摘要： An apparatus and a method are shown for removing or moving a viscous fluid such as grease from a first unit such as a bearing e.g. a ball bearing to a second unit via a hose or pipe. The apparatus includes a hose or pipe (7) through which the viscous fluid is pumped during operation from an outlet (11) of the first unit (1) to an inlet (10) of the second unit (2), wherein the apparatus further includes a pump connected to the hose or pipe (7) in such a way that the viscous fluid during operation is moved through the hose or pipe (7), and the hose or pipe (7) includes an inlet (8) for gas such as air, and the flow of gas through the inlet (8) is controlled by a valve (9).

摘要： A device for pumping a viscous fluid includes two positive displacement rotary pumps, a first pump (1) and a second pump (2), wherein each pump has an inlet (3, 4) for fluid at a suction side and an outlet (5, 6) for fluid on a discharge side, wherein the inlet (3) of the first pump (1) is connected to a reservoir of the viscous fluid by a connection (14) pipe or hose, wherein the apparatus further includes an intermediate part or connection (7) having an inlet (8), a first outlet (9) and a flow path (10) for fluid, wherein the outlet (5) of the first pump is connected to the inlet (8) of the intermediate part and the outlet (9) of the intermediate part is connected to the inlet (4) of the second pump, such that during the pumping the viscous fluid is forced from the reservoir through the first pump (1), through the intermediate part (7) and through the second pump (2) to the outlet (6) of the second pump.

摘要： By mounting a line blind valve (2) between a grease container (i) and a grease lubrication pump (3) replacement and mounting of the grease container can take place without leak of grease during the mounting as the outlet section must turn downwards during the mounting. By providing the installation with a line blind valve this can block grease leakage during the mounting and thereafter be opened. The valve (2) includes a flat central part (1o) with an opening (ii) which part can be displaced in relation to an upper positioned inlet section (4) and a lower positioned outlet section (8) and by displacement of the slide open and close for passage. In order to keep these parts (4, 8, 10) together a magnet (6, 7) is embedded in each of the two parts (4, 8) by which a sealed connection is secured with no air infiltration.
