What Parts of a Reciprocating Slurry Pump Require the Most Maintenance?

Reciprocating slurry pumps are vital in diverse industries, from mining to wastewater treatment. Proper maintenance is critical to ensure their efficiency and longevity. Here’s a deep dive into the parts of a reciprocating slurry pump that require the most attention.

Essential Maintenance Parts of Reciprocating Slurry Pumps

1. Check the Belts

When to Check Belt Tension

If your slurry pumps operate with belts, ensure you check the tension at least quarterly. Belts that are too tight can damage motor bearings, while loose belts can lead to slippage and sheave damage. Using the Gates tension tester can help identify loose belts by the flapping sound they make. Additionally, SHANGLISHI and manuals from TB Woods can offer valuable guidelines for maintenance.

2. Monitor and Change the Oil

When to Change the Pump Oil

Periodically check oil for contamination by water or other products. Properly functioning seals can prevent premature bearing and motor failures. Water presence can turn the oil milky, indicating potential sealing issues. Incorporate moisture sensors to detect excessive water levels early.

3. Regularly Inspect the Impeller

For optimal performance, maintain proper impeller clearance by consulting the pump’s manual. Inspect the impeller and other wetted parts for excessive wear, which can impact performance. Wear can result from abrasive materials or operating the pump outside its design curve.

4. Evaluate Pump Requirements

Ensure the pump is still suitable for your current system demands. Processes may vary over time, requiring re-evaluation of pump specifications.

5. Temperature Checking

Importance of Monitoring Temperature

Temperature sensors protect the motor by shutting down the pump when it overheats. Regularly monitor bearing temperatures, especially with horizontal and cantilever pumps. Weekly checks using a temperature gun can prevent issues before they require costly repairs. Cobearings typically run between 140-170 F, but never exceed 200 F.

6. Bearing Vibration Analysis

Use vibration equipment to detect bearing failures early. Engage a qualified technician for precise vibration analysis, which significantly improves pump performance and longevity. Refer to industry-standard vibration guidelines for specific pump types. For detailed advice, consult with Hevvy/Toyo engineering.
