TRUPOW 110V Self-Priming Fuel Transfer Pump — 3.7 GPM, Reversible Switch, Cast-Iron Chamber

TRUPOW's 110V self-priming transfer pump is a compact, reversible fuel pump engineered to move gasoline, diesel and kerosene quickly and safely at up to 3.7 gallons per minute.

This lightweight pump combines a copper-wound motor, explosion-resistant components and a cast-iron sealed pump chamber to deliver dependable on-site fuel transfers. Designed for home garages, boats, farm equipment and light industrial use, the unit accepts standard 1/2" NPT fittings, includes essential connectors, and runs on a household 110V/60Hz supply. Built-in thermal protection, a bypass to prevent backflow and a user-friendly reversible switch make it practical for filling, emptying, or moving liquid fuel with minimal fuss.

How fast and far can this pump move fuel?

The TRUPOW pump moves up to 3.7 gallons per minute and has strong suction and lift capabilities for short- to medium-distance transfers. It balances flow rate with a modest 1/10 HP motor optimized for portable tasks.

• Maximum flow: 3.7 gallons per minute (approx.).
• Max suction length: about 4.9 ft for drawing fuel into the pump.
• Maximum lift: up to 19 ft for pushing fuel vertically.
• Recommended run cycle: about 30 minutes to avoid overheating.

Is it safe to use with different types of fuels?

This pump is approved for low-viscosity petroleum fuels such as gasoline blends (up to E15), diesel blends (up to B20) and kerosene. Safety features reduce ignition risk and protect the motor during demanding use.

• Explosion-resistant components to lower spark risk during transfers.
• Thermal protection that stops the motor if it overheats.
• Built-in bypass valve to prevent reverse flow into the source container.
• Approved for common liquid fuels—avoid thicker fluids or solvents not specified.

How do I install and operate the pump?

Installation is straightforward with 1/2" NPT inlet/discharge ports and included fittings and clamps. A simple reversible switch lets you change pumping direction without repositioning the unit.

• Included: pump unit, sealing gasket, four fittings and four hose clamps.
• Connect hoses to the 1/2" NPT ports and tighten clamps to prevent leaks.
• Plug into a 110V/60Hz outlet; press the switch for forward or reverse pumping.
• Follow the 30-minute recommended run cycle and allow cool-down between extended uses.

What maintenance and durability features should I expect?

TRUPOW constructed this pump with long-term use in mind, featuring a heavy-duty cast-iron sealed chamber and copper motor windings. Routine checks and proper operation extend service life.

• Cast-iron sealed pump chamber resists wear and corrosion from fuel exposure.
• Copper motor windings for efficient, durable electrical performance.
• Thermal cutoff protects the motor during overloads or blocked flow.
• Manufacturer testing and warranty support for issues reported within 24 hours.

Who is this for: The TRUPOW 110V self-priming transfer pump is aimed at DIY mechanics, boat owners, RV and caravan enthusiasts, small farm operators and equipment technicians who need a portable, reversible solution for moving gasoline, diesel or kerosene. It fits situations where a reliable, household-voltage pump is preferred over large, permanent installations—ideal for seasonal use, garage projects and mobile fueling tasks. Always follow local regulations and safety practices when transferring flammable liquids.
