1. Product Introduction

Our TSC WWS500 fluid end parts lineup covers all critical components needed to maintain, repair, or overhaul the TSC WWS500 mud pump’s fluid end, organized by function for easy procurement. All parts are fully compatible with the TSC WWS500 model, with precise dimensional consistency for seamless integration, eliminating the risk of mismatches. Key categories include: 1) Complete & Modular Assemblies, ready-to-install units that save 0.6–1.0 hours of assembly time during overhauls; 2) High-Strength Fasteners, heavy-duty options engineered for secure component attachment under pressure; 3) Seals & Gaskets , leak-proof solutions built to withstand harsh drilling environments; 4) Valve & Liner Components, critical for smooth operation. All parts are drop-in compatible, requiring no custom modifications.
2. Functional Specifications
Every TSC WWS500 fluid end part is engineered to meet the operational demands of the TSC WWS500 mud pump, matching or exceeding OEM standards and API 7K criteria. Key details: The TS-FEMWWS500CA Complete Assembly maintains 97.8%+ volumetric efficiency for stable mud delivery, even under maximum operating pressure. Fasteners provide secure torque retention: TS-79AJ2 Studs deliver 4,600 ft-lbs, WWS500-010-02 Studs 4,200 ft-lbs, preventing misalignment and leakage. Seals and gaskets use high-performance FKM materials, ensuring leak-free operation at -5°F to 290°F, resisting degradation from drilling mud, saltwater, and harsh chemicals. All parts undergo 4500 PSI pressure testing for 30 minutes and non-destructive testing (NDT) to ensure durability, meeting API 7K requirements for oilfield equipment. The TS-FEMWWS500CA comes pre-assembled, reducing installation time by 42% compared to assembling components individually.
3. Applicable Operating Conditions
Our TSC WWS500 fluid end parts perform reliably in all environments where the TSC WWS500 mud pump is used, including onshore conventional drilling, shallow to medium well workover, and low-pressure gas drilling. They withstand operating pressures up to 4500 PSI (31.0MPa) and ambient temperatures from -5°F to 105°F, suitable for cold-weather, desert, and coastal operations. Resistant to high-sand drilling mud, saltwater, and drilling chemicals, they prevent corrosion and premature failure. Ideal for Class I, Division 2 hazardous areas, they integrate seamlessly with TSC WWS500 maintenance protocols. We recommend inspecting parts every 150 operating hours (industry best practice) to prevent unplanned failures, suitable for well depths from 1,500 to 10,000 feet.
4. Maintenance & Service Recommendations
To maximize part service life and minimize downtime for TSC WWS500 mud pumps, follow these practical guidelines: 1) Inspect seals and gaskets (TS-200PJH715, R-27, TS-25G18) every 150 operating hours—seal failure causes 58% of TSC WWS500 fluid end issues; replace cracked seals immediately. 2) Torque fasteners regularly: TS-79AJ2 (4,600 ft-lbs), WWS500-010-02 (4,200 ft-lbs) every 110 operating hours. 3) Clean TS-2013547 Valve Guide Bushings every 130 operating hours—mud buildup reduces efficiency by 12% and causes valve jamming. 4) Replace FKM seals every 430 operating hours (sooner if leaking). 5) Store spares in a clean, dry environment (40°F–80°F, ≤60% humidity) to prevent corrosion, especially TS-79AJ2 Studs. 6) Use only OEM-equivalent parts—generic parts increase repair costs by 62% on average. Following these steps extends component life by 58% and reduces maintenance costs by 30%.

5. On-Site Failure Repair Cases
Case 1: Leaking TS-200PJH715 Valve Cover Gaskets Causing Pressure Loss
An onshore rig’s TSC WWS500 pump had a 14% pressure drop and 11% reduced efficiency due to leaking TS-200PJH715 gaskets. Generic gaskets failed after 105 hours. Replacing with our OEM-equivalent gaskets restored leak-free operation, stabilized pressure, and extended gasket life to 580 hours. The repair took 18 minutes, avoiding 2 hours of downtime and $4,500 in lost productivity.
Case 2: Worn TS-1PA217 Liner Clamps Leading to Pump Vibration
A medium well rig’s TSC WWS500 pump had 16% reduced efficiency and vibration from worn TS-1PA217 clamps. Generic clamps failed after 380 hours. Our wear-resistant clamps restored smooth operation, improved efficiency by 15%, and prevented further damage. The repair took 35 minutes, avoiding $6,800 in component costs.
Case 3: Faulty TS-79AJ2 Studs Causing Fluid End Misalignment
A coastal rig’s TSC WWS500 pump shut down unexpectedly due to faulty generic TS-79AJ2 studs. The generic studs failed after 430 hours. Replacing with our OEM-equivalent studs restored alignment, ensured consistent mud delivery, and extended service intervals by 340 hours. The pump was back online in 55 minutes, avoiding $8,000 in downtime costs.
