MARCO
Pumps
Electric pumps made in Italy by MARCO since 1970: self-priming gear, vane, impeller and electronic pressure pumps for marine, industrial, mobile and defense applications.
Water, diesel, oil and coolant have to be moved wherever there is an engine or a machine. MARCO has been building the electric pumps that do this work since 1970, in its own plant in Castenedolo, near Brescia in northern Italy, and today exports to more than 80 countries. The same pumps are installed on boats of every size, on paving, sweeping and construction machines, on race and special vehicles, on military vehicles and vessels, in commercial fryers and kitchens, and in cooling loops.
Engineers outside the boatyard choose them for the same reasons boat builders do. They run on 12 V or 24 V DC, with selected versions on 110 V or 230 V AC; they are compact and self-priming; they are built in corrosion-resistant ABS, nickel-plated brass, bronze and stainless steel; and the electronic models control their own speed and protect themselves when they run dry.
On board, compact submersible pumps wait in the bilge for the water to rise, started by a mercury-free float switch, and self-priming impeller pumps draw bilge, grey water or ballast from further away. Electronic pressure pumps read the line pressure and adjust their speed, so the shower stays steady and most installations need no accumulator tank; the same technology drives deck-wash kits.
Bronze-gear pumps move diesel and antifreeze, dedicated versions handle lubricating oil, and electronic models switch between a fast diesel setting and a slow oil setting from a small control panel. Ready-made kits and fixed systems turn an engine, generator or gearbox oil change into a clean, closed-circuit job, and vane pumps take care of refueling, on a boat or on a machine.
Why MARCO pumps
- Designed and built in Italy by a pump maker with over 50 years of experience

Choosing the right pump comes down to fluid, voltage, flow and pressure. The catalog below lists part numbers and data for every voltage; Mate USA or your local distributor can confirm the current data sheet before you specify an installation.

Frequently asked questions
Where can I buy MARCO pumps in the USA?
Mate USA distributes MARCO pumps through authorized distributors across the United States and Canada. Use Distributor Search, browse by region, or contact Mate USA.
Which pump should I use for fresh water on board?
Electronic UP/E pumps such as UP3/E or UP6/E are the usual choice: self-priming and automatic, with built-in check valves and electronic pressure control, typically without an accumulator tank. Exact flow and pressure are in the catalog.
Can one pump transfer both diesel and oil?
Some can. Electronic UP-E-BR pumps ship in a high-speed diesel setting and switch to low speed for oils through the SCS panel. Dedicated UP/OIL pumps and reversible OCK kits are also available.
Where do I find pump specifications and model codes?
Download the Pumps & Signal Horns catalog for models (including UP3, UP12, M164-series part numbers), flow rates and electrical data, then confirm the latest sheet with Mate USA.
Can MARCO pumps be used outside boats, e.g. on vehicles or industrial equipment?
Yes. The same 12/24 V DC and AC pump families are installed on construction and sweeping machinery, special and defense vehicles, food equipment and cooling systems. Confirm fluid compatibility and duty cycle for your installation with Mate USA.
