Rotary machine for mixing, pumping or agitating a fluid and a method of mounting

A rotary machine for mixing, pumping or agitating a fluid comprising:

• an impeller configured to act on the fluid;
• a drive unit including a drive motor and configured to rotate the impeller around a rotation axis;
• a drive shaft connecting the impeller with the drive unit;
• a mounting flange configured to fasten the rotary machine to a wall of a vessel;
• a housing part disposed around the drive shaft and including a connecting part, the connecting part having a first side connected to the housing part and a second side, the second side being opposite the first side and being substantially planar, and the drive motor radially offset and detachably connected to the housing part;
• and
• a support structure configured to support the rotary machine, the support structure comprising at least one leg, each of the at least one leg extending in a vertical plane from a first end along a longitudinal axis to a second end, each of the at least one leg comprising an outer member and an inner member coaxially arranged in the outer member, the inner member slidingly movable relative to the outer member for adjusting the length of the respective leg, each of the at least one leg comprising a mounting plate at the first end of a respective leg, the mounting plate being substantially planar and configured to detachably mount to the second side of the connecting part of the housing part to fixedly mount the respective leg to the housing part of the rotary machine.
