Leistritz screw pumps of the L4 series are twin screw, double volute, self-priming, positive displacement pumps for low, medium and high pressure duty, suitable for transport of abrasive/non abrasive, corrosive/ non corrosive, lubricating/non lubricating, high or low viscous fluids.
Leistritz Pump in Germany contacted Isomag to design a highly customized bearing isolator for their L4NG screw pump. The purpose was to keep with bearing lubrication, which was pressurized, inside the housing. For this Leistritz required a positive seal with a track record on long sealing life. Isomag beaing isolators were the perfect fit. Isomag bearing isolators are the default bearing isolators for the L4NG screw pumps and have been since 2013.
