3.2. GENERAL SAFETY INSTRUCTIONS

Read the instruction manual carefully before installing and starting the agitator. Contact INOXPA in

case of doubt.

3.2.1. During the installation

The Technical Specifications of chapter 9 should always be observed.

The installation and use of the agitator should always be in accordance with applicable regulations

in regard to health and safety.

Before starting up the agitator, check that it is properly anchored and its shaft is perfectly aligned.

Incorrect alignment and/or excessive stress during coupling can cause serious mechanical

problems in the agitator.

Take all possible precautions when lifting the agitator. Always use properly attached slings when

moving the agitator with a crane or other lifting device.

Keep the motor and the switchboard under control, particularly in areas where there is a risk of fire

or explosion.

When cleaning, do not spray directly on the engine.

Do not disassemble the agitator until the switchboard has been disconnected. Remove the fuses

and disconnect the power cable supplying the motor.

All electric work should be carried out by specialised personnel.

3.2.2. During operation

The Technical Specifications of chapter 9 should always be observed. Under no circumstances can

the specified limit values be exceeded.

Before starting up the agitator, remove all the tools used during the assembly.

Do not operate the agitator when the rotating parts are not equipped with their guards or are not

properly assembled.

The agitator has rotating parts. Do not place hands or fingers in the agitator while it is operating.

This may cause serious injuries.

Do not touch the parts of the agitator that are in contact with the fluid when in operation. When the

agitator operates with hot fluids (temperatures above 50ºC), there is a risk of skin burning. In such

cases, collective-protection means (in this order or priority: separation, protective screen, heat-

insulating material) or, in the absence of this, individual protection gear (gloves) must be used.

ATTENTION

Safety

INOXPA S.A.U. 20.003.30.02EN · (A) 2021/12 7

The agitator and its installation can generate sound levels above 85 dB(A) under unfavourable

operating conditions. In such cases, the operators must use devices for protection against noise.

3.2.3. During maintenance

The Technical Specifications of chapter 9 shall always be observed.

The agitator cannot operate without fluid. Standard agitators are not designed to work during the

filling or emptying of tanks.

The maximum operating conditions of the agitator should not be exceeded. Nor should the

operating parameters for which the agitator was initially designed be modified without written

authorisations from INOXPA.

Do not leave loose parts on the floor.

Do not disassemble the agitator until the switchboard has been disconnected. Remove the fuses

and disconnect the power cable supplying the motor.

All the electric work should be carried out by specialised personnel.

4. General Information

4.1. DESCRIPTION

The BMI series range is vertical agitators with a stainless steel base and a lip seal as a sealing system.

Although these agitators are very compact, they have a bearing bracket which is totally independent of the

motor. The half shaft is guided by one or two bearings which withstand the axial and radial forces transmitted by

the agitation element. The agitator shaft is directly attached to half shaft with two allen studs.

4.2. OPERATING PRINCIPLE

The agitators are usually installed off-centre to prevent product rotation but can also be installed centred in

conjunction with deflector baffles in the tank.

The rotating propeller pushes the product towards the bottom of the tank, where it is diverted generating an

upward flow along the tank walls so that the product reaches the surface of liquid. This effect is enhanced if the

tank has a rounded base.

4.3. APPLICATION

The BMI vertical agitators can be used in mixing, dissolution, dispersion and maintenance processes requiring

strong agitation at high speeds, as well as in the food processing, cosmetics and chemical industries selecting

the appropriate finish in each case.

Applicable to tanks with capacities of up to 10.000 litres usually with low viscosity products.

Each agitator has performance limits. The agitator was selected for a given set of mixing conditions

when the order was placed. INOXPA shall not be held responsible for any damage that might be

suffered or malfunctioning of the equipment of the information provided by the buyer is incomplete

or incorrect. (e.g. nature of the fluids or installation details).
