  • 1/2" BSP port connections for easy plumbing integration
  • 12-volt DC motor operation for standard marine electrical systems
  • Self-priming up to 4 meters (13 feet) vertical lift
  • Heavy-duty construction for reliable performance in demanding conditions

Applications:

  • Bilge pumping for removing water from the boat
  • Deck wash systems for cleaning and maintenance
  • Fresh water circulation and transfer
  • Diesel and oil refueling at dockside
  • General water transfer and circulation systems

The F4B-19's flexible design makes it suitable for both continuous duty and intermittent operation. The pump can be combined with optional accessories including pressure switches for automatic operation, check valves, and complete deck wash kits. The flexible impeller design ensures smooth, pulse-free flow while being gentle on the pumped liquid, making it appropriate for both clean water and light fuel transfer applications.

Easy and fast.

Had the product I needed at a price that couldn't be beat. The shipping was a little high, but not completely out of line, either, and it was still better than other companies who have even MORE ridiculous shipping rates. Will buy from them in the future if they have what I need.

Fast Shipping. Good packaging. Very good pricing. Will shop from again.

quick and easy link to amazon is great!

Perfect so far!

Crazy fast shipping. By far the best price of anywhere. The thule bike rack we ordered was in stock, lowest price, easy checkout process, and the company really appears to run an organized, professional business. Very happy with the level of service. We will definitely make sure to use autoplicity in the future.
