How to choose the correct liner gasket for my mud pump liner size?

Select a gasket that matches the liner size (e.g., 7″ liner uses P/N 07923285, 5-1/2″ liner uses P/N 29303U/7211005) and pump model. Ensure the gasket material is compatible with your mud type (urethane for high pressure, compressed fiber for standard use) and check the manufacturer’s P/N cross-reference to avoid mismatches, which cause leakage and component damage.

2

What is the difference between single duro and dual duro mud pump pistons?

Single duro pistons (e.g., P/N 85BSD) have a single rubber/seal material, suitable for standard-temperature (up to 300°F/149°C) and medium-pressure operations. Dual duro pistons have two different wear-resistant materials, offering better sealing and durability in harsh conditions (high temperature, abrasive mud) and extending service life by 30%-50% compared to single duro models. Choose based on your drilling mud temperature and pressure.

3

How often should API 7 mud pump valves be inspected and replaced?

Inspect API 7 valves (e.g., P/N 1318058, 60155042) monthly for insert wear, seat scratches, and leakage. Replace valves every 1000-1500 operating hours, or immediately if you notice reduced pump flow, abnormal noise, or visible damage. For harsh conditions (abrasive mud), shorten inspection intervals to 2 weeks to prevent sudden valve failure.
