Regular maintenance of your Interpump pump is essential to ensure optimal performance and longevity. By adhering to a consistent maintenance schedule, you can prevent common issues and extend the lifespan of your equipment.

Initial Setup and Oil Maintenance

• Pre-Operation Setup: Interpump pumps are shipped with a red transport plug to prevent oil leakage during transit. Before operating the pump, replace this red plug with the provided oil dipstick, which features a level gauge and breather hole.
• Oil Change Schedule:
  • First Oil Change: After the initial 50 hours of operation.
  • Subsequent Oil Changes: Every 500 hours of operation.
  • Recommended Oil: SAE 30.
• Oil Level Checks: Regularly inspect the oil level using the clear gauge or dipstick and top up as necessary.
• Water Contamination: If the oil appears whitish, it indicates water contamination, which can result from excessive seal leaks or condensation in humid environments. Address this promptly to prevent damage.

Seal and Valve Maintenance

• Water Seals:
  • Inspection: Periodically check for signs of wear, such as a drop in pump pressure or water droplets forming under the pump at the junction of the head and crankcase.
  • Replacement: If wear is detected, replace the entire seal set promptly to prevent water ingress into the crankcase, which can damage mechanical components.
• Inlet/Outlet Valves:
  • Signs of Wear: A drop or fluctuation in pressure and unusual vibrations during operation may indicate valve wear.
  • Action: Inspect and replace worn valves to maintain consistent performance.

Storage and Inactivity

• Draining the Pump: If the pump will be inactive for an extended period, especially in environments where temperatures may drop below 0°C, it’s crucial to drain it completely. To do this, disconnect the inlet and outlet pipes and run the pump without water for no more than 10 seconds. This prevents residual water from freezing and causing damage.

By following these maintenance guidelines, you can ensure your Interpump pump operates efficiently and remains reliable over time. For more detailed information and support, visit Interpump Australasia’s maintenance page.
