Gianneschi EXCELSIOR-3 Bronze Hand Pump (Model 01HE3B)
If you need a manual pump that keeps working when the power doesn't, the EXCELSIOR-3 from Gianneschi is built for exactly that job. It's a bronze, double acting, semi-rotary hand pump designed to move a serious amount of liquid with each stroke, roughly 9.2 gallons per minute at 95 feet of head, or about 40 PSI. That kind of output makes it a practical backup for bilge duty, fuel transfer, or even light fire-fighting tasks where a dependable manual option matters.
What sets this pump apart is the build quality. The housing and internal components are fully bronze, including the impeller, so it holds up well against both fresh and salt water without the corrosion issues you'd see in lower-grade materials. The shaft is carbon steel for added strength under repeated use. With 1-1/4 inch inlet and outlet ports, it's sized to handle real volume rather than a trickle, and its performance is tested to EN ISO 9906 standards, so the flow numbers aren't just marketing claims.
This isn't limited to boats, either. While it's a favorite in marine environments for bilge and emergency water removal, the same bronze construction and flow capacity make it a solid choice anywhere a manual, no-power-required pump is useful, from transferring diesel to moving general liquids in industrial or off-grid settings. It's a simple, mechanical solution built to outlast the equipment around it.

Frequently Asked Questions
Q: Can this pump handle liquids other than water?
A: Yes, it's designed for lifting and pushing clear liquids in general, which includes diesel fuel in addition to fresh and sea water.
Q: Does the EXCELSIOR-3 require electricity to operate?
A: No, it's a fully manual, hand operated pump, making it a reliable backup when electrical power isn't available.
Q: How is the flow rate of 9.2 GPM measured?
A: That rate is based on 95 feet of head, equivalent to about 40 PSI, at a pumping speed of 60 cycles per minute.
Q: Is this pump only suitable for marine use?
A: While it's widely used in boats for bilge and fuel transfer, its bronze construction and manual design also suit industrial and general liquid-transfer applications outside marine settings.
Q: What sizes are the inlet and outlet ports?
A: Both the inlet and outlet ports are 1-1/4 inch, allowing for strong throughput per stroke.
