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 .

Pompa Hose Carrier HCP 5.0 con inverter su carrello

A well-known company engaged in the manufacture and sale of chemical substances and products destined to the car industry and transport, needed new pump for transfer chemicals with characteristics that are very variable. The raw materials and the products   made in the company are generally acidic or alkaline, dense or viscous, or very fluid, but with a tendency to determine phenomena such as foams. The operation which the pump has in charge start from emptying  the tanks for the transfer to production, to dosing into the container of the medium and the large proportion.

It is ideal that a single pump will be able to fulfil all the needs, adapting to the individual characteristics of the fluid, without complicated operations of adaptation. Among the various needs, there is also to move easily the machine in the manufacture areas according to the needs of the chemicals production cycle.

The company chose a Hose Carrier of the HCP 5.0-speed electronically variable, with a dedicated trolley. The pump can ensure to get a range from a few hundred litres up to 12000 litres times, work with thick fluids without difficulty, or pumping fluids, which generate foams without start this unwanted phenomenon. The full chemical compatibility of the pump avoid to prepare the machine for different tasks.

Granules, abrasive suspensions that may be present in the products, or processing waste contaminated can be pumped without any damage to the pump.

The presence of the inverter programmable allows simple dosing or interfacing with the sensors or the logic of the system that will be defined for the purpose. With a single pump, and no changes you will be able to pump many chemical based products or finished products such as, acids, bases, detergents, surfactants, degreasers, additives, solvents, emollients, and lubricants. Of course, the different viscosities are not a problem, as well as the possibility of priming capability that is guaranteed to dry without damage in the case of normal or intermittently operation, . Not bad for a single pump.
