How to determine when to replace F-1600/F-1300 pump liners?

Replace when inner diameter wear exceeds 0.5mm, or if leakage occurs. For high-abrasion mud (solids >5%), replace every 4,000 hours; standard conditions allow 8,000 hours (per API 16A guidelines).

What’s the difference between PU and Viton pistons for these pumps?

PU pistons (e.g., 107.114.00) offer cost-effectiveness for standard mud; Viton pistons (e.g., 107.119.00) resist high temperatures (up to 200℃) and chemicals, ideal for acidic or high-temperature mud.

How to prevent ring joint seal (7602-0661-11) leakage?

Ensure flange alignment (±0.05mm tolerance), clean sealing surfaces, and use compatible thread sealant. Retighten bolts after initial 10 hours of operation and inspect monthly for corrosion.
