Jabsco 920-0003 - Impeller
The Jabsco 920-0003 Impeller is a crucial component for efficient engine cooling and bilge pumping. Constructed from durable Nitrile rubber, this flexible impeller features 8 blades and a robust 5/8 inch (16mm) brass spline drive shaft hub. It measures 2-9/16 inches wide (65mm) by 2 inches thick (51mm), making it suitable for a variety of demanding applications.
Designed to handle heavily contaminated water, including mixtures with oil or diesel, the Jabsco impeller ensures reliable performance in challenging conditions. Regular replacement of impellers is recommended—at least annually or more frequently depending on engine use. Proper installation can extend the lifespan of the impeller to several years, though a preventative maintenance schedule is advised.
With its ability to manage a broad range of fluids, including oils, emulsions, diesel fuel, and lubricants, the Nitrile impeller is versatile and resilient. It operates effectively within a temperature range of 50°F (10°C) to 180°F (82.2°C). Note that performance may decrease slightly at lower temperatures or with corrosive fluids; flushing with water after use can help prolong its life. Carrying spare impellers is a practical precaution for emergencies. Jabsco impellers are rigorously tested to ensure they meet high standards for reliability and performance.
