Suction of contaminated lubricants, pumps for dense mixtures and very viscous oils.

Difficulty on extracting and aspirating contaminated lubricants.

peristaltic pumps for suction of contaminated lubricants

The purpose of the application is to simplify the aspiration and replacement of contaminated lubricating mixtures in the gearboxes and drive units present in the wind turbine generators. The maintenance operations foreseen on the wind generation devices are quite frequent. Particularly difficult is the extraction of a type of lubricant which has the consistency of a fluid grease which, once its tribological properties have been exhausted, is replaced also because it contains a significant quantity of contaminating metallic microparticulate generated by the normal wear of the mechanical components.

The dense and viscous consistency of the lubricant creates various complications for maintenance purposes. The biggest problem is the difficulty in aspirating the contaminated lubricants of the gearbox. Our customer experimented different solutions to solve problem without reaching the desired efficiency levels. The different type of pumps put into the test, did not meet expectations, or proved to be ineffective or even damaged very quickly.

Also involved in the affair we were asked to offer our solution. We proposed a pump that would certainly have been the ideal solution for the suction of contaminated lubricants. A HCP 15 peristaltic pump equipped with a very compact electronic speed variation system.

The peristaltic pump, a good solution.

The small unit is particularly light and manageable, easily lifted up to the wind generator’s nacelle. Once started, the large vacuum produced by the HCP 15 peristaltic pump allows the suction of contaminated lubricants and dense mixtures with simplicity. The possibility of varying the flow rate of the pump allows to maximize the performances according to the different viscosity of the sucked lubricating fluids.

The light and compact inverter that the pump is equipped with is managed with a practical keypad with very simplified functions to be used by any operator.

The pump naturally is selfpriming capable and does not damage if it works occasionally dry. The pump do not suffer any damage generated by the presence of solid metal particulate present in the lubricating mass. The machine fully met the expectations of the customer, who with a modest investment was able to equip himself with a definitive solution, easy to use and truly effective for the aspiration of contaminated lubricants.

Deep suction pumps.

Application purpose: deep suction of water inside oil and petroleum products tanks with peristaltic pump.

deep suction sef-priming peristaltic pumpThis company operates in the processing and trade of petroleum products, one of their main needs is the deep suction of water deposit inside accumulation tanks of heating oil an petroleum products. This is done as much for the main production installation, and as an additional service to customers tanks. Apart from the obvious fiscal and functional purposes  for which this practice is necessary, we come to the actual requirements that a pump must assure to perform this particular duty.

The main feature request is the deep suction capability, the machine should be able to operate easily with at least 8 meters height negative head, the pump has work with great effectiveness by generating minimum turbulence possible, to avoid stirring. The reversible in line capability is required, without the need to remove the pipes or other. The pump must be able to operate without any problems even in the presence of sedimented substances and any impurities. The commissioning and use should be extremely simplified, with easy maintenance and cleaning.

A last feature was requested by a customer, the pump carries out certainly a service rather light and occasional, but it is absolutely necessary that service should be granted with effectiveness and reliability with no any problem. The customer, made its considerations, chose a Hose Carrier HCP 25 peristaltic pump complete with mechanical speed variator and control panel.

The peristaltic pump entered into service has not disappointed the expectations developing a 9,5 meters vacuum allowing the deep suction without troubles of limpid or impure liquids, the variator allows to adjust speed to avoid turbulence, no damage in case of  dry running, full reversibility in line, put in service in few instants without problems. The peristaltic pump operates from the year 2012 no spares required till now.

Pumps for chemical cleaning.

Application purpose: chemical cleaning and descaling, industrial plants, recovery of wastewater and sludge with peristaltic pump.

peristaltic pump for chemical cleaningThis company operates in the field of chemical cleaning and washing of industrial systems, plants and components. These operations take place inside the company in the special tanks prepared for the purpose or directly on the customer plant, in case it is not possible to disassemble it. This last condition, also known as CIP (cleaning in place),for the obvious reasons is the most widespread.

The cleaning and washing operation is effected by the flushing special chemical cleaning agents acidic, basic and neutral. Are generally used, sulfuric acid, hydrochloric acid, sodium carbonate, soda etc. All the substances used for these operations, have characteristics of aggressiveness certainly relevant, it is taken for granted that the machines and pump equipment used for that task must be perfectly compatible in order to ensure the expected service life. But the important point of this application is another, during the washing operations, sometimes mud and abrasive media resulting in the waste.

The normal pumps used by our customer certainly are chemically compatible, but totally unsuitable for the treatment of muddy and abrasive sewage. In addition, during the washing phases, in certain situations, the liquid flow is discontinuous, exposing the conventional pumps to a dangerous operation in dry condition or intermittently, with continuous phases of priming, condition that sometimes resulted in damage to the sealing system of the pumps.

