1.Detailed Product Introduction
All parts are direct TSC OEM equivalents, meaning they fit perfectly with the existing fluid end assembly of the LANSHI 3NB-1600—no field machining, drilling, or modification is needed, saving maintenance teams 1.5–2.5 hours of installation time per repair. Each component is crafted from field-proven, high-performance materials to eliminate common fluid end failure points: studs are made from heat-treated alloy steel for superior tensile strength ; gaskets are constructed from nitrile rubber with a reinforced steel core to resist high pressure and drilling mud contamination; valve guide bushingsfeature a hardened surface treatment to reduce wear and extend service life; liner bushings are precision-machined from high-carbon steel to ensure a tight, leak-free fit with pump liners. Every part undergoes rigorous quality testing—including pressure testing , torque testing for studs and nuts, dimensional inspection using CNC measuring tools, and material composition analysis—to meet API 7K and TSC OEM standards, ensuring consistent performance and reliability in the harshest drilling environments.
2. Core Functional Specifications
The fluid end is the backbone of the LANSHI 3NB-1600 mud pump, and each component in this parts list plays a critical role in ensuring smooth, efficient operation. The complete fluid end module (TS-107.11.110.00) integrates all key components into a single, ready-to-install unit, providing a one-stop replacement solution for full fluid end overhauls and eliminating the need to source individual parts. Studded fluid end modules (TS-107.11.110.14-2) simplify maintenance by including all necessary studs and nuts for quick assembly, while unstudded modules (TS-107.11.110.14-1) offer flexibility for teams that prefer to reuse existing hardware.
3. Recommended Applicable Operating Conditions
These LANSHI 3NB-1600 fluid end parts are engineered to perform reliably across the harshest global drilling and well stimulation environments, aligned with the pump’s 1600 HP rated capacity and 12” stroke design. They are suitable for onshore oil & gas drilling rigs, offshore jack-up and semi-submersible rigs, horizontal drilling operations, deep well drilling (up to 16,000 feet), and hydraulic fracturing sites—all common applications for the LANSHI 3NB-1600 mud pump.
4. Proactive Maintenance & Service Recommendations
To maximize the service life of the LANSHI 3NB-1600 fluid end, minimize downtime, and preserve optimal pump performance, follow these field-proven maintenance protocols—designed to address common failure modes and extend component life. These recommendations are tailored to the specific components in this parts list and align with the LANSHI 3NB-1600’s operational requirements:
Clean liner bushings (TS-107.11.110.18-1) and wear plates (TS-107.11.110.43) every 850 operating hours to remove mud buildup, which can cause misalignment and wear. Use only API-certified lubricants for valve guide bushings to reduce friction and extend service life. Always cross-verify TSC part numbers prior to installation to ensure full compatibility with the LANSHI 3NB-1600 fluid end, and avoid mixing OEM and non-OEM parts, which can cause misalignment and premature failure. Store spare parts in a clean, dry environment to prevent corrosion and damage, especially critical for components like wear plates (TS-107.11.110.43) and valve guide bushings (TS-107.11.110.67) that are prone to surface damage.

5. On-Site Field Failure Repair Cases
Case 1: Wear Plate Gasket Leak Causing Pressure Loss
An onshore drilling rig operating a LANSHI 3NB-1600 pump reported a sudden drop in fluid end pressure, from the rated 7,500 PSI to 5,800 PSI, which halted drilling operations. Inspection revealed a worn wear plate gasket (TS-107.11.110.42), which was leaking drilling mud and causing the pressure loss. Technicians replaced the gasket with a TSC OEM-equivalent unit, torqued the wear plate components to specification, and pressure-tested the system. The pump was restored to full operational capacity within 45 minutes, avoiding over $8,000 in downtime costs.
Case 2: Power Frame Stud Loosening Leading to Fluid End Misalignment
An offshore rig using a LANSHI 3NB-1600 pump experienced abnormal vibration and fluid end misalignment, which threatened to damage the pump’s power frame. Troubleshooting identified four loose power frame studs (TS-107.11.110.17), which had failed to maintain proper torque (900–1750 ft-lbs) under continuous vibration. Technicians retorqued all 12 power frame studs to 1,300 ft-lbs, replaced two studs with stripped threads, and realigned the fluid end. The pump resumed normal operation within 1.5 hours, preventing further damage to the complete fluid end module (TS-107.11.110.00) and other critical pump components.
Case 3: Valve Guide Bushing Wear Causing Erratic Mud Flow
A remote drilling site reported erratic mud flow and increased noise from their LANSHI 3NB-1600 pump, which reduced drilling efficiency by 28%. Inspection found excessive wear in the valve guide bushings (TS-107.11.110.67), which was causing valve misalignment and leakage. Technicians replaced the valve guide bushings and lower valve guide assemblies (TS-107.11.110.52-1), adjusted valve clearances, and tested the pump. The pump’s flow rate and pressure returned to normal within 1 hour, avoiding costly damage to valve seats and preventing unplanned downtime.
