Installation Guide

  1. Before installation, apply a suitable grease to the new impeller. This helps with insertion and provides initial lubrication.
  2. Install the impeller into the pump bore, ensuring the blades are bent in the correct direction of rotation.
  3. Once the pump is reassembled, allow it to prime for up to 30 seconds.
  4. Never run the pump dry for more than 30 seconds. Lack of liquid will cause heat and damage the neoprene impeller.
  5. Verify that all suction pipework is airtight to ensure the pump can self-prime effectively.

Troubleshooting & FAQ

Q: How do I know when it's time to replace my impeller?
A: You should replace your impeller if you notice blades are cracked (often about halfway up their height), permanently curved, or have pieces missing.

Q: What causes an impeller to fail prematurely?
A: The most common causes are running the pump dry or cavitation. Signs of dry running include hard, polished, or cracked end faces. If entire blades are missing, it indicates severe dry running. Pieces missing from just the blade tips usually point to cavitation in the system.

Q: What fluids can this impeller handle?
A: This neoprene impeller is designed for pumping fresh water, salt water, and mild chemicals. It is not suitable for pumping oils or fuels, as prolonged contact will cause the neoprene to swell and degrade.

Q: OEM vs. Aftermarket?
A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.

Q: How fast do you ship and how much does it cost?
A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.

Q: What is your warranty and return policy?
A: This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details. Returns are accepted within our standard return window (unused & in original condition); please see our policy page or reach out for instructions.
