Product Introduction

Our CSF-1600 general frame parts are premium OEM-equivalent components covering the pump’s full structural and auxiliary systems, including rack assemblies, crankshaft and pinion components, crosshead parts, multi-specification seals, high-tensile fasteners, safety valves, air domes, and pressure monitoring hardware. Crafted from forged alloy steel, wear-resistant cast iron, oil/abrasion-resistant elastomers, and corrosion-resistant metal alloys, all parts meet strict API 7K standards for drilling pump equipment, making them the trusted choice for structural repairs, routine maintenance, and full pump overhauls.
Functional Specifications
- Structural Load Bearing: Heavy-duty rack and base assemblies support continuous high-pressure operation, withstanding torsional loads up to 120,000 lbs and maintaining pump alignment under extreme vibration.
- Leak-Free Sealing: Multi-size oil seals, O-rings, and packing rings prevent lubricant and fluid leaks, protecting internal components and maintaining clean rig conditions.
- Power Transmission Stability: Precision crankshaft and pinion assemblies ensure smooth torque transfer, minimizing energy loss and reducing wear on rotating components.
- Safety & Monitoring: JA-3 shearing safety valves, KB-75 air domes, and 60Mpa quake-proof pressure gauges safeguard against overpressure incidents and enable real-time performance monitoring.
- Vibration-Resistant Fastening: High-tensile bolts, nuts, and spring washers maintain tight assembly under harsh operating conditions, preventing loosening and misalignment.
Structural Characteristics
These CSF-1600 frame components feature a rugged, field-optimized design: reinforced welded rack assemblies for maximum structural rigidity, modular crosshead and crankshaft components for easy replacement, precision-machined sealing interfaces for universal fit, and standardized fasteners for simplified installation. The modular design allows partial component replacement instead of full frame overhauls, reducing material waste and repair labor time significantly.
Applicable Operating Conditions
These components are engineered to perform reliably in the most demanding drilling environments: onshore deep-well oil/gas exploration, offshore platform well servicing, directional drilling, geothermal drilling, and high-solid abrasive mud circulation operations. They tolerate extreme temperature fluctuations (-20°F to 220°F), acidic drilling fluids, continuous 60Mpa pressure cycling, high-vibration rig conditions, and prolonged exposure to dust and debris, making them suitable for remote land rigs, offshore vessels, and commercial drilling installations alike.
Maintenance & Servicing Recommendations
To maximize component lifespan and maintain frame integrity, follow these industry-approved protocols: inspect all seals, packing rings, and O-rings every 300 operating hours for wear or leakage, replacing damaged parts immediately; re-torque all bolts, nuts, and stud bolts to OEM-specified values every 450 hours to prevent vibration-induced loosening; inspect rack and base assemblies for cracks or misalignment quarterly; calibrate pressure gauges semi-annually to ensure accurate readings; lubricate crankshaft and crosshead components with API-approved lubricant every 600 hours; and clean strainers and air vent covers regularly to maintain unobstructed fluid and air flow.

Field Failure Repair Case Studies
Case 1: Degraded Oil Seal Causing Lubricant Leakage
A land drilling rig operating a CSF-1600 pump detected lubricant leaks around the crankshaft assembly, traced to a worn two-lip oil seal. Replacing the OEM-matched oil seal and re-sealing the assembly stopped leaks, preventing bearing dry running and extending crankshaft service life.
Case 2: Loose Frame Bolts Causing Structural Misalignment
An offshore well servicing crew reported abnormal pump vibration and misalignment, caused by loose M27 frame bolts that weakened structural stability. Re-torquing the bolts, replacing spring washers, and realigning the rack assembly restored smooth operation, eliminating vibration-related wear.
Case 3: Faulty Pressure Gauge Leading to Unmonitored Pressure Spikes
A remote drilling rig faced an unforeseen pressure anomaly due to a malfunctioning 60Mpa quake-proof pressure gauge. Installing a new gauge and checking the KB-75 air dome restored accurate pressure monitoring, preventing potential overpressure damage to the fluid end assembly.
