The NOV C-250 is a mud and slurry pump rated by factory data at 2860 PSI max working pressure and 306 GPM max flow, with 250 HP rated input power, an 8 in stroke length and 150 SPM rated speed. Factory liner data lists a 5 in bore delivering 306 GPM at max 1400 PSI and a 4 in bore for 196 GPM at max 2190 PSI, with smaller bores reaching up to the 2860 PSI ceiling. Our replacement liners use a high-chromium bimetallic build — a hardened inner sleeve above HRC62 for wear and corrosion resistance bonded to a premium forged steel shell by centrifugal casting, with a precision-honed bore that reduces piston wear and extends service life. DOME supplies these OEM-compatible parts to contractors in Canada, the United States and international markets.
