Product BenefitsPressurized components are subject to the most rigid quality control within the scope of a highly efficient quality assurance system. A long service life is ensured by a minimum corrosion allowance of 3 mm.2 x API allowable nozzle loadsImpellers with a high accuracy of shape and excellent surface finish, resulting in high efficiencies special suction impeller ensure low NPSH valuesExchangeable impeller wear rings on suction side of the impellers, exchangeable wear rings in the stage casings, exchangeable stage bearing bushes at the rear-side impeller hubs serve to protect the diffusers and act as bearing guide. Clearances according to API 610.Low-vibration operation due to dynamic balancing both of the individual impellers and of the complete rotor.Special suction impeller designed as the first stage at the lowermost point of the barrel, and thus full utiliztion of the suction head resulting from the barrel length.Adaption to the available NPSH value by lowering the first stage and adding column pipes.Stage casings with metallic seating are bolted to the suction and discharge casing.Oil-lubricated anti-friction bearings with constant level oiler.Interstage bushes and additional guide bearings lubricated by the liquid handled.FEA was used to analyze the stand to assure that pumps operate well away from any natural frequencies per API610Smooth operation with low vibration levels due to static & dynamic balancing of impeller and other rotating parts.ISO-13709 (API 610) Table 6 seal chambers for improved seal life.Fits for mechanical seals as per ISO 24109 / API 682 in cartridge design for easy installation and removal
Product OptionsMaterials variety acc. to API 610Various types of cartridge mechanical seals availableDesign available for non-Hydrocarbon ApplicationsImpeller trimmed to match the specified duty pointWide range of hydraulic designs to suit all applicationsGrease or oil lubricated bearing bracketA variety of instrumentation options are available for monitoring all key operating parameters (temperature, pressure, vibrations, etc.)Circular or rectangular sole plate available
