Hydrochloric acid

The purpose of the application: hydrochloric acid and Aluminum anodizing.

hydrochloric acid metering pumpThis company deal with surface treatments, and there is a lot to do with an annual production of about 7000 tons of Aluminum. The quality of the finishes has distinguished this company in the market, making it among the most important companies in Italy in this sector. Evidently to reach this important goal, it is necessary to pay particular attention to all production processes, and especially those in the preliminary analysis, and control, before each processing step.

The hydrochloric acid is widely used to perform the repeated chemical controls necessary to achieve a process of high quality finish that the company shall ensure. The sampling is done by drawing directly  from the baths the liquid to test, and subject it to various chemical controls. For dosing hydrochloric acid is used, a peristaltic pump HC 10 low pressure pump, with a fixed rotation speed, and particularly slow, in order to obtain a tubular membrane long lasting time.

Ease to use, high reliability in the priming, and the absolute compatibility with the hydrochloric acid, allow this little HC 10 peristaltic pump to make its important contribution in order to achieve the high quality standards desired by the company in the production processes.

The HC 10 is a small proportions peristaltic pump, but very sturdy and accurate, easy to use, does not suffer damage in case of dry running and is capable of developing a vacuum of 8 meters. Provides a instant and continuous self-priming effect. The tube membrane is compatible with a very broad spectrum of aggressive chemicals, its replacement is quick and simple and requires no special skills. Given the obvious talents shown by the first peristaltic pump, the customer introduced a second unit as a complement to the first.

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 .

Sulphuric acid pumping .

The purpose of the application: pumping sulphuric acid and waste products.

best solutions for sulphuric acid pumpingThis company deals with the recovery of metal, plastic materials and other chemical substances for the subsequent regeneration.In a production site, there is a particular type of plant that has the aim of recovering the industrial and automotive batteries.
From the recovery cycle, will get the lead, plastics and chemicals, sulphuric acid, sodium sulfate. In one of the initial steps of the recycling process the sulphuric acid accumulated by the emptying of the batteries must be pumped. The acid is collected in tanks and is contaminated by solid substances of various types, crystal formations, particles of plastic, metallic powders, acid slurries. The result is a fluid with significant characteristics of chemical and mechanical aggression properties. The fluid must be pumped with surface pumps in order to limit any security issues, the experiences in the past with centrifugal pumps have been very disappointing, with great difficulty on priming, rapid eterioration of the sealing systems, very frequent impeller clogging, continuous machine stoppages. The company experimented the use of pneumatic diaphragm pumps, but also in this case, there were significant problems on priming and aspiration (uncertain due to wear of the valve system, in case of rupture of the membranes, it often happened that the contaminated fluid passing through the membrane deteriorated, to the air distribution device destroying it irreparably. In both cases, the centrifugal pumps and the pneumatic ones, required the complete removal of the pumps from plant for maintenance. Given that the past experiences were not certainly positive, it was not easy to convince the company to experiment a different solution with another pump not very conventional. At the end we were able to introduce into the production cycle a  HCP 50 peristaltic pump in 2010. From that moment the company no longer had problems arising from the pumping of contaminated sulfuric acid. The peristaltic pump has an operating cost of three peristaltic hoses every year, without machine stops and substantial significant costs. In the course of 2016 another peristaltic pump HCP 50 has joined the existing one for further increase potential production .
