2. Product Introduction
The FP-02-01-0044 to FP-02-01-0093 series is a premium aftermarket replacement kit built to match OEM dimensional tolerances and performance specifications for heavy-duty oilfield sand pumps. The lineup includes spherical roller bearings (22230C/C3/W33), AC variable frequency motors, ball cage synchronous cardan shafts, rubber-lined wafer butterfly valves, suction strainers, high-tensile zinc-plated fasteners, and custom flange gaskets. All wetted parts use abrasion-resistant alloy steel and rubber composites, while structural components feature quenched and tempered steel for impact resistance.
Backed by 28+ years of oilfield fluid equipment manufacturing expertise, this lineup delivers exclusive field-proven data: spherical roller bearings withstand 3400 continuous operating hours in abrasive mud without temperature spikes; rubber-lined butterfly valves maintain zero leakage for 2200 pressure cycles; sand pump impeller platens resist abrasion for 2900 operating hours; high-tensile fasteners hold torque without loosening for 4200 vibration hours. Full material traceability and batch pressure testing ensure compliance with API and ASME standards, with performance matching or exceeding OEM original parts.
3. Function Description
3.1 Pump Drive & Bearing System Functions
Bearing caps and 22230C/C3/W33 spherical roller bearings support the sand pump drive shaft, absorbing radial and axial loads from abrasive fluid operation and reducing friction-induced wear. AC variable frequency motors deliver adjustable speed power for optimized mud flow, while ball cage synchronous cardan shafts transmit torque smoothly and compensate for minor shaft misalignment. Drive flanges and adjustment mats ensure precise drive assembly alignment, while health blocks (shaft sleeves) protect drive shafts from abrasion and contamination.
3.2 Fluid Control & Piping Functions
Wafer-type rubber-lined butterfly valves (6-inch, 8-inch, 12-inch) regulate drilling fluid flow with tight shut-off, while suction strainers filter out large solids to prevent pump impeller damage. Flange nipples, suction/discharge short sections, and custom gaskets create sealed piping connections, eliminating fluid leakage. Pressure gauge seats and blind flanges enable system pressure monitoring and pipeline isolation for maintenance.
3.3 Fastening & Protective Functions
Zinc-plated high-strength bolts, nuts, and spring washers provide vibration-resistant connections for flanges and pump assemblies, preventing joint loosening. Cardan shaft guards protect rotating components from debris and enhance rig site safety, while Loctite 243 threadlocker secures fasteners against vibration-induced backing off. Grease nipples enable easy bearing lubrication, extending component service life.
4. Structural Features
• Abrasion-Resistant Wetted Components: Valve seals and strainer screens use wear-resistant EPDM rubber and 316 stainless steel, withstanding 2900 hours of high-solid drilling fluid exposure without degradation.
• Precision Bearing Design: 22230C/C3/W33 bearings feature a C3 internal clearance and W33 lubrication groove, optimized for high-load, low-speed sand pump operation and contamination resistance.
• Leak-Proof Flange Construction: Custom flange gaskets and wafer valve bodies conform to ASME B16.5 standards, creating metal-to-rubber sealed joints that eliminate fluid leakage under 150 PSI working pressure.
• Corrosion-Resistant Fasteners: Zinc-plated M20/M24/M36 nuts and bolts meet ISO 898-1 Class 8.8 standards, resisting rust and corrosion in humid oilfield environments for 4200 operating hours.
• Modular Interchangeability: All parts are fully interchangeable with OEM sand pump components, simplifying inventory management and reducing stock redundancy for maintenance teams.
5. Applicable Operating Conditions
These parts are engineered to perform reliably in the harshest oilfield mud handling environments, adhering to API 8B and ASME safety standards:
• Pressure Parameters: 150 PSI maximum working pressure, intermittent surge pressure up to 200 PSI
• Temperature Range: -30°C (arctic drilling sites) to 100°C (high-temperature mud circulation)
• Fluid Compatibility: Water-based drilling mud, oil-based drilling fluid, high-solid abrasive mud (up to 35% sand content)
• Application Scenarios: Onshore oil drilling rigs, mud circulation systems, well servicing fluid pumps, skid-mounted sand pump units
6. Maintenance & Care Recommendations
6.1 Routine Maintenance Schedule
Lubricate bearings via grease nipples every 300 operating hours, monitoring bearing temperature to ensure it stays below 82°C. Inspect butterfly valve seals and suction strainers every 450 hours, cleaning debris and replacing worn seals immediately. Torque check flange fasteners every 600 hours to maintain clamping force, and replace flange gaskets every 1200 hours to prevent leakage. Calibrate variable frequency motor speed every 800 hours, and inspect cardan shaft alignment every 1000 hours.
6.2 Engineer On-Site Tips & Pitfall Warnings
Always apply Loctite 243 to fastener threads during installation to prevent vibration loosening; never reuse deformed spring washers or worn gaskets, as this causes fluid leakage. Use matched adjustment mats to set shaft alignment within 0.1mm runout tolerance, avoiding uneven bearing wear. Do not mix zinc-plated fasteners with non-coated hardware, and clean suction strainers thoroughly before restarting the pump to avoid solid buildup. Replace bearing caps if cracked or deformed, as this compromises bearing sealing and support.
