7 Critical Steps to Extend Your Slurry Pump’s Lifespan

Introduction
In mining, downtime costs thousands per hour. A proactive maintenance program for your Warman AH slurry pump can double or triple its service life. Here is the essential checklist used by top maintenance teams.

1. Daily: Monitor Vibration & Temperature

• Bearings should not exceed 70°C (160°F).

• Sudden vibration spikes indicate cavitation or bearing failure.

2. Weekly: Check Gland Water & Packing

• Packing Glands: Should leak slightly (approx. 1 drop/sec) for cooling. Zero leak means burning packing; flooding means excessive wear.

• Gland Water Pressure: Must be higher than pump discharge pressure to prevent slurry ingress.

3. Monthly: Lubrication Analysis

• Check oil levels and color. Milky oil indicates water ingress.

• Grease-lubricated bearings: Follow strict re-greasing intervals (do not over-grease!).

4. Quarterly: Inspect Wear Parts

• Measure impeller and liner clearance.

• Rule of Thumb: Replace when efficiency drops by 10% or clearance doubles. Don’t wait for breakthrough!

5. Alignment Check

• Misalignment is the #1 cause of bearing failure. Re-check laser alignment after any maintenance work.

6. Suction Line Inspection

• Check for air leaks in flanges and valves. Air entry causes cavitation and flow instability.

7. Keep Spares Ready

• Maintain a stock of XingOu A05 impellers, liners, and seals. Waiting for shipping during a breakdown is too expensive.
