Filtration systems

MaccPMPO1

PMPO presents its filtration systems, up to date with the most modern machine tools: 5-micron filtration systems; filtration systems with sludge compaction for emulsions or neat oil. These systems are aimed at companies caring about productivity and quality, in a clean and healthy working environment. In the current machine works market , a constant innovation is needed. Therefore, the use of filtration systems gives so many advantages that the filtration of lubricant and coolant fluids has become an additional activity aimed at the valorisation of the main production activity. The advantages of PMPO systems also positively influence the quality of the final products: thanks to the high quality of the filtered lubricant and coolant fluid, (medium filtration at 5 μm), the roughness incidence decreases and the grinding disc gives high performances for a longer time, so to limit the frequency of wheel dressing. Logistic advantages: With a plan dimensions of 2,5 m², it is possible to supply entire production lines or complete plants (rhuge space recovery). Economical advantages, that allow a fast return of the investment: the automatic regeneration of filtering parts and the longer life of the lubricant and coolant fluid (always clean and oxygenated) result in a reduction of administration and ordinary maintenance costs; the longer life of the lubricant/coolant fluids also allows  a reduction of the costs for waste disposal and the costs for the purchase of new lubricant/coolant fluids. These aspects highlight one of the main characteristics of the current filtering systems PMPO, that is the reduced environmental impact for companies that will install them.

 

HOW IT WORKS

The system uses a filtering part made of fibres, constantly keeping a dirt layer to regulate the filtration process. The software enhances the regeneration of the filtering part so to optimize the filtration/flow-rate combination. The degree of filtration can be modified simply by changing the parameters of the PLC or by substituting the filtering parts.

 

APPLICATIONS WITH MACHINE TOOLS

maniList of the main applications:

  • grinders
  • working stations
  • lathes
  • lapping machines
  • boring machines
  • rolling mills
  • drilling machines
  • tumblers

The treated lubricant and coolant fluids are:

  • emulsions
  • neat oils

Materials worked by the machine tools and filtering systems are:

  • iron
  • steel
  • brass
  • copper
  • alloy
  • nickel
  • chrome
  • calamine
  • hard metal

The solid structure is available also in stainless steel; it provides long life and strength. The filtering parts are created to last long and are protected against the action of any objects that might accidentally fall in the tank. Using a PLC allows the maximum adaptability to any production need.

 

YOUR PARTNER IN THE FILTRATION:

Three aspects have been carefully studied in the project in order to gain the client’s satisfaction on a long run:

  • reliability (any unforeseen event does not stop the machine from operating)
  • efficiency of the after-sale service:
    • maintenance (fast and cheap: the filtering parts are guaranteed for up to 5000 hours of operation)
    • technical support by telephone
    • remote support via modem

 

ECOLOGICAL WASTE, SUSTAINABLE ENVIRONMENTAL IMPACT

These two concepts, together with the improvement of the working environment’s safety and conditions, are essential to PMPO. This is why they were introduced in the planning stage of machinery, which is now sold both in Italy and abroad. The target was achieved, first of all, by creating a type of machinery with high quality performances (nominal filtration degree 5 micron); furthermore, the lubricant/coolant fluid is constantly oxygenated, and the tank that contains the dirty fluid is constantly washed. All this guarantees that no fungi are formed, preventing bacteria growth as well(controlled bacteria proliferation 104 ÷ 105 N bacteria / ml after 12 months); plus, bad odors that come from the tanks containing stagnant fluids are eliminated. Last but not least, it also allows to ease tank maintenance. No more skin infections, bacteria-induced pathologies or fungal infections for the workers. The environmental impact is strongly reduced with PMPO systems, also because no additives or other means are used during the filtering process (such as paper and fossil meal) so that the extracted sludge is suitable for a waste requalification. Several types of sludge extraction are available for various purposes. Particularly, sludge can be dried out at the 90% also for lubricant and coolant fluids with neat oil. In this case, the environmental impact and the reduced expensed for the oil purchase are remarkable.

 

PROFESSIONALITY IN AN AREA WITH MANY VARIABLES

The filtration field might seem easy; however, there are many variables to evaluate to determine the proper machine for the right type of process, lubricant and coolant fluid, processed material and customers’ needs. In this field, it is very difficult to give assurances regarding the proposed equipment. However, this is not the case for PMPO. Thanks to the experience with the machining process and the reliability of the working collaborations with clients and suppliers, PMPO not only can give assurances, but it can also guarantee them. In the advance-sale stage, PMPO technicians carry out inspections at the client’s premises and provide complete layouts that will be used to manufacture the equipment. During the purchase order, specifications that the equipment must guarantee are finally defined: filtration degree, filtered lubricant and coolant fluid capacity, quantity of daily extracted sludge. The client is never exposed to a risky deal because PMPO, after having analyzed the application, guarantees the proposed solution at the purchase moment. During the visits at the clients’ premises any additional parts for the industrial filtering equipment are also defined.

 

ACCESSORIES

The following accessories are available. They have been studied and tested for a long life, for the treatment of dirty fluids that contain strongly abrasive material:

  • booster tanks of the dirty coolant fluid from the machine tools to the filtering system
  • oil separators (for the extraction of extraneous oils from the emulsion)
  • coolant systems embedded in the filtering systems
  • heat exchangers
  • pneumatic valves
  • electric pumps
  • electric or pneumatic level controls
  • automatic refilling of the lubricant/coolant fluid
  • inspection window
