Kohree 12V DC Washdown Pump Kit — 7.5 GPM 80 PSI, Self-Priming Marine Kit with 20 ft Hose and On-Demand Switch

This compact kit combines a durable 12V diaphragm pump with a pressure-activated switch, UV-resistant coiled hose, nozzle and fittings to give boats, RVs and outdoor gear a professional rinse without complicated plumbing. Built to resist corrosion and tolerate occasional dry runs, the unit balances powerful flow with quiet, vibration-reduced operation so you can clean decks, fish boxes, anchor chains and hulls efficiently.

How much cleaning power will I really get?

The Kohree pump supplies up to 7.5 gallons per minute and can reach 80 PSI peak pressure, which speeds grime removal compared with lower-flow pumps. That higher flow reduces time spent rinsing large surfaces while the pressure gives the force needed for stuck-on dirt.

• Maximum flow: 7.5 GPM for faster rinsing of decks and gear
• Peak pressure: 80 PSI for tougher residue removal
• Spray reach up to 32.8 ft for extended cleaning coverage

Is it easy to install and operate on a boat or RV?

The kit arrives with the main pump, a 20 ft UV-resistant coiled hose, 1/2" quick-connect fittings, barbed fittings, a seawater filter and Teflon tape so you can get running with minimal extra parts. An automatic on-demand pressure switch energizes the pump only when the spray gun is opened, making operation simple and conserving battery power.

• Complete accessory set included for straightforward mounting and hookup
• On-demand pressure switch: automatic start/stop when trigger is used
• Self-priming capability up to 6 ft of vertical lift for flexible placement

Will it handle saltwater and rough conditions?

The motor is coated with anti-corrosive stoving varnish and the pump’s materials are selected to tolerate both freshwater and saltwater environments. It’s engineered for continuous-duty use under normal workloads and can tolerate brief run-dry events without immediate failure, making it suitable for marine applications.

• Corrosion-resistant motor varnish for marine durability
• Run-dry capable for short periods without immediate damage
• Includes seawater filter to protect pump internals from debris

How quiet and robust is the unit during use?

The Kohree pump is built with a five-chamber diaphragm arrangement and anti-vibration rubber feet for smoother flow and reduced noise. A shock-proof iron plate further stabilizes the assembly so operation stays under typical conversational noise levels while lowering vibration transfer to your vessel or RV.

• 5-chamber diaphragm design for steadier pressure and smoother output
• Anti-vibration feet and iron plate to minimize noise and movement
• Continuous-duty design suitable for repeated cleaning cycles

Who this is for: The Kohree 12V DC Washdown Pump Kit is aimed at boat owners, yacht crews, RV and travel-trailer users, and outdoor enthusiasts who need a rugged, high-flow washdown system without complex installation.
