2 MANY POSSIBILITIES TO LUBRICATE YOUR MACHINE ACCURATELY AND RELIABLY Oil lubrication and 33v System for BALL SCREW SUPPORT BEARINGS, PROFILE RAIL GUIDES, SEALS Total loss and fluid grease lubrication involves creating a thin oil - film between moving parts which is renewed at regular intervals by an automated lubrication system. Recirculating Oil lubrication The oil is controlled both in quantity and temperature, it is collected by drains piping and returned to a supply tank. The oil is therefore re-circulated back to the point. Air/Oil lubrication The Vip4 Air System offers one of the most compact and feature rich air/oil systems available for spindles. Minimal Quantity lubrication and Near Dry Machining for TOOL Lubricant Aerosol is transported to the cutting surface by way of two methodes: External lubrication with pump, Internal or through-the-tool lubrication with MKD pump. 33V Systems This System consists of the latest direct positive displacement injector technology developed by Dropsa. This technology provides precise and fail-safe dosage of oil independent of viscosity, temperature or pressure. When combined with a competitive pump package, high performance system can be obtained at good prices. Our push-lock system allows further reduction in installation cost. 33V Systems Air-Oil Sensor Air-Oil Sensor This sensor controls the oil passage in the air, to the spindle bearing. Compressed Air MKD Dropsa has taken the minimal lubrication concept one step further with the VIP4Air that can achieve ultra-low volume oil discharge and at the same time provide electronic monitoring (using a custom designed differential flow sensor integrated into the unit). This allows true minimal lubrication by applying micro-amounts of lubricants at more frequent intervals whilst giving positive feedback that oil is correctly being injected and mixed into the air stream. The VIP4Air System contains all components necessary to achieve and monitor optimum minimal Air/Oil Lubrication. MKD The MKD-Dual minimal lubrication system represents the first step towards the world of near-dry machining by using the leading air-oil aerosol technology. Designed in particular for internal lubrication processes, this exclusive unit can generate a thin film of aerosol mixture which is brought directly to the tool cutting point by using the existing fluid distribution channels found on most machines. The auto-regulation is one of the key characteristics of MKD-Dual you will not find on other aerosol generators for near dry machining. It can be used on all the systems that need a calibrated lubrication and a functions control. It is possible to insert up to 8 elements connected among themselves that can be individually controlled via an integrated solenoid. For each single element it is possible to control individually oil and air delivery or use all the modules in tandem making the system easy to configure for each user application and control system. The system includes a scavenge device that rapidly recoils oil from the delivery line to prevent lubricant drip when powered down. Smart3 Compact and versatile pump, the perfect solution for oil and fluid grease lubrication. Thanks at 2 available versions, the lubrication cycle can be managed by an external PLC (MANUAL VERSION) or with an integrated controller board (AUTOMATIC VERSION). Gear Pump These new pump units have been designed as the result of over thirty years experience in the field of developing and manufacturing gear pumps. The application possibilities are numerous; the pumps are self-lubricating and are able to operate with oils or any other fluid with proved lubricating capacity. These pumps can therefore be utilised in the fields of lubrication, refrigeration, hydraulics and, more generally, for the circulation of fluids. Gear Pump Zone Valve This valve can be used in applications where it is necessary to isolate parts of machine. Smart 3 DragonX DragonX Compact and versatile pump that joins efficiency and performance in a simple all-inclusive pump package for injector and progressive systems both for oil and fluid grease NLG000. The external position of the pressure manifold block that houses all the functional components makes it easy to carry out any adjustments and connections.

3 LUBRICATION SOLUTIONS FOR A STANDARD MACHINING CENTERS Grease lubrication and Progressive Divider for BALL SCREW SUPPORT BEARINGS, PROFILE RAIL GUIDES, SEALS Grease lubrication has a wide field of application ranging from small machines such as woodworking machinery to large heavy industry such as steel plants or paper mills. The Progressive Divider distributes the flow of a pump into separate 'progressive outlets' by the use of a progressive spool arrangement. Positive lubrication feedback for all of the points can be achieved by monitoring one outlet with a cycle sensor. Air -Oil Lubrication The oil-injected into the air stream at regular intervals coats the surfaces to be lubricated and reduces friction and wear. These small all-enclosed devices are ideal for use on small systems and offer fully integrated control and monitoring in a single compact package. Typical applications: High Speed Bearings, Spindle Lubrication in machine tool, Micro-Spray Coating applications, Gear Lubrication, Chain. Minimal Quantity Lubrication & Near Dry Machining for TOOL A lot of benefit for your production: - Reduction of work cycle times, generally by 25% to 80%. - Increased of tool life thus increasing time among replacements. - Better surface finish and tolerance can be achieved. - Eliminate coolant plant more environmentally friendly. -Parts finish machining with a fine rust inhibiting oil coating - Not coolant contamination. - Water and oil consumption drastically reduced. NP & NPR Dropsa s nano-progressive (np) dividers are the ideal solution for oil and grease lubrication applications that require small and accurately dispensed quantity of lubricant in a compact solid and reliable footprint. The nano-np uses the progressive movement of pistons to allow precise quantities of lubricant to be accurately dispensed to multiple points. Thanks to a patented RigidLock, novel interlocking mechanism between the elements it has the rigidity of a mono-block divider but the flexibility of a modular segmented unit. Dropsa s nano-progressive Replaceable (npr) dividers uses an innovative rail & lock concept to allow the element to be replaced or re-organized without the need to completely dismantle the assembly. npr np Master SMX DIvider SMX DIVIDER The modular system consists of two main components: the base and the metering elements. Conventional bridging pieces are eliminated. Bridging elements have been introduced and these interconnect and discharge to the adjacent element. The distributor assembly principle enables factory floor distributor assembly to accommodate grouping of lubrication points. This revolutionary system makes the assembly easy and flexible; there is no need to determine in advance the size of the base, just add on distributors in unlimited number by means of very simple threaded inserts supplied for the assembly (Patented). LOCOPUMP S3 The Locopump S3 grease is an ideal single acting pneumatic grease pump generally used in single line progressive divider lubrication systems. It comes equipped as standard with a spring loaded 2 kg reservoir which means it can easily handle NLGI Grade 2 grease. The transparent reservoir allows the user to clearly see the quantity of grease remaining and a low level grease switch is present to provide remote alarm signals to the machine it is mounted on. Additionally, the reservoir lid can be modified to install a High level or a Dropsa continual level sensing device. Compressed Air Locopump