The peristaltic pump solution.

Sometimes the fluid is collected in flexible tanks placed and moved from time to time in different areas of the plant, these tanks having modest heights. The required pump must be capable of operating with minimum flooded condition level, the pump must be suitable of operating intermittently and with speed priming capabilities. The perfect solution was found by choosing a peristaltic pump HCP 25, with compact dimensions, good performance, absolute capacity and rapid priming, full chemical compatibility, and capable to operate with fluids with a very different viscosity, with solid abrasive suspension and obviously dry proof capabilities. Simple tasks for HCP 25 peristaltic pump .

heat pump, wells for geothermal heating and peristaltic pumps.

Peristaltic pump for construction of wells for geothermal energy with heat pump.

heat pump and peristaltic pumpA major european company, specialized in foundation works, in recent years, has introduced a division that deals with installation of geothermal plants with heat pump.These plants provide the realization of the wells drilled in the ground for the installation of geothermal piping and sensors. These wells are typically low-depth, up to a maximum of 150 meters and small diameter. Inside of the wells are inserted the vertical geothermal sensors consisting in polyethylene pipes with plant connections. Subsequently, the wells are isolated by filling with a specific material that is placed between the pipes and the bore of the well. The filling material, in addition to the thermal conductivity must also ensure a low solubility, to avoid interaction with the groundwater and must also guarantee a good elasticity to avoid collapsing of the soil, the filling material most commonly used is a grout, cement-based and bentonite, which serves perfectly to this function and is widely used in the engineering of specialized foundations. The mixture looks like a thick mud but rather fluid. The operation of isolation of the well is of fundamental importance for the purposes of the maximum thermal output, and must be made perfectly before connecting the geothermal wells and the heat pump plant. To effectuate the preparation and transfer of the bentonite mixture, two pumps, Hose Carrier HCP 6.5 have been purchased. The pumps are realized with compact dimensions and equipped with a mechanical variator to adjust the flow rate easily. The customer placead the pump on custom skid complete with electrical panel and protections so is possible control the pump, directly on board of a vehicle, or on construction yard. The two pumps operate by 2011 with an annual consumption of 4 tubular membranes. Which makes us assume that should work with particularly intense rhythms.

Pumps for the suction and transfer of the release agent and lubricant for moulds die casting.

 Release agent pumping, a different approach.release agent pump for die casting

A company belong to an important group operating in the production of die castings in aluminum, needed a rational system for the management and recovery of the release agent, and lubricants used in the steps of molding the cast components. Each machine has a collection tank that of a few centimeters in height size, however, may contain several hundreds of liters of contaminated feed materials to be recovered and treated. Each tank was equipped with a submersible pump of the conventional type. Of course, because the height of the collection tank is of a few centimeters, were used submersible pumps for clean water to obtain a suction level as low as possible, obviously, hydraulics of such pumps, is not suitable for the transfer of contaminated fluids and with solid substances in suspension. In addition, the pump worked most of the time with the engine in the air without cooling. This situation has caused the inevitable destruction of a large number of submersible pumps. The increasing costs and the continuous functional uncertainties have made necessary the total rethink of the process of recovery and treatment of the release agent.

Among the various solutions available, was chosen to produce a new plant which involved the use of a Pump Hose Carrier HCP 5.0 that sucks in a centralized manner by a suitable collector provided with pipes arranged in each collection tank, the large capacity of the pump suction hose carrier HCP 5.0 would have produced the vacuum inside the collector every time is necessary to empty the tub, it would have sufficed to open the appropriate valve arranged. The plant was built on the occasion of the summer stop and is regularly entered in function to the reopening of the productive activity. The solution adopted has produced immediately significant positive effects. Not only the Pump Hose Carrier HCP 5.0 was able to produce a great suction effect, but thus made possible to aspirate the solid suspensions present in the release agent that for their nature is not possible to deal with submersible pumps. Of course the Hose Carrier pump is not affected by a possible dry operation or discontinuous. We would also point out that between the aspiration point , and the point where is located the pump, there is a distance of over 150 meters and six meters of altitude. The cost of the management of the pump is a tubular membrane per year, really negligible.

On the occasion of a definitive rethinking of the implant, verified on the field the validity of the solution chosen, were introduced some practical automations to the system of the manifolds in suction. The Pump Hose Carrier HCP 5.0 has been replaced with the largest HCP 6.5 with variable speed equipped with integrated inverter with automation provided for the final implant for release agent.

The “old” HCP 5.0, is now placed to the treatment plant of the separating fluid in the implementation phase, and the recovery and the transfer of the muddy substances produced during the manufacturing process.
