Fluid End Module Repair
Fluid End modules are subject to high pressure, abrasion, corrosion, and fatigue, which can cause damage and reduce their performance and lifespan. It is important to repair and refurbish fluid end modules regularly to ensure optimal efficiency and safety.
KMS will inspect, clean, replace, and restore the parts that are worn out or damaged on modules. Our standard process includes
Identifying the make and model of the fluid end module. Different types of modules require different repair and refurbishment methods and techniques. This first step is critical to determine the best procedure for your module repair.
Removing the damaged parts, cleaning, and sandblasting for module evaluation. Evaluating the condition of the fluid end modules and identifying any internal damage, such as cracks/indications, washouts, thread damage, or internal surface damage.
Restoring the fluid end modules to their original shape and size by using proprietary welding and machining processes, depending on the extent and type of damage.
Repairing and refurbishing fluid end modules will extend their service life, reduce your overall capital expenditure, and improve the performance and reliability of the mud pumps. KMS is equipped to repair all types of fluid end modules, including one-piece, two-piece, L-shaped, or valve-over-valve.
