摘要： 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.

摘要： The present invention relates to a device for pumping a moist pulp and may be used in the wood-pulp and paper industry for conveying a highly concentrated pulp. The proposed pump comprises a body (1) having a hopper (2) for receiving a pulp; a replaceable pipe connection (3) in which a worm feeder (5) is coaxially located; a check valve (6) mounted as viewed from a pump outlet from said pipe connection (3); and a mixing chamber (4) for mixing the pulp with a carrying agent; said chamber is coupled with said pipe connection (3) and fitted with a means for supplying the carrying agent. Between the worm feeder (5) end and the check valve (6) an adjustable gap is provided. On the surface of the pipe connection, on the level of the last flight of the worm feeder there are provided longitudinal through splines (8) for evacuating air which have a length of not more than a lead of the last flight of said worm feeder, a width of about 0.2 - 1.0 mm and a total open area of from 0.5 ΔS to ΔS, where ΔS means the difference between an inner sectional area of the pipe connection and a sectional area of the worm feeder rod. The proposed pump enables pumping over a moist pulp of a high concentration (16-90 %) with maximum efficiency at different sectors of production lines of paper making industry with the result that a need for using a system for the pulp dilution with water is ruled out, a total quantity of waste waters and energy expenditures to treat thereof are reduced.
