Can F-1300 and F-1600 components be interchanged?

Only parts with the same part number (e.g., Key AH1301020301) are interchangeable. Different part numbers (e.g., Pinion shaft) are not, as they are tailored to each pump’s structural specifications.

What is the recommended maintenance cycle for these components?

For high-load drilling, inspect sealing parts monthly and replace wear rings/oil seals every 6 months; bearings and pinion shafts should be inspected quarterly and replaced if there is deformation or excessive wear.

How to confirm component authenticity?

Authentic parts have clear, standardized part numbers (consistent with this guide) and meet GB/T 1231 (bolt torque) and GB93 (washer standard) specifications. Avoid non-standard parts to prevent pump damage.
