VierKate cordless fuel transfer pump 5 GPM — Bare tool compatible with DeWalt 20V & Milwaukee 18V, auto-stop + hand nozzle, 51" ho

The VierKate 5GPM Cordless Fuel Transfer Pump is a battery-powered, vertical-operated gas can pump that combines an automatic shutoff with a manual hand nozzle for safe, fast transfers of gasoline, diesel, oil, or water.

Designed for mechanics, landscapers, boaters, and homeowners who need portable refueling or fluid transfer, this bare-tool pump accepts common DeWalt 20V and Milwaukee 18V batteries, and includes 12V battery clamps for on-site use. With a 5 GPM (18.9 L/min) flow rate, 51" discharge hose, and four gas can adapters, it balances speed, versatility, and spill prevention in a compact package.

How does the auto-stop and manual nozzle work together to prevent spills?

The VierKate pump integrates a sensitive auto-stop sensor with a robust manual hand nozzle so you can choose automatic shutoff or hands-on control. The sensor stops flow when the receiving container is full, while the manual nozzle lets you continue or interrupt transfer instantly for variable fills.

• Auto-stop sensor detects full container and cuts flow to avoid overflow
• Sturdy hand nozzle offers immediate start/stop control for partial fills
• Rubber sealing ring added inside pipe to reduce leakage and drips

What power options does the pump offer for portability and jobsite use?

Power is flexible: accept DeWalt 20V and Milwaukee 18V Li-ion batteries for cordless convenience, or attach the included 12V battery clamps when a battery isn't available. This lets you run the pump from common tool batteries or a vehicle battery for roadside, farm, or remote work.

• Compatible with DeWalt 20V and Milwaukee 18V batteries (batteries sold separately)
• 12V battery clamps included for direct vehicle or auxiliary battery power
• High-speed 16,500 rpm motor designed for consistent performance under battery power

How quickly and for which fluids can I transfer using this pump?

At up to 5 gallons per minute (about 18.9 L/min), the VierKate pump moves fuel and other liquids faster than manual siphoning or hand pumps. The unit is suitable for gasoline, diesel, light oil, and water, making it useful from small mowers to larger equipment tanks.

• Top flow rate: 5 GPM (18.9 L/min) for rapid refills
• Suitable for gasoline, diesel, oil, and water (avoid incompatible chemicals)
• 16500 rpm motor optimized for steady high-speed transfer

What features make setup and operation user-friendly?

The vertical operating layout keeps the battery and start button visible and accessible, eliminating the need to crouch while attaching batteries or monitoring operation. The single soft rubber power key with LED offers clear tactile feedback and status indication, and the pump includes multiple adapters and hoses for common fuel cans.

• Vertical design positions battery and control button for easy access
• Single soft rubber key with LED indicator for simple on/off feedback
• Four gas can adapters, 23" intake hose and 51" discharge hose for varied applications

Who is this for? The VierKate 5GPM Cordless Fuel Transfer Pump is aimed at professionals and DIYers who need a portable, reliable way to move fuel and liquids quickly without mess: landscapers topping off mowers, mechanics servicing fleets, boat owners refueling onboard tanks, farmers transferring diesel, and anyone who prefers cordless convenience with auto-shutoff safety. Note: batteries are not included; follow local fuel-handling and safety regulations when using the pump.
