Part number and flow rate »

In certain manufacture contests, emulsifying and cooling liquids filtration requires highly evolved systems or groups; automatic filters which can self-activate also for the self-cleaning of the system itself, by keeping constant the quality and quantity of filtered liquid and expelled waste.
PROFESSIONAL SYSTEM represents a filtration group designed and manufactured on purpose in a compact way, able to face and solve the filtration problem of lubricating-cooling liquids also in highly productive systems.

The filters frame is made of Stainless Steel AISI 304. The machine Body, the bearing frame and the chambers are made of painted steel.

The system core is made of polyester filtering discs by us patented » (see)
They represent, all together, a very vast total filtering surface with high flow rates of filtered liquid:

• 11.000 litres / hour in the individual filter model
• 22.000 litres / hour in the double filter model

The manufacture technology tested also in other industrial contests, makes this system an autonomous group. In the complete configuration all is carried out automatically: self-cleaning, recovery, drain and solid metal waste disposal.

Applications

It filtrates liquids coming from industrial processes, cut emulsifying, washing liquids and so on..
Ideal for:

• Mechanical industries
• Wood chip removing machines and grinding 
• Mechanical workshops
• Work centres

It ensures filtration speed and the utmost recovery of interesting liquids ( economic saving in the long term).

Filtration rate

The filtration rate ranges from 5 to 500 microns, according to the filtering discs used inside the filters.

Operation in filtration: see figure beside

The liquid to be filtered (1) is taken from a collection bath and conveyed inside the tangential flow spin filter (2) which is equipped with a number of patented high filtration degree filtering discs.
The combination of the liquid to be filtered tangential flow and the inlet pressure produces a forced passage of the liquid itself inside the filtering discs and it is ducted inside a collection bath (3) of the filtered liquid and re-generated (see filtering discs).

Self-cleaning - (see figure beside)

The filter self-cleaning cycles from residuals cumulated inside are automatically carried out with the same impure liquid destined to filtration » (see)
The set Control Unit sends the impulses to the hydro-valve (shut during normal filtration). This opens and the waste is expelled and collected inside a residuals automatic recovery bath (4), while the cleaning liquid goes back into the dirty liquid bath (1). The solid residuals are then automatically expelled into another bath (5).

During the self-cleaning cycle the system continues filtration. No manufacture stop occurs. Filtration is continuous and constant in time (filtration never stops).

Maintenance

If use and dimensions are proper maintenance is pretty much null.
The patented compulsory back-washing system avoids the waste accumulation on the filters which is then expelled by the cleaning cycle.
