Detailed Product Introduction
This NOV 200T-5 plunger pump parts collection is split into two mission-critical sections: power end components and fluid end components. The power end lineup includes crankshafts, roller bearings, crossheads, connecting rod bushings, intermediate rod wipers, and crankshaft seals, all cross-referenced to original NOV part numbers for exact fit. The fluid end section features 2.625” ceramic plungers, Kevlar packing sets, spherical suction/discharge valves, stuffing box components, valve covers, and flange gaskets, built to handle abrasive drilling mud and high-pressure fluid flow.
Each component is manufactured to match the 200T-5’s 5-inch stroke and 200 HP rated power, ensuring seamless drop-in installation with zero modifications required. The catalog prioritizes high-wear, high-failure parts that endure constant friction, pressure, and exposure to drilling fluids, supporting both minor on-site repairs and full pump refurbishments.
Functional Performance & Value Highlights
- Stable High-Pressure Performance: Precision-machined valves and Kevlar packing maintain consistent pressure up to 5,000 PSI, eliminating pressure drops and fluid leakage during pumping operations.
- Minimize Rig Downtime: OEM-matched components cut repair and overhaul time by 65%, keeping mud pumping and fluid transfer operations on schedule.
- Extended Wear Life: Ceramic plungers and heavy-duty roller bearings withstand up to 40,000 operating hours, reducing replacement frequency and long-term maintenance costs.
- Perfect Mechanical Alignment: Exact OEM tolerances ensure proper crosshead, connecting rod, and crankshaft alignment, preventing premature bearing failure and mechanical wear.
Structural & Engineering Features
- NOV 200T-5 Exact Drop-In Fit: All components machined to OEM dimensions for seamless installation, no custom machining or adjustment needed.
- High-Strength Material Construction: Forged steel crankshafts, ceramic-coated plungers, Kevlar packing, and heat-treated bushings resist pressure, abrasion, and corrosion.
- API 674 Compliance: Every part meets strict API standards for reciprocating plunger pumps, ensuring safety and reliability in high-pressure operations.
- Modular Assembly Design: Pre-matched stuffing box kits and valve assemblies streamline repairs, reducing part sourcing time for maintenance crews.
Applicable Operating Conditions
These NOV 200T-5 plunger pump parts are built for demanding oilfield pumping environments where high-pressure fluid handling is critical, including:
Drilling mud circulation and high-pressure fluid transfer
Well servicing, cementing, and fracturing operations
Continuous-duty 200T-5 pump operation at up to 400 RPM
Harsh conditions with abrasive drilling mud, high vibration, and extreme pressure
- API 674 compliant reciprocating plunger pump systems
Professional Maintenance & Troubleshooting Recommendations
- Fluid End Seal Inspection: Check plunger packing and stuffing box seals for wear every 1,000 operating hours; replace worn components immediately to prevent high-pressure leaks.
- Power End Lubrication: Lubricate crankshaft bearings and crosshead bushings per OEM specifications, inspecting for noise or play monthly to catch early wear.
- Valve Maintenance: Inspect spherical suction/discharge valves for pitting or damage every 2,000 hours; replace valves and springs to maintain proper fluid flow and pressure.
- Plunger Care: Check ceramic plungers for scoring or cracks regularly; damaged plungers will accelerate packing wear and cause leakage.
- Scheduled Overhaul Intervals: Overhaul the power end and fluid end every 30,000 operating hours to prevent catastrophic pump failure mid-operation.

Field Plunger Pump Fault Repair Cases
Case 1: 200T-5 Plunger Packing Leakage
A NOV 200T-5 pump experienced severe high-pressure mud leakage from the plunger stuffing box due to worn Kevlar packing. Replacing the 342-753 packing set and matching gland eliminated leaks, restoring full 3,000 PSI pumping pressure.
Case 2: Crosshead Bushing Wear
Excessive vibration and noise developed in the power end due to worn 1716012 connecting rod bushings. Installing new OEM bushings and realigning the crosshead fixed the issue, restoring smooth pump operation and reducing mechanical wear.
Case 3: Discharge Valve Failure
The 200T-5 pump lost discharge pressure due to a faulty 179302225W spherical discharge valve. Replacing the valve and matching spring restored proper fluid flow, bringing the pump back to full operational capacity.
Frequently Asked Questions (FAQ)
| Question | Answer |
