Apparatus and method for moving viscous fluid by pressure

An apparatus for removing a viscous fluid from a first unit (1) comprising a hose or pipe (7) through which the viscous fluid during operation of the apparatus is pumped from an outlet (11) of the first unit (1) to an inlet (10) of a second unit (2), the apparatus further comprising a pump (12) 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) comprises an inlet (8) for gas, and flow of the gas through the inlet (8) is controlled by a valve (9), and opening of the valve (9) is adjusted when the apparatus is set up for operation, and then the opening of the valve is constant until manual or automatic re-adjustment of the opening takes place, wherein

• the pump (12) is a pressure 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), by increasing pressure in the first unit (1) and thereby forcing the viscous fluid through the hose or pipe (7).
