Jabsco Rinse Pump f/37045 & 37245 Series Toilets - 12V

The Jabsco Rinse Pump for 37045 and 37245 Series Toilets is a 12V freshwater circulation pump engineered for marine heads on cruising sailboats, center consoles, and cabin cruisers. This self-priming PAR-MAX 4.0 pump delivers 16.3 liters per minute (4.0 GPM) of rinse-water flow, enabling effective bowl cleaning between pump cycles without requiring external pressure tanks or complex plumbing modifications.

Specifications confirm this pump's marine-grade reliability: rated for 12V DC operation at 7.0 amperage with a 15A fuse protection rating, it achieves self-priming to 3.0 meters of lift—essential for installations where the water source sits below the pump intake. The pump runs dry without internal damage, a critical safety feature during extended anchoring or storage when water lines may empty. Compatibility spans the 37245, 37255, and 37275 Jabsco toilet series, and it serves as a verified alternate to OEM part numbers 30631-0092, 30631-1012, and 30631-1092, ensuring correct fit during replacement or retrofit projects.

This pump suits cruising crews and liveaboards who demand reliable freshwater sanitation systems in remote anchorages and coastal waters. Weekend boaters benefit from the low electrical draw and straightforward 12V integration with standard marine electrical systems. The dry-run capability protects against damage during winter layup or when water tanks are drained for maintenance—a practical consideration for owners who winterize systems in northern climates or extend time away from shore facilities.

Jabsco pump systems are industry-standard in the marine sanitation sector, chosen by OEM manufacturers and retrofit technicians for durability in salt-air and condensation-prone environments below deck. This rinse pump integrates seamlessly into existing Jabsco toilet installations and meets the functional demands of vessels ranging from cruising catamarans to offshore trawlers where consistent head operation is non-negotiable.
