1 INDEX ZGE CENTRIFUGAL PUMPS ISO 2 FOR CHEMICAL PROCESSING

2 ARGAL chemical pumps QUALITY AND EXPERIENCE From the artisan's workshop to the modern industrial plant, the strategy of Argal has always been the same: to invest in research and quality in order to obtain safe and reliable quality products. In many years' activity (Argal was set up in 1) manufacturing techniques and staff training have always kept abreast of the latest developments in pump technology. Today's company uses the lastest production techniques backed up by a technical department constantly developing through research and development. Using CAD, FEM optimisation and a fully equipped test and development facility the ARGAL product is being constantly improved. ARGAL's main goal is the same as its always been: delivering safe product that fully conforms to CE standards and the international standards that will ensure that the product wins it rightful place at the top of the world market. Since 1 ARGAL has obtained the certification of the Quality Management System according to the standard ISO 02. In 1, ARGAL changed from being a mere distributor of pumps to being a manufacturer of electric pumps. It developed its own technology, and combined the precision standards of craftmanship with a sound business organisation. Ten years later, in 1, Argal launched a new range of magnetic drive pumps. They are totally different from other pumps of their kind because of the new, acid and chemical resistant materials from which they are constructed. Today ARGAL has something else to offer: experience. Experience gained in the practical use of these pumps enables us to propose specifications that will work safely and identify those areas that may cause problems. A pump may seem to be correct for a duty in terms of flow, head, suction lift and motor power. However chemical resistance, viscosity, temperature, specific fluid characteristics, etc. are all factors that have to be evaluated when selecting a pump. Argal is the ideal patner. Togheter with the customer ARGAL and its sole Distributors will select the pump which is best suited to the task and will give the best long term performance. ARGAL can assist the customer with chemical/phisical data, calculations of friction losses, differential heads, NPSH, suction heads, priming times, etc. Our technical sales team are constantly expanding the knowledge and experience which is available to their clients.

4 MAIN FEATURES AND MATERIALS MAIN FEATURES ZGE pumps are a complete range of centrifugal chemical process pumps, built in compliance with ISO2 (Din 22 - BS2 - NFE 121). Standardisation of performance points and above all, the main constructional dimensions of the pumps, bases, couplings and shaft seals offers great advantages in total interchangeability of pumps and their component parts. CONSTRUCTION Centrifugal single impellers, with horizontal end suction and central top discharge. For maximum integrity pump bodies are machined from solid, with piping loads absorbed by the metal flanges of the volute casing. As "process" pumps they are designed to accept commercially available standardised mechanical seals. External, single or internal double with interseal flush can be installed (see choosing the right mechanical seal). The pump shaft is independently mounted in rolling element bearings designed to accept all dynamic loading from all operating conditions. The pumps are oil lubricated and are provided with a constant level oiler to ensure optimum performance. Pumps and drivers are mounted on a common base with drive via flexible spacer couplings (Din ) use of a spacer enables service of the pump without disconnecting pipework or removing motors (Fig. 1). Fig. 1 MATERIALS The materials that come into direct contact with the chemicals are extremely resistant to them.the FC, WR, WF, ER and QR versions of the pump and the many different types of seal are different combinations of the materials that can be used for the pump parts coming into direct contact with the pumped fluid. A selection of the correct combination of materials ( by consulting the compatility tables supplied by our customer service) involves rapidly examining the chemical composition of the liquid, its concentration and its temperature: doing this ensures that the most suitable pump will be chosen for a given application and that it will be operate within the required safety margins. MOTOR Standard specification for motor is : IP enclosure, class F insulation, suitable - phase, suitable for 0V +/-%, Hz (V +/- % Hz). Other specifications are available on request to meet specific customer requirements. PAINTWORK External metal surfaces are protected by an epoxy coating over an appropriate primer undercoat. Standard colour: Ral 2 orange. QUALITY The used materials are certified in the origin and in the composition. Upon request is available a final test according ISO 2 Class C. Spare parts undergo the same stringent inspection procedures to ensure complete inter-changeabilty (Fig. 2). APPLICATIONS THE RIGHT PUMP FOR THE RIGHT PROCESS. ARGAL pumps are suitable for acid, hydroxide and salt solutions in varying concentrations and at various temperatures; mixture of strong acids; electrolytic baths; aromatic hydrocarbons; chlorides and alchool. APPLICATION EXAMPLES Chemical and pharmaceutical processes. Petrochemical,chemical and agrichemical engineering. Textile Industries. Transfer, loading and distribution of chemical products. Spraying systems for metal polishing. Electro-plating treatments. Circulating pumps for heat exchangers in the electroplating and anodising industries. Reaction vessel circulation. Scrubbing tower for toxic gas removal. Fish farm water circulation. Thermal and sea water. Water purification. Fig. Fig. 2 WARNING ZGE pumps comply with EC standards on machine safety and are supplied complete with all the relevant documentation. The installation, operation and maintenance manual must be carefully read and scrupulously followed by the user (Fig. ). INDEX

9 CHARACTERISTICS OF MATERIALS AND PARTICULARS OF CONSTRUCTION VERSION FC WR WF ER QR PUMP CASING IMPELLER PLATE SLEEVEN METAL FLANGES SUPPORT BASE GASCHET PVDF PVDF PVDF PP PP PP PP PVDF PP PE PE PE PVC PVC PVC PVDF PP PP PE PVC CAST IRON CAST IRON STEEL FKM FC: The base resin is PVDF (polyvinilidene fluoride): This is a fluorinated plastomer that is highly resistant to abrasion and has a high degree of mechanical resistance. If used in centrifugal pumps, it can withstand peaks of temperature of 1 C and can operate continuously at C. It is extremely resistant to strong concentrated acids and has good resistance to organic solvents (except for Ketones, esters and acetone), extremely resistant to hot solutions of inorganic salts. WR: The base resin is PP (polypropylene): very good mechanical resistance, good resistance to heat deformation. If used in centrifugal pumps, it withstands peak temperature up to C; it operates continuously at C. It is extremely resistant to high concentrations of weak acids and high alkaline concentrations. Good resistance to cold concentrations of strong acids, excellent resistance to solutions of inorganic salts. WF: The base resin is PP (polypropylene): the parts that are subjected to particularly heavy duty are of PVDF in order to increase the pump resistance to wear and abrasion. It can operate continuously at temperatures of up to C. ER: The base resin is Pe (polyethylene 0 with a high molecular weight): it has as high chemical resistance as PP and is also resistant to many organic solvents. It is more suitable for use at low temperatures (down to - C) with an upper limit of + C for continuous use. QR: The base resin is PVC (polyvinyl chloride): it has excellent resistance to alkaline solutions and acids (in particular, chromic acid, sulphur-nitrate mixtures, sulphuric acid, sodium hypochlorite, turpentine and ozone). The pump can be used at temperatures of up to C. Elastomers used: E: EPDM ethylene-propylene rubber; high chemical resistance, not suitable for oils. V: FKM fluorine rubber; high chemical resistance, including many solvents. F: FEP fluorinated, ethylene-propylene copolymer; chemical resistance comparable to PTFE. INDEX
