Open the catalog to page 4Oil & Gas From onshore to offshore, dosing solutions in the oil and gas industry must cope with stringent technical specifications and harsh environmental conditions. In upstream, midstream and downstream applications, operators require process and metering pumps for chemical injection to achieve: • Equipment protection • Sour water stripping • Flow production • Gas dehydration • Produced water treatment • Deoiling • Hydrate control • Closed drain • Crude oil processing • Flushing It is essential that pumps in this sector are capable of high accuracy, repeatability and linearity, even under...
Open the catalog to page 5Power Generation Metering pumps are an essential aid to water treatment processes in thermal power plants, with their capacity for achieving highly-accurate dosage and flow rates making them ideal for injecting water-treatment chemicals into make-up water under pressure. Key water-treatment processes in power generation include: • Phosphate dosing to prevent scale formation in boiler tubes and maintain pH value to stop corrosion • Dosing of compounds such as ferric chloride and sulphuric acid for water purification • Metering caustic soda and detergent for CO2 scrubbing • Denitrification...
Open the catalog to page 6Oleochemicals The oleochemicals industry - the extraction of products such as fatty acids, fatty alcohols, methyl esters, fatty amines and glycerine from animal or vegetable fats - is a valuable and sustainable alternative to chemicals from hydrocarbon oils. Oleochemicals are used in a multitude of products, including toiletries, soaps, food additives, surfactants, detergents and biofuels. Critical processes in this sector include: • Saponification • Fractionation • Transesterification • Hydrogenation Pumps used in oleochemical processing must contend with a number of demanding...
Open the catalog to page 7Desalination In many parts of the world, seawater desalination is an essential process in the supply of potable and irrigation water. Both thermal (MSF/MED) and membrane (RO) desalination systems rely on precise and effective chemical dosing in order to prevent biofouling, scaling, foaming and corrosion. Chemical injection pumps must deliver first-class metering accuracy for the dosing of flocculants, coagulants, acids, chlorine and antiscalants that help deliver safe drinking water and maximize the world's most precious resource. Thanks to advances in pump technology, operators are now...
Open the catalog to page 8High temperatures and continuous duty are just some of the challenging conditions faced by pumping systems in the extraction and refining of metal from the ore. Modern steel mills produce a variety of metals, meaning pump flexibility is a key asset and the reason operators increasingly seek versatile systems to perform processes including: • Water treatment for the pre-cooling process • Treatment of sealing water • Descaling of carbon steels • Cleaning of ferrous alloys • Tailings and wastewater treatment • Acid injection for ore flotation Cement Production The dosing of additives,...
Open the catalog to page 9Nexa Series Hydraulic double-diaphragm and packed plunger pumps with full-motion mechanisms Capable of superior performance in even the most severe operating conditions, the Nexa Series packed-plunger and hydraulic double-diaphragm metering pumps represent one of heavy industry’s most versatile, robust and reliable fluid metering and dosing solutions.
Open the catalog to page 10Nexa’s exceptional build quality enables stable dosing even under extreme operating pressures and temperatures, from wellhead chemical injection in oil and gas applications to pyrophoric liquids handling in chemical compounds manufacturing. Designed to meet API 675 3rd edition standard, compliant to ATEX2014/34/EU, TR CU 004-010-020-012/2011 and alignable with Shell DEP (various), Norsok M-501 & M-630, NACE 0175 specifications, Nexa can be safely operated in hazardous processes, reassuring operators of the pump’s suitability regardless of the application. Technical Features Pressure: up to...
