Elastomeric Polymer Used in Pump Bearing, Shaft Seals

INDRON® elastic-plastic polymer alloy composite(referred as elastic-plastic for short) has the advantages of low friction and light wear, effectively reducing the wear of friction pairs. INDRON® bearings can be widely used with water power and hydraulic machinery such as hydro-electric installations, clean energy generation, ships and offshore installations, which uses water as lubricant instead of mineral oils and thus avoid leakage and release of mineral oils.The surface hardness of INDRON® hRBR is relatively low. Giving way to the burial of abrasive grains and transferring them from the friction pair to the water tank to discharge them can guarantee the most wear-resistant grade in INDRON® elastoplastic alloy. The performance remains excellent in the medium of high sediment content.What bearing materials are more suitable as the materials used for water pump guide bearings, Babbitt alloy, rubber, ceramics or new polymer materials? It is advisable to take account of the lubrication requirements, use environment and maintenance cycle of the equipment.COMMON GUIDE BEARING MATERIALSBearing typeINDRON bearingAR bearingCeramic bearingRubber bearingBabbitt alloy bearingCharacteristicsThe performance is close thordon, which can use more equipment assembly methods. In addition to traditional installations by freezing and pressurizing. It can also be installed by coating reactive thermal polymerization Dx and cold sticking.Good wear resistance and impact resistance. The bearing hardness is high; the shaft sleeve is easy to wear; the temperature difference changes greatly; there will be the risk of shelling; the price is high.Wear-resistant, heat-resistant, corrosion-resistant, lubricated by pump circulating water, capable of dry grinding for a short time, high requirement on accuracy in processing and assembly, fragile and the most expensive.It has a long history and mature manufacturing process, featured by wear resistance, anti-seismic, impact resistance, convenient assembly/disassembly and low price (only 20% of ceramic bearings price)Wear resistance and impact resistance require a set of more complicated sealing and lubricating devices and mechanisms.Lubricating requirementsClean water can be used for lubrication or 150s dry start according to the material grades.Dry start more than 180S without clean water lubrication.It can be lubricated by pumping medium without special clean water lubrication.Clean industrial waterGrease lubrication requires a grease supply lubrication system.Working temperature≤70ºC≥273ºCThe bearing itself can withstand the temperature of 1,400ºC≤50ºC≤65ºCShort time up to 80ºCApplication siteFor pumping stations short of clean water or pumping stations requiring short-term dry friction, hRBR grade is suitable for water quality with moderate sediment content.Pumping stations without clean water or pumping stations requiring dry friction of more than 180S.Pumping stations without clean water or pumping stations requiring short-term dry friction.Extensive application in any pumping stations with clean water sources.The liquid of the pump itself cannot be used for bearing lubrication in the pumping station.Bearing typeINDRON bearingAR bearingCeramic bearingRubber bearingBabbitt alloy bearing/* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
