CORRECT USE AND NOT ALLOWED USES

The filter pumps are designed to filter electrolytic solutions used in the following processes: 

The machine is not designed to pump or filter liquids other than the ones already listed. For specific applications, it is suggested to contact OMG technical dept.

Regarding electrolytic solutions, the filter pump is absolutely unsuitable for:

1. chrome-plating treatment baths;
2. highly-concentrated fluorine baths;
3. baths containing organic solvents such as chloroform.

Anyway, the liquid’s temperature mustn’t be higher than 70° C.
 

EMPLOYED MATERIALS

Electrolytic solutions usually consist of a water base combined with acids (for ex. Hydrochloric or sulphuric acids), chlorides and the metals to be deposited for example nickel, silver, copper, zinc, cadmium, tin.

The filter-pump is made of anticorrosive materials to withstand acids and all the dangerous substances usually contained in galvanic baths. This is meant to prolong the working life of the components and to better prevent the risks of accidental contacts.
In particular:

• the pump body and the rotor are made of polypropylene (also called Moplen), with silicon carbide mechanical seals;
• in TE series the filter tank has an internal coating made of a protective elastomer (ebonite);
• in all models, the mechanical components are made of stainless steel AISI 316 L or AISI 304;
• the supply-included chemical resistant discharge and suction pipes have been selected by the 
• manufacturer OMG; the suction ones are also reinforced by a steel spiral to avoid flattering due to lack of pressure.

In the CESE and TE series the choice of all the mentioned materials, and particularly the way of construction of the filtering block (inserts/papers sequence), are a guarantee of high filtering surface and, therefore, a high filtration degree (filtration < 1 micron).

In particular, according to the different pump models, the filtering surface is between 0,2 mq and 20 mq
