Dropsa Lubrication Systems

Dropsa Lubrication Systems, an internationally renowned Italian company, synonymous with industrial lubrication systems, has chosen Mecgi as its expert partner and dealer. Since 1946, Dropsa Lubrication Systems has proposed and produced innovative and sophisticated solutions and components that improve the performance and life of all types of bearings, wheels, chains, guides, screws and gears, in small machines, transfer lines, printing machines, paper mills, steel mills and all industrial sectors.

From design to production, all processes undergo rigorous quality checks in accordance with ISO 9001:1994 standards. The use of leading-edge technology in the design and control of new products has led to extensive international recognition for DROPSA solutions and innovative projects.

Dropsa Lubrication Systems is a leader in the development of new products. The Research & Development department (R&D) designs, develops and produces continuous cycle prototypes. The concept of “modularity” based on which products are designed and developed allows flexible adaptation to requests for supply.

Dropsa Lubrication Systems

 

A worldwide company set apart by the high performance and quality of its products. The main feature distinguishing Dropsa products is the concept of modularity applied in its range of lubrication systems. The main advantages of this choice are:

  • Manoeuvrability
  • Possibility for expansion
  • Longer durability
  • Simplicity of maintenance and operations
  • Reduction in the cost and number of spare parts
  • Elimination of connecting tubes with subsequent reduction in possible lubricant leaks
  • Flexibility/interchangeability
All specifications of the various system types can be found in the Dropsa Lubrication Systems catalogue. Our company has a large warehouse of Dropsa components, guaranteeing clients first-rate service and timely deliveries. We can also provide technical information, recommendations and suggestions. Dropsa Lubrication Systems offers the reliability of worldwide technical assistance by a company with 50 years’ experience with ISO 9001 certification since 1995.

Oil circulation

The concept of circulation implies a continuous flow of oil right up to the lubrication point. The oil is collected in dedicated containers, whence it is directed into a tank, which then places it back into circulation, re-delivering it to the lubrication point. The pumping station is equipped with dedicated oil cooling and heating devices in order to keep the lubricant at its ideal temperature.
In oil circulation systems, a constant quantity of oil fills the housing of each bearing, while the rapid exchange of lubricant cools the surface, thus increasing the speed of production.

Total loss oiling lubrication

Total loss oiling lubrication creates and maintains a thin layer of lubricant, which envelops the moving parts. The latter are thus lubricated and cooled by an automatic system at regular intervals.   

 



Grease lubrication

Dropsa offers a complete range of equipment for grease lubrication and complete system monitoring. All types of grease applications can be designed and developed with a guarantee of reliability and efficiency thanks to the broad range of ready-to-deliver pumps, as well as the possibility for customisation to satisfy the most varying needs.

 

Dry machining or minimum quantity lubrication

The aim of dry machining is to replace traditional cooling or neat cutting oil systems with a flow of compressed air, thus generating a very thin layer of “mist”, which is conveyed through the spindle and cooling channels of the tool directly to the cutting point. This guarantees linear lubrication and high machining performance.

 

Two minimum quantity lubrication systems

The minimum quantity lubrication system can be used in two ways:

  • external lubrication (the air-oil mix reaches the surface through a nozzle)
  • internal lubrication or "tool-conveyed" (the air-oil mix - particles less than one micron - passes through the spindle and cooling channels of the tool and is delivered directly to the cutting zone). 

Advantages of minimum quantity lubrication

  • Reduces machining time by 25% to 80%.
  • Improved finish and piece tolerance.
  • The machined piece is covered by a layer of oil to prevent rust.
  • Significantly reduced water and oil consumption.
  • No need for complex regulations, thus saving time with the MKD-DUAL micro-mist self-adaptive system.
  • Eliminates costs incurred by high pressure with pumping and filtration system.
  • Extended durability of tool and increased productivity.

Progressive systems

A progressive and centralised lubrication system uses dosing units that distribute predefined quantities of lubricant to a certain number of elements. This occurs thanks to the action of a series of pilot pistons in interdependent succession. A progressive system is equipped with a pump, progressive divider valves and a control unit. The pump pushes a certain quantity of lubricant, which the progressive divider valves then split and send to the elements needing lubrication. Dosing occurs through the pistons, which only discharge the lubricant once the previous piston has already discharged.

Characteristics of progressive system

Serie 26 is the name of the modular system with progressive dosing unit, which offers a number of advantages including its design, making the most of its flexibility and allowing low maintenance costs.
The Serie 26 progressive system is mainly used for grease lubrication, but also for circulating oil lubrication. 
Serie 26 is designed to be used in separate zones where conditions are irregular, thus optimising lubrication of the machine or large system.
Applicable variables include the volume and frequency of grease required in each point, the number of points, management conditions and pump pressure.
The operation of a progressive system can be carefully monitored and controlled using special electric devices such as the “VIP Controller”. These devices can be quickly programmed through the special transmission of infra-red waves. SMX Progressive Dosing Units are also available in a 316 stainless steel version.  

 

Advantages

  • Can be used at high pressure
  • Easy expansion or modification of System
  • Modularity that also allows the rapid switching of elements, whether for modifications or replacements, without interrupting the distribution of the lubricant.


Typical applications:
  • Machine tools even on medium-sized systems
  • Transfer lines
  • Small-medium grease lubrication machines
  • Cement platforms, mining platforms, onshore and offshore platforms
  • Paper mills

Dual-Line System

The Dual-Line system has two main lines that are alternately operated by way of a valve.
A lubrication cycle is completed when both main lines are alternately pressurised and depressurised.
It is a parallel-type system and each dual-line valve works independently of the others in the system.

 

Characteristics of Dual-Line system

Dropsa allows a broad range of different configurations and allows the expansion of the entire system. Elements can be replaced during maintenance operations without needing to dismount the tubes. Typical applications include heavy-duty industrial machinery, for example in large steel mills. Distinctive features include simplicity and reliability even in particularly harsh environmental conditions. If a lubrication point is blocked or cannot be sufficiently lubricated, the rest of the system will not be affected and will continue to operate as normal. Dual-Line systems are often more than 60 metres long.

Advantages

  • Use of system even at high pressure (500 Bar / 7000 psi)
  • Possibility for easy modification and expansion of system
  • The modular Dual-Line system allows faultyelements to be replaced quickly without interruptions to the work of the tube.
  • Even when there is a blockage on an element, the rest of the system is not affected and continues to operate as normal, guaranteeing lubrication.


Typical applications:

  • Paper mills
  • Iron and steel machine shops
  • Cement plants
  • Platforms
  • Large cranes and loading equipment
