Jabsco 777-0001 Dependable Self-Priming Performance in a Compact Bronze Pump
The Jabsco 777-0001 is a bronze pedestal-mounted flexible impeller pump built for everyday transfer, washdown, and circulation work. Its neoprene impeller and 1" lip type seal are matched to a bare-shaft pedestal body, so it drops easily into an existing drive setup without needing a dedicated motor. Made from marine-quality bronze and stainless steel, the housing resists corrosion and handles both soft and hard solids without clogging, which makes it a good fit for jobs where the pumped liquid isn't always perfectly clean.
What sets this pump apart is its priming ability. It can self-prime from dry up to 10 feet and pull a suction lift of up to 22 feet once wetted, provided the suction line stays airtight. Rated for roughly 23 to 26 gallons per minute at 1750 RPM, it can run in either rotational direction and won't airlock, giving installers flexibility when routing plumbing on a boat, dock, or industrial skid. The impeller itself is well suited to water and other general-purpose liquids, with a working temperature range that covers most everyday pumping conditions.
Serviceability is another strong point. The 777-0001 uses replaceable cams, end covers, and wearplates, so a worn pump doesn't need to be replaced outright — most wear items can be swapped out to extend the unit's working life. This makes it a practical choice for anyone who wants a pump that's easy to maintain long-term rather than a disposable component.

Frequently Asked Questions
Q: Can the Jabsco 777-0001 run without liquid in the line?
A: No. This pump relies on the liquid being pumped for internal lubrication, so it should never run dry for more than 30 seconds, as this can damage the impeller and other internal components.
Q: Does the 777-0001 come with a motor included?
A: No. It's a bare shafted pedestal pump end, meaning it's designed to be driven by a separate motor or existing drive system rather than including one.
Q: Can this pump be mounted in different positions?
A: Yes. The 777-0001 can be mounted in any position, and the direction of the shaft rotation determines which port serves as intake and which serves as discharge.
Q: What kind of liquids is the neoprene impeller best suited for?
A: The neoprene impeller is intended for water and general-purpose liquids, making it a solid choice for washdown, circulation, and general transfer tasks rather than aggressive chemicals or fuels.
Q: How do I know when the impeller or seal needs replacing?
A: Reduced flow, unusual noise, or visible wear on the cam, wearplate, or seal are common signs. Because these parts are replaceable, a repair kit can typically restore the pump without replacing the entire unit.
