This firm has launched a new pump-type series (photo) for use in the chemical and petrochemical industries. The pumps meet the requirements of API 685 Standards, and the series comprises 27 sizes designed for a minimum of 20 years of operation in a petroleum refinery under heavy-duty conditions and at pressures of at least 40 bar. The casings with their centerline pump feet and the flameproof motor housings are provided with a corrosion allowance of 3 mm. Throttle rings on the front and rear shrouds of the impeller and balancing holes, together with a hydraulic-pressure balancing chamber, ensure that the axial forces are absorbed. The new series generates a maximum flowrate of 350 m3/h and a maximum discharge head of 200 m. — Nikkiso-KSB GmbH, Bruchköbel, Germany
