Introduction
The TSC OILWELL A-1100-PT pump is a high-performance triplex single-acting mud pump, specifically engineered for medium-pressure oil, gas, and mining drilling operations. With a liner size specification of 7-1/2×10, rated power of 1100 horsepower (hp), maximum operating pressure of 4,500 psi, and a stroke length of 10 inches, this pump delivers consistent fluid circulation with a maximum strokes per minute (spm) of 145 and variable volume per stroke based on liner size (ranging from 1.5 gallons per stroke for 4M liners to 5.7 gallons per stroke for 7 1/2″ liners).
Structural Features
Our TSC OILWELL A-1100-PT pump parts are engineered to match the pump’s original structural design—focused on durability, easy maintenance, and seamless interchangeability, while addressing common pain points like debris-related damage and vibration fatigue. Key structural features include:
- 100% Interchangeability: All components are fully interchangeable with OEM parts, including exact TSC part numbers, reducing inventory costs and simplifying replacement. Many of our liners (e.g., TS-0289-40HP, TS-0289-50HP) are also compatible with the TSC OILWELL A-850-PT pump, adding versatility to your parts inventory and reducing storage costs.
- Abrasion & Corrosion Resistance: Critical components undergo advanced surface treatment (nitriding and chrome plating) to resist wear from solid particles in drilling fluid and corrosion from saltwater (for offshore use) or chemical additives. Our liners have a hardness rating of 58-63 HRC, ensuring resistance to abrasive wear in high-solids environments, while valve seats feature precision machining for a tight fit and extended service life.
Applicable Working Conditions
Our TSC OILWELL A-1100-PT pump parts are built to perform reliably in the most demanding medium-pressure drilling environments, compatible with the pump’s design for oil, gas, and mining applications. Key applicable working conditions include:
- Onshore Oil & Gas Drilling: Ideal for onshore oil and gas wells requiring consistent fluid circulation, including vertical, horizontal, and directional drilling in desert, mountainous, and remote areas. Capable of handling high-temperature conditions (up to 140°C) and abrasive drilling fluid, making it suitable for small to medium-sized wells.
- Offshore Oil & Gas Drilling: Suitable for offshore wells with moderate pressure requirements (up to 4,500 psi), where saltwater exposure is common. Our corrosion-resistant parts protect against marine environments, while vibration-resistant designs withstand rig movement and harsh weather conditions.
Maintenance & Care Recommendations
Proper maintenance of TSC OILWELL A-1100-PT pump parts is essential to extend service life, avoid costly downtime, and ensure optimal pump performance. Following a preventive maintenance approach—focused on daily, weekly, and monthly checks—helps eliminate hidden risks before they lead to failures, which can cost $3,000 per hour or more in downtime. Below are practical, easy-to-follow guidelines tailored to the A-1100-PT’s design:
- Weekly Maintenance: Clean liners and valves to remove sediment buildup, which can cause abrasion and reduce efficiency. Check the tightness of piston nuts (TM-NUT) and rod clamps (TMA17-03-08), and lubricate moving parts with high-quality, high-pressure lubricating oil (as recommended by OEM) every 400 operating hours. Inspect the TMA14-SEALKIT seal set for signs of wear or leakage, as seal failure can lead to costly fluid end damage.
- Monthly Checks: Inspect extension rod seals (TS-20-100-015) and baffles (TS-204-0668) for wear, and replace if leaks are detected. Test valve springs (TS-5710-115, TS-5710-115L) for fatigue, and replace if they fail to maintain proper tension. Check the TS-10300181 fluid end module for cracks or corrosion, and retighten the TMA17-STUDSET studs & nuts set to ensure a secure fit. Also, check the pump’s safety valve for proper operation to prevent overpressure, which can damage critical components.

On-Site Fault Repair Cases
Below are three real-world cases of TSC OILWELL A-1100-PT pump failures, resolved using our OEM-compatible parts—demonstrating how our products solve common operational issues, minimize downtime, and save costs for drilling teams:
Case 1: Liner Gasket Leakage & Pressure Loss
Scenario: An onshore drilling team reported fluid leakage from the liner area, reducing operating pressure by 22% and forcing frequent shutdowns. Downtime was costing the team $1,000 per hour.
Diagnosis: Worn G-754* liner gaskets (marked for A-1100-PT compatibility) were failing to seal under operating pressure (3,800 psi), causing leakage and reduced efficiency.
Solution: Replaced the worn G-754* gaskets with our OEM-compatible parts. After installation, leakage was eliminated, and the pump regained full pressure capacity, reducing downtime by 100% and saving the team over $8,000 in lost productivity.
Case 2: Valve Malfunction & Backflow
Scenario: A mining exploration team faced frequent backflow and pressure fluctuations, leading to inefficient drilling and increased wear on other components.
Diagnosis: The TS-7-EEF valve and TS-7-DDB1 valve seat were worn, preventing proper closure, while the TS-5710-115 spring was fatigued—debris buildup had accelerated component wear.
Solution: Replaced the valve, valve seat, and spring with our OEM-compatible parts. Backflow was eliminated, pressure fluctuations stabilized, and the pump’s efficiency improved by 16%, allowing the team to meet project deadlines and reduce maintenance costs by $3,000 per month.
Case 3: Fluid End Module Seal Failure
Scenario: An offshore drilling team faced severe leakage from the fluid end module, leading to damage to adjacent components and a complete pump shutdown. Downtime was costing the team $1,600 per hour.
Diagnosis: The TMA14-SEALKIT seal set was worn, and the TMA17-STUDSET studs & nuts set had loosened due to vibration, causing the TS-10300181 fluid end module to leak.
Solution: Replaced the TMA14-SEALKIT seal set and retightened the TMA17-STUDSET studs & nuts set with our OEM-compatible parts. The leakage was stopped, and the fluid end module regained structural integrity, allowing the pump to resume operation within 2 hours and saving the team over $3,200 in lost productivity.
