Are these components compatible with both BOMCO F-1300 and F-1600 mud pumps?

Yes, all parts are engineered to fit both models, adhering to BOMCO OE specifications and API 7K standards. This ensures full interchangeability and seamless integration with the piston/liner wash system of either mud pump.

What type of flushing fluid is recommended for this system?

Use clean, neutral water or low-viscosity industrial flushing fluid (pH 6.5-8.5) to avoid corrosion of brass/steel components. Avoid acidic or alkaline fluids, as they degrade seals and damage metal parts, per BOMCO maintenance guidelines.

How often should the centrifugal pump be maintained?

Inspect the pump monthly for impeller clogging and leaks. Clean the impeller every 3 months, and replace the pump every 18 months (or 5000 operating hours) to ensure reliable performance, aligning with API 7K maintenance requirements.
