Application purpose: deep suction of water inside oil and petroleum products tanks with peristaltic pump.
This 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.
Purpose of application, floating sludge and supernatant suction. A company specialized in the manufacturing of stainless steel makes use during the working processes of cooling lubricant that is collected in an underground tank. The cooling lubricant is constantly subjected to cleaning cycles and regeneration in order to eliminate the contaminants collected during use in the manufacturing processes. The perfect cleaning of the cooling lubricant is necessary in order to obtain levels of surface finishing of metal products according to the standards demanded by the manufacturer. In many cases, the metal surfaces are finished with mirror polishing. One of the various problems linked to the treatment of lubrofrigerante is the elimination of the supernatant and floating sludge or any agglomerated formations that form and stationed on the free surface in the tanks, the semisolid consistency of these formations puts in crisis the treatment plant of the cooling lubricant clogs pumps and valve systems. It is advisable to remove the formations supernatants possibly in the moment of maximum consistency and directly from the surface of the liquid in order to be able to eliminate the most contaminated. For this purpose have been arranged a Pump Hose Carrier HCP 2.5 equipped with a special filter Skimmer equipped with an overflow of collection able to float on the surface of the fluid. During the cleaning step, the spillway is located a few millimeters below the free surface and collects in its interior the supernatants and the floating sludges substances that precipitate due to gravity, the action of the pump removes these substances evacuandole externally in a bag filter. The Pump Hose Carrier is a machine perfectly suited to this purpose just for its remarkable suction capacity and the possibility of operating with solid substances of considerable size. No one of different kind of pumps previous used have enabled that company to achieve the efficiency of the Pump Hose Carrier. Since four years that the HCP pump 2.5 performs this service, and it has not requested any maintenance intervention , the tubular membrane is still that of first installation. We do not think it is necessary to add other things.
