Every graphite ring we machine starts as a grey block — and ends up keeping a pump running

Inside Lepu's workshop: carbon graphite components going from raw blank to finished part.

Grey blanks in a heap, discs stacked by the wall, then the lathe — turning the bore, cutting the grooves, drilling the bolt circles, splitting a solid ring into segments. What comes off the bench is a spread of graphite rings and sleeves in a wide range of diameters. Carbon graphite is self-lubricating, which is why it keeps showing up in pumps and rotating equipment wherever the liquid film runs thin.

Need a mechanical seal for centrifugal pump or mechanical seal for water pump duty — or a cartridge mechanical seal for multi-stage pumps, or mechanical pump shaft seals, or mechanical seal replacement parts for equipment already in service? Lepu builds them in Guangzhou and ships worldwide. Send us a drawing, a sample, or a part number.
