Are these spare parts compatible with both F-1300 and F-1600 mud pumps?

Yes, all parts in this list (Part No.: AH1301021100) are fully compatible with both BOMCO F-1300 and F-1600 mud pumps, meeting BOMCO OE specifications and API 7K standards for interchangeability and performance.

What is the recommended replacement cycle for Piston Rubber (6 1/2L)?

Replace the Piston Rubber (T504-132.00) every 3,000-4,000 operating hours, or sooner if abrasion, cracks, or fluid leakage is detected. Regular replacement prevents piston damage and maintains pump displacement efficiency.

Why is it critical to use genuine BOMCO shear pins?

Genuine shear pins (AH0000060111) are calibrated to API 7K shear strength standards, ensuring precise over-pressure activation. Non-genuine pins may shear prematurely or fail to activate, risking catastrophic pump or pipeline damage.
