Power End: the cornerstone of forging strength and precision engineering
Frame construction: a solid skeleton for stability
The T-1300 power end frame is a rigid structure welded with thick steel plates, and after completion, the overall stress relief heat treatment is performed to obtain superior rigidity and strength.
Driveline: Precise and efficient power transmission
Crankshaft and gears: the crankshaft is forged in one piece from high strength alloy steel (e. g. 42CrMo) and subjected to a rigorous multi-stage heat treatment process to provide high strength, toughness and fatigue resistance.
Bearing configuration:
Main bearings: Double Row self-aligning roller bearings are used at both ends of the crankshaft, which can bear huge radial load and adapt to minor misalignments that may occur during installation.
Connecting rod bearings: Single Row short cylindrical roller bearings are used at the big end (eccentric wheel) , double row long cylindrical roller bearings are used at the small end (cross pin) , this combination is designed to withstand high radial impact loads in reciprocating motion.
Pinion shaft bearings: single row long cylindrical roller bearings, ensure the accuracy of gear meshing and transmission efficiency.
Lubrication system: the lifeblood of durability
T-1300 power end of the use of forced lubrication and splash lubrication of the combination of dual lubrication system.
Hydraulic end: to overcome wear and corrosion with advanced materials
Hydraulic cylinder module: pressure core
Hydraulic cylinder modules are precision machined from monolithic forgings of high quality alloy steels such as 35CRMO, 4135 or AISI 8620. We use the classic Valve-over-Valve structure design, which effectively reduces the clearance volume of the cylinder, thus significantly improving the volumetric efficiency of the pump. For corrosive drilling fluid, we also provide electroless nickel plating surface treatment options to provide a dense protective layer on the inner surface of the hydraulic cylinder, greatly improving its corrosion resistance and erosion resistance.

Pistons, valves, and piston rods: delicately designed wear parts
Piston: the piston core is forged from high strength 42CrMo alloy steel and quenched and tempered to ensure that it does not deform under high pressure. The piston skin is made of high-performance polyurethane (PU)
Or nitrile rubber (NBR) * * material, through a special curing process and core firmly bonding. Polyurethane materials work well in oil-based muds, while nitrile rubber is ideal for water-based muds.
Valve Assembly: the body and seat are forged in one piece of high quality alloy steel (e. g. 40CrNiMo) followed by carburizing heat treatment to achieve an HRC ≥60 work surface hardness, sufficient to withstand the tremendous impact and fluid flushing each time the valve is opened or closed. We offer a variety of valve designs, including full open and four-ribbed, to optimize the throughput of drilling fluids with varying densities and solids.
Piston rod and intermediate tie rod: these key connectors are made of high quality alloy steel (e. g. 45 # steel) with induction hardened and chrome plated rod surfaces. The induction hardening forms a hard surface and a tough core, while the chromium plating after precision grinding provides an extremely smooth and corrosion-resistant surface, which effectively reduces the wear of the packing seal and prolongs the service life of the seal.
