Operating principle
TR drum pumps are designed for immersion use only (see
minimum and maximum levels), incorporate suitable protection
against the formation of a vortex and consequent suction of air
bubbles and should be positioned vertically. The impeller is
situated internally at the end of the dip tube (suction) directly
connected to the (electric or pneumatic) motor and rotates
until reaching the maximum speed, thus creating a suction and
pumping chamber for the liquid that reaches the pump discharge
conduit for transfer with the maximum head.

In particular, IT IS FORBIDDEN to use the TR drum pump for:
- pumping petrol and/or flammable liquids;
- operating in explosive atmospheres;
- operating with different (min. and max.) immersion levels to
those indicated on the pump;
- pumping potable liquids;
- use with the opposite direction of rotation to that specified
- suction use in the presence of vortex, turbulence or air bubbles;
- dry operation;
- use with liquids to be pumped that are chemically incompatible
with construction materials;
- use with products in suspension whose specific weight is
greater than that of the liquid (e.g. water with sand);
- with product temperatures and characteristics of the pump;
- with water that is particularly hard and/ or full of deposits.

The hazards associated with use of the pump in the cor-
rect conditions as described in the use and maintenance
manual, have been studied; the assessment of hazards
associated with the interaction with other plant compo-
nents and/or the type of installation is assigned to the
installation operator.
