BF-3 Manual Hand Siphon Pumps Oil Gasoline Liquid Transfer Refuel Hose Sucker
Type: Liquid Transfer Pump
Common Names: Hose siphon, jiggler siphon, hand pump, transfer pump, sucker pump.
Key Components:
Pump Bulb/Ball: A squeezable primer bulb, usually made of rubber or PVC, that creates the suction to start the flow.
Hoses/Tubes:
Dip Tube (Inlet Hose): The longer, rigid tube that goes into the source container (e.g., the gas can). Often has a filter screen.
Outlet Hose: The shorter, flexible tube that the liquid flows out of into your destination (e.g., the vehicle's tank).
Check Valves: Internal one-way valves that ensure liquid flows in only one direction, from the source to the destination.
Materials: Typically made from plastics (like PP) and rubber/PVC that are resistant to petroleum products, oils, and other chemicals.
What Is This Pump Used For?
Its primary purpose is to safely and easily move liquids. Common applications include:
Refueling: Transferring gasoline from a jerry can to a car, lawnmower, motorcycle, boat, or generator.
Draining: Removing old gasoline, oil, or coolant from a vehicle's tank or machinery.
Transferring Liquids: Moving water, diesel, kerosene, non-potable water, or other non-corrosive chemicals between containers.
Emergency Kits: Kept in a car or garage for emergencies.
How It Works (The Operating Principle)
The pump uses a simple principle of physics: it creates a pressure difference to start a siphon.
Priming: You squeeze and release the primer bulb several times. This action pushes air out of the tube and creates suction.
Starting the Flow: The suction pulls the liquid up the dip tube. Once the liquid passes the highest point of the hose (the crest), gravity takes over.
Siphoning: The continuous column of liquid flowing downward creates a vacuum that pulls more liquid through from the source container. You can stop squeezing the bulb once the flow is steady.
Stopping: To stop the flow, simply lift the dip tube out of the liquid source or raise it above the liquid level in the source container, breaking the siphon.
Key Features & Advantages
No Power Needed: Works anywhere, anytime without electricity or batteries.
Portable: Lightweight and easy to carry in a vehicle.
Easy to Use: Simple squeeze-and-release action is intuitive.
Spill Reduction: Often results in fewer spills and drips than pouring from a heavy can, especially into small openings.
Cost-Effective: An inexpensive tool for a common problem.
