Fluid End Manufacturing

CB HYMAC provides fluid end machining for your heavy equipment and industrial machinery in your milling, drilling or threading jobs. Directional drilling critically relies on fluid ends to regulate the fluids being pumped into the well for oil fracking. Because fluid ends play a critical role and perform for consistent regulation, the components only last about several weeks — and in some cases, several days.

We leverage our extensive experience in the oil and gas industry. Over the years, we’ve mastered designing custom fluid ends of any size for any application. Our in-house engineers will work with you to create a fluid end that meets OEM specifications to run at optimal performance. Made from solid blocks of steel, fluid ends require large amounts of machining. Although fluid ends may pose machining challenges, such as raw material scale, varying depths of cut and long tool overhangs, CB HYMAC professionals are trained for the job.

The phases of fluid end manufacturing are:

  1. Cutting and Cubing: The cutting and cubing process involves squaring rough billets and prepares the block for rough machining.
  2. Rough Machining: Rough machining is a phase that optimizes your machine’s operations and provides high metal removal rates.
  3. Finish Machining: The process of finish machining encompasses threading operations.

Our fluid end manufacturers are trained in-house to provide you with the highest-quality manufacturing at cost-effective rates. To learn more about fluid end manufacturing at CB HYMAC, check out our website.

Fluid Analysis


To prevent engine and hydraulics failure, Cleveland Brothers and CB HYMAC offer fluid analysis services to test and analyze your oil and coolant fluids. The wearing of an engine can release particles of metal into an engine’s oil and fluid systems, damaging components in your heavy equipment or industrial machinery.

We recommend using a scheduled oil sampling, or SOS, program to detect problems with your machine’s fluids to avoid expensive repairs and downtime. Collecting machine fluids for analysis is simple:

  1. Request a fluid sample kit from Cleveland Brothers or CB HYMAC.
  2. Collect the fluid — choose either the Oil Valve Probe method or Vacuum Extraction method.
  3. Complete the label included with the kit and send the oil to your local Cleveland Brothers or CB HYMAC location.

Routine fluid analysis can help prevent unexpected downtime. Much like routine doctor’s visits, routine oil and fluid sampling offer early detection of contaminants in your machine’s system – saving you thousands on potential repair costs.
