Big parts get the same treatment as small ones — machined to drawing, measured before they ship.

Not everything that leaves Lepu fits on a workbench. These two flange rings are heavy steel discs, black-finished and fully drilled — one with radial slots cut clean through the face, the other with a raised machined hub and two full circles of bolt holes. The caliper resting against the pallet gives you some idea of the scale.

Parts like these come to us as drawings, or as the worn originals pulled off the machine. We machine them to match — bolt circles, slots, hub diameters — then measure the critical dimensions before anything gets packed. One piece or a batch, the process does not change.

Heavy machined parts sit alongside our core range: mechanical seals for rotating equipment, mechanical pump shaft seals, mechanical seal replacement parts, and OEM pump mechanical seals built to order. If you need a part that nobody seems to stock — a flange ring, a sleeve, a seal housing — send us the drawing. We will quote it, machine it, and ship it from Guangzhou.
