Welded Steel Power Frame
The LTI power frame is unmatched for performance, reliability and sheer toughness. Designed for discharge pressures as high as 7,500 psi, it's an independent, precision fabricated structure of double-wall welded steel, with stiffeners and gussets for added strength and durability. As opposed to pumps mounted on an integral skid, the LTI mud pump comes mounted on a heavy-duty oilfield skid for easy mobility and superior alignment capability, significantly reducing component wear from increased internal stresses.

Balanced Forged Alloy Steel Crankshaft
Available only on pumps manufactured by LTI, the power-balancing crankshaft dramatically reduces noise and vibration and extends bearing and crankshaft life. Rather than using a multi-piece bolted component, the LTI crankshaft features one-piece, forged and fabricated construction, heat-treated for maximum durability. It's completely repairable (unlike a cast crankshaft) to help minimize operating expense, and its eccentric bearings are lubricated via drilled internal passageways — a longevity feature available only on LTI mud pumps.

Forged Alloy Steel Pinions and Gears
Double-helix or herringbone gear sets provide outstanding load transmission and quiet operation, while heat treatment maximizes strength and durability.

Triple-Redundant Power End Lubrication
LTI's triple-redundant, filtered lubrication system includes internal gravity/splash plus internal/external force-feeding of most power end bearings and upper/lower crosshead slides. For fail-safe protection even at very low operating speeds, the system includes a gear-driven mechanical pump off the main gear and a second pump driven by electric motor.

Fluid End Modules
LTI manufactures fluid modules in one- or two-piece configurations using quenched and tempered forged steel material. In most cases, we can furnish fluid end modules compatible with the mud pump brands you already use, eliminating the need to stock extra spares. All fluid end expendables are on-the-shelf parts readily available from domestic and international sources, further minimizing any need for additional inventory of spare parts.

Modified-Buttress Threaded Cylinder Heads and Valve Covers
For quick and easy access to valves and liners, LTI pioneered modified-buttress thread locks.

"Super Nuts" on Main Bearing Cap
Used in lieu of hex nuts, super nuts eliminate the need for special installation tools that are not commonly available on drilling rigs.

Steel Connecting Rods
LTI's rolled-plate, low carbon steel connecting rods maintain precise alignment between crankshaft and crosshead under maximum load. These rods feature double-row cylindrical roller bearings in the crosshead end and single-row cylindrical bearings in the crankshaft end, minimizing wear and friction under severe operating conditions.

Discharge Manifolds
Made of forged, heat-treated steel for maximum ruggedness, LTI discharge manifolds are designed to provide reliable connections and easy module maintenance. They're available in working pressures of 5,000 and 7,500 psi, and in various flange outlet configurations with clean-out strainers. On LTI WH-Series pump models, the single-piece trepanned manifold mounts directly to the backs of the fluid ends to eliminate connections between the discharge modules. On W‑Series pumps, the discharge manifold is mounted on the front of the module.
