LGF3081/LGF3101/LGF3161 Series Drilling Pump Fluid End Spare Parts

LGF3081/LGF3101/LGF3161 Series Drilling Pump Fluid End Spare Parts

1. Product Overview & Core Application Positioning

1.1 Adaptable Equipment & User Segmented Demand

This complete set of accessories and dedicated maintenance tools is exclusively developed and produced for LGF-800 drilling pumps, fully matching LGF3081, LGF3101 and LGF3161 series fluid end equipment. It targets core pain points in on-site drilling operations, including difficult disassembly of aging fluid end components, frequent failure of sealing and piston parts, low efficiency of manual maintenance and unqualified replacement precision. The products serve oilfield drilling teams, equipment maintenance contractors and petroleum engineering technical departments, covering full-cycle demands of daily wear replacement, regular equipment overhaul and on-site rapid fault repair for drilling pump fluid ends.

1.2 Core Value & Authoritative Technical Certification

All wearing parts and maintenance tools are manufactured in strict accordance with API 6A and API 6S petroleum industry standards, with valve assemblies fully complying with API 6# specification for drilling fluid service conditions. Relying on long-term professional oilfield pump accessory manufacturing experience, the products pass 70MPa ultra-high pressure static pressure test and continuous cyclic wear test. Exclusive field verification data shows that the optimized combined sealing structure maintains zero leakage after 8 hours of continuous high-pressure operation, and the service life of customized cylinder liner and piston components is 1.5 times that of conventional ordinary accessories, greatly improving on-site operation stability.

2. Product Introduction & Functional Explanation

2.1 Complete Product Composition

The product portfolio covers two core categories: professional maintenance tools and fluid end vulnerable parts. Maintenance tools include multi-specification sleeves, sockets, extension rods, connectors, cylinder head plug removal tools, stem guide removal tools, cylinder ejector tools, hydraulic valve pullers and PS-II 70MPa manual hydraulic pumps. Fluid end accessories cover central pull rods, multi-type oil seals, cylinder liner seals, bonnet seals, valve springs, API 6# valve assemblies, piston nuts, piston seals, piston rods, cylinder liners, piston rubber parts, clamp assemblies, airbags, gaskets, shear pins and safety valve piston assemblies, forming a one-stop supporting supply system.

2.2 Core Functional Advantages

Dedicated maintenance tools solve the industry pain points of difficult disassembly of rusted and stuck fluid end parts, improving on-site maintenance efficiency and ensuring no damage to original equipment during disassembly. Fluid end wearing parts undertake core functions such as high-pressure drilling fluid sealing, medium circulation control and piston reciprocating operation. Upgraded airbag and capsule components stabilize internal pressure balance of the pump body, while high-precision gaskets and oil seals eliminate slurry leakage and pressure loss caused by seal aging.

3. Structural Features & Applicable Working Conditions

3.1 Optimized Structural Design

All parts adopt integral precision forging and machining process with tight matching tolerance. The double-lip skeleton oil seal structure enhances dust-proof and anti-leakage performance for slurry working conditions; the hydraulic maintenance tool set adopts integrated pressure-bearing structure to adapt to high-strength disassembly operation; the API standard valve assembly adopts anti-wear flow channel design to resist scouring of high-speed solid-containing drilling fluid.

3.2 On-Site Applicable Scenarios

This series of products adapts to harsh oilfield drilling working conditions, resisting slurry scouring, high-load vibration and wide temperature fluctuation. It is widely used for daily maintenance, fault repair and periodic overhaul of LGF-800 drilling pumps in onshore oilfield drilling platforms, meeting long-term continuous high-pressure operation demands of petroleum drilling engineering.

4. Professional Maintenance Specifications & Engineer Practical Suggestions

Follow API standard maintenance specifications for daily equipment management. Inspect oil seal tightness and airbag pressure status daily; check valve spring elasticity and piston rubber wear every 300 operating hours; conduct full disassembly inspection and gasket replacement every 800 operating hours. Professional engineers remind that special hydraulic tools must be used for disassembly of cylinder head and stem guide parts to avoid artificial damage caused by violent disassembly. Replace shear pins and safety valve components regularly to ensure pump body safety protection performance.

We supply the following spare parts:

5. On-Site Fault Maintenance Cases

Case 1: Tarim Oilfield LGF-800 Pump Seal Leakage Fault

The LGF-800 drilling pump operated under 52MPa drilling load for 5 months, with continuous slurry leakage at the fluid end. After replacing LGF3081-04.18 double lip oil seal and cylinder liner seal, the equipment operated continuously for 72 hours without leakage, and the pump body working pressure remained stable. The on-site team verified that the upgraded seal parts have excellent anti-scouring performance.

Case 2: Daqing Oilfield LGF3101 Pump Valve Assembly Failure

The drilling pump had insufficient discharge pressure and slow reset of valve body under rated load due to aging API 6# valve assembly and fatigue spring. After replacing matched valve assembly and valve spring, the outlet pressure returned to standard rated value, and the valve opening and closing response was sensitive and stable.

Case 3: Shengli Oilfield LGF3081 Pump Airbag Pressure Instability

The KB-45 airbag failed after long-term vibration operation, resulting in unstable internal pressure of the pump body and fluctuating drilling fluid delivery. After replacing LGF3081-27.03.00 exhaust airbag and capsule accessories, the pressure balance system returned to normal, and the equipment achieved stable continuous drilling operation.

Case 4: Changqing Oilfield LGF3161 Fluid End Disassembly Difficulty

The aging cylinder head and stem guide were severely stuck and unable to be disassembled manually. After adopting supporting special removal tools and hydraulic valve puller for construction, the disassembly operation was completed efficiently without any damage to original equipment, greatly shortening on-site maintenance downtime.
