We focus on supplying cost-effective, durable parts that directly address the daily wear and tear of pumps in oilfield operations, ensuring each component contributes to the stable operation of the entire system.

Function Description

Each spare part is designed to target specific functions and solve practical operational pain points: Pump head-FJ X01175001 is the core working component of the pump, responsible for generating pressure to transport drilling fluid and slurry, solving the problem of insufficient pumping force and slurry transportation inefficiency. Motor W31710023 provides stable power for the pump, ensuring the pump operates at the rated speed of 1480 rpm, solving the problem of power shortage and unstable operation. Shield X01173022 protects the internal components of the pump from slurry erosion and external impact, extending the service life of the pump. Pump coupling X01173023 and Telelink X01171003 ensure smooth power transmission between the motor and the pump shaft, solving the problem of power loss and jamming. Fasteners like Bolt W01002221(M20×85) and Nut M20 W03012020 securely fix the pump components, preventing loosening caused by high vibration during operation. Imported rubber pad 8” W42711540 and Outlet Rubber Pad 6” W42711530 reduce vibration, protect the pump body and pipelines, and enhance the sealing performance of the inlet and outlet. Keys W08021921 and W08021920 transmit power between the coupling and the shaft, ensuring seamless power transfer.

Structural Features

Our spare parts are designed with robust structures to adapt to the harsh working environments of oilfield pumps: Pump head-FJ X01175001 is made of high-strength wear-resistant alloy, with precision machining to ensure smooth inner surface, reducing slurry resistance and wear, and its thickened structure enhances impact resistance. Motor W31710023 adopts a cast iron shell with high-temperature resistance and corrosion resistance, with a sealed structure to prevent dust and slurry intrusion, and a built-in heat dissipation system to avoid overheating. Shield X01173022 is made of carbon steel with anti-corrosion coating, which is lightweight and durable, effectively isolating slurry and external damage. Fasteners are made of heat-treated alloy steel, complying with GB/T5782-2000 and updated spring washer standards, with surface galvanization treatment to prevent rust and corrosion. Imported rubber pads are made of high-quality nitrile rubber, with excellent elasticity and corrosion resistance, able to withstand the erosion of drilling fluid and slurry. Coupling pin sleeve X01173033 is made of wear-resistant steel, with precise size to ensure tight connection and smooth power transmission, avoiding jamming.

Applicable Working Conditions

Maintenance and Care Suggestions

To extend the service life of spare parts and ensure the stable operation of FJ series self-priming pumps, our engineers with 28+ years of on-site oilfield maintenance experience provide practical tips (with avoidable pitfalls, based on real maintenance experience):

• Core Components: Check Pump head-FJ X01175001 every 80 working hours for wear and leakage; replace if wear exceeds 0.15mm or leakage occurs. Clean the pump head regularly to remove slurry deposits—blockages can increase pump load and shorten service life by 3,400 hours. Avoid hitting the pump head with heavy tools, as this can cause cracks and damage.

• Motor & Transmission Parts: Inspect Motor W31710023 every 70 working hours for temperature, noise, and power output; replace if temperature exceeds 85℃ or power drops by more than 5kW. Check Pump coupling X01173023 and Key C18×105 W08021921 every 90 working hours for wear and deformation; add lubricating grease every 100 working hours to ensure smooth power transmission. Avoid over-tightening the coupling, as this can cause key damage.

• Seals & Rubber Pads: Check W42711540 and W42711530 rubber pads every 60 working hours for aging and damage; replace if cracks or hardening are found. Clean the rubber pad contact surface before installation—slurry or debris on the surface can cause leakage. Avoid exposing rubber pads to direct sunlight, as this accelerates aging.

• Fasteners: Check Bolt W01002221(M20×85), Nut M20 W03012020, and Bolt M10×10 W01042897 every 85 working hours for tightness and wear; replace if thread damage occurs. Always use matching spring pads and flat pads—non-standard washers reduce fastening force and cause component loosening, which can lead to pump vibration and damage. Note that GB/T93-1987 has been replaced by updated standards, and our fasteners comply with the latest requirements.

• General Maintenance: Establish a maintenance log to record part replacement times and operational status. Follow API 682 (4th edition) and relevant national standards (GB/T5782-2000, updated spring washer standards) for regular equipment inspection, and use only matching FJ series spare parts to avoid system damage caused by mismatched components. Store spare parts in a dry, clean environment to prevent corrosion and slurry contamination, and avoid placing heavy objects on rubber pads to prevent deformation.
