Abstract: 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. According to the method, the apparatus is shown pumping a viscous fluid from an outlet (11) of a first unit (1) to an inlet (10) of a second unit (2) through a hose or pipe (7), a vacuum pump (3) is connected to the hose or pipe (7) and the viscous fluid is moved through the hose or pipe (7) by suction; wherein the hose or pipe (7) comprises an inlet (8) for gas such as air, and the flow of gas through the inlet (8) is controlled by a valve (9).

Abstract: A supply system has a pump unit and a support unit adapted to fit to the inner volume of a container holding a viscous fluid such as grease. The supply system pumps viscous fluid from a container (1) having an inner opening or volume, the supply system including a pump unit (2) having a pump (21) for pumping the fluid out of the container (1), and the supply system further includes a support unit (3) with a contact surface (7) facing the fluid inside the volume of the container (1) during operation wherein the support unit (3) is secured to the pump unit (2) such that the support unit and the pump unit (3, 2) move together, and the support unit (3) is movably mounted relative to the container (1) such that the support unit and the pump unit (3, 2) move relative to the container during operation.

Abstract: Inlets (3, 4) are provided for fluid at suction sides of first and second positive displacement rotary pumps (1, 2) and likewise outlets (5, 6) are provided for fluid on discharge sides, wherein viscous fluid pumped from a reservoir enters the inlet (3) of the first pump (1) and is discharged from the outlet (5), wherein an intermediate part or connection (7) is provided with 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 through the first pump (1), through the intermediate part (7) and through the second pump (2) to the outlet (6) of the second pump.
