FMC Pump AL 1122BCD Complete Spare Parts List

1. Product Overview & Core Field Application Value

1.1 Field Pain Point & Equipment Adaptation

Onshore and offshore oilfield operations frequently face unplanned downtime caused by worn crankshaft components, failed rod assemblies, degraded sealing systems, and mismatched pump spare parts. The FMC Pump AL 1122BCD, a high-pressure industrial fluid transfer pump widely deployed in oil and gas exploration, drilling, and production processes, relies entirely on precision-matched internal spare parts to maintain stable cyclic operation. Minor component wear or non-standard part replacement often leads to pressure fluctuation, fluid leakage, vibration overload, and even sudden pump shutdown, severely delaying drilling progress and increasing field operation costs. This full spare parts set tailored for FMC Pump AL 1122BCD solves core field pain points including short part service life, poor interchangeability, and insufficient high-pressure resistance of generic accessories.

1.2 Core Function & Structural Characteristics

The complete spare parts suite for FMC Pump AL 1122BCD covers all core wearable and load-bearing components, including power transmission parts, sealing components, bearing assemblies, fastening accessories, and cylinder piston parts. The core function of these parts is to support the pump’s continuous high-pressure fluid delivery, ensure stable power transmission from the crankshaft to the piston assembly, and achieve zero leakage of internal and external fluid systems. Structurally, all parts adopt integrated precision machining and standardized tolerance design. Power components such as crankshafts and pinion shafts feature reinforced alloy structures to resist torsional deformation, while sealing and gasket parts adopt composite compression-resistant structures to adapt to frequent pressure changes. Modular assembly design enables quick on-site disassembly and replacement, greatly improving maintenance efficiency.

1.3 Applicable Working Conditions

This batch of AL 1122BCD pump spare parts is specially optimized for harsh oilfield working scenarios, fully adapting to onshore conventional oilfields, offshore platform production areas, high-vibration drilling zones, high-temperature deep well operation areas, and high-pressure hazardous process areas. All components can maintain stable performance under long-term mechanical vibration, alternating load impact, and extreme temperature and pressure environments. Sealing accessories and gaskets effectively resist medium corrosion from crude oil and drilling fluid, while load-bearing parts maintain structural stability under long-term cyclic load, avoiding fatigue failure in high-risk working conditions.

1.4 On-Site Engineer Maintenance Suggestions

From on-site operation experience, regular targeted inspection and standardized replacement of AL 1122BCD pump spare parts are key to extending equipment service life. Engineers are recommended to conduct a full inspection of rod bearings, wrist pins, and oil seals every 300 hours of pump operation, check gasket tightness and O-ring sealing performance every 500 hours, and complete a full set of wearable parts replacement after 2000 hours of cumulative operation. During assembly, strictly follow standardized torque parameters to avoid excessive or insufficient fastening force causing component damage or loose connection. In high-temperature and high-vibration working areas, appropriately shorten the inspection cycle of sealing parts and bearing components to prevent sudden failure.

1.5 Standard Certification & Measured Technical Data

All FMC Pump AL 1122BCD spare parts comply with MSDS material safety specifications, EExd explosion-proof standards, UL safety certification, and ASME B18.3 mechanical fastening dimensional standards, ensuring full compliance with international oilfield equipment safety and manufacturing specifications. Field tested measured data verifies reliable performance: the overall working temperature resistance range of parts is -40℃ to 180℃, maximum withstand working pressure reaches 105MPa, standard assembly tightening torque is 45-65N·m, core alloy parts have a Rockwell hardness of HRC 38-42, and the fatigue life of key load-bearing components reaches 1.2 million cyclic operations without structural failure. All materials have complete traceability certificates, and each batch of parts passes dimensional accuracy testing, pressure resistance testing, and fatigue aging testing before delivery.
