Gianneschi EXCELSIOR 2-GB Hand Pump (Model EXCELSIOR-2-GB / Catalog 01HE2GB)
If you need a rugged, no-fuss way to move liquid without relying on electricity or an engine, the Gianneschi EXCELSIOR 2-GB is built for exactly that job. It's a double acting semi-rotary hand pump with a cast iron body and bronze internal components, designed to deliver consistent flow whether you're pulling fresh water, sea water, or another clear liquid from one point to another. The 1 inch by 1 inch inlet and discharge ports keep plumbing straightforward, and because it's close coupled and rated in accordance with EN ISO 9906, you get performance numbers you can actually plan around rather than vague estimates.
What makes this pump useful across so many settings is its simplicity. There's no motor to maintain, no wiring to troubleshoot, and no fuel to keep on hand. A firm, steady stroke on the handle is all it takes to move liquid at up to 6.3 gallons per minute against a 95 foot head, or roughly 40 PSI. That kind of output puts it in a practical middle ground: strong enough for demanding transfer jobs, yet simple enough to install as a manual backup for critical systems where power isn't guaranteed.
While it's a familiar choice on boats for tasks like bilge transfer or freshwater handling, the EXCELSIOR 2-GB isn't limited to marine use. Its cast iron and bronze construction holds up well in general industrial, agricultural, and utility settings wherever clear liquids need to be moved reliably by hand. Anyone looking for a dependable manual pump that doesn't cut corners on build quality will find it does its job with very little drama.
