Common Concerns Answered
How can I avoid difficulty removing the old impeller?
Ensure you have the appropriate impeller puller tool specifically designed for marine impellers. Proper lubrication of the pump housing and impeller during installation of the new unit also facilitates easier future removal. Avoid forcing the old impeller, which can damage the pump housing.
What if I order the wrong impeller size?
Accurate measurement of the old impeller's diameter, shaft width, and shaft diameter is critical. Cross-reference these dimensions with the product specifications and consider consulting your pump's service manual or contacting our specialists to confirm compatibility before purchase to prevent ordering errors.
What causes premature wear on an impeller?
Premature wear is typically caused by operating the pump without adequate lubrication, often referred to as 'running dry,' or insufficient greasing of the new impeller and pump cavity during installation. Ensure the pump is adequately primed and lubricated with marine-grade grease before initial startup.
