fluidly connected to the fluid inlet and the fluid outlet. Within the pumping chamber is provided a rotatable impeller for drawing fluid from the inlet and displacing the fluid out of the fluid outlet. The pump also comprises a drive source adapted to generate a drive force for rotating the impeller; a drivetrain assembly coupling the drive source to the impeller so as to transmit the drive force to the impeller, wherein the drivetrain assembly comprises a rotatable element arranged between the drive source and the impeller so as to transmit the drive force. The pump also includes an an ancillary device comprising a rotatable input element and the rotatable element of the drivetrain assembly is arranged such that it can be coupled to the rotatable input element of the ancillary device by an endless flexible mechanical element and thereby drive the rotatable input element when coupled by an endless flexible mechanical element. Additionally, the drive source, the drivetrain assembly and the impeller define a plurality of transmission elements and a pair of the transmission elements are spaced apart. The drivetrain assembly also comprises a moveable connecting element for coupling the spaced apart transmission elements, the moveable connecting element being moveable between: a first position in which the spaced apart transmission elements are coupled so as to enable the drive force to be transmitted from the drive source to the impeller; and a second position in which a gap is formed for allowing an endless flexible mechanical element to be threaded between the spaced apart transmission elements to allow the endless flexible mechanical element to couple the rotatable element and the rotatable input element of the ancillary device.

    Abstract: A chain tensioning arrangement for a column pipe which is configured to house a submersible pump. The chain tensioning arrangement includes a radially extending cross beam, a spring arrangement connected to the cross beam, at least one spring member, and an arm that is movably connected to the cross beam. The arm includes an engagement member configured to optionally engage a chain connected to the pump. The arm is displaceable in the axial direction between a lower position and an upper position. The spring member is arranged to displace the arm in the direction from the lower position towards the upper position. Also described is a pump station including a column pipe, a submersible pump arranged in the column pipe and an axially extending chain connected to the pump and configured to move the pump in the column pipe.
