We don't just manufacture pump sleeves. We build confidence into every repair — tight tolerances, hard chrome finishing and quality inspection on every unit that leaves our floor.
DuraChrome Engineering is a South African precision engineering company specialising in the manufacture and refurbishment of hard chrome pump sleeves for slurry and industrial pump applications.
We combine precision machining, quality materials and hard chrome expertise to deliver sleeves that perform under the toughest conditions — from mining slurry lines to power station cooling systems.
Every sleeve is precision machined and hard chrome finished in-house — off-the-shelf profiles or fully custom to your application.
Every DPN part number below with its outside diameter — the fast way to confirm the profile you need before you order.
