Usage tips

Whether refueling in a vehicle, transferring oil into a tank, oil from a barrel or emptying a tank, you cannot use a submerged pump. The solution: a transfer pump! Depending on the needs, manual or electrical, the important thing is to choose it!

What is a transfer pump?

As the name implies, a best transfer pump is a water pump used primarily to pass a liquid from one tank to another . Simply for water, or on the contrary for specific fluids (fuels, oils, chemicals, etc.), a transfer pump is designed not to put the user in contact with liquids. The fact that the pump itself is not submerged protects its mechanism, and avoids premature wear, leaks and odors. In addition, maintenance operations on this type of pump are limited.

What are the different types of transfer pumps?

We can find two major families of transfer pumps whatever the fluid for which they are intended! The manual transfer pumps are for small amounts of liquid. They are reliable and simple in design. There are two main types, follow the guide!

 Ball transfer pump or siphon pump

Using the principle of communicating vessels, this is the most basic type of transfer pump. Consisting of a simple pipe on which is mounted a cap trapping a ball, this pump is mainly used to transfer punctually small amounts of fuel (motor crops, boating etc.) or water. The hose is between 1 and 2 m long, for a diameter ranging from 10 to 25 mm. The average flow rate of this type of pump is 30 l / m (liters per minute).

Easy to boot and requiring no maintenance other than cleaning after use, it is a safe bet at a lower cost. The only drawback is that the receiving tank must be lower than the source tank.

 Cane transfer pump

Specific to vats, casks and barrels, crank or lever, they are often found in workshops. They are of various shapes and sizes – especially as regards the diameter and length of the cane. The drum and barrel-specific models feature 2 “(2”) threads that comply with the standard plugs, making the pump integral.

The pump casing is in most cases made of cast iron. It is ideal for low viscosity oils, oil or diesel. For gasoline, however, it will be necessary to verify that the model is suitable. If you have large volumes to transfer, direct your choice to a crank pump – the average flow is about45 l / m  ; if on the contrary you have to pump small quantities , a lever is perfectly suitable – about 0.3 to 0.5 l per lever stroke. Relatively simple design, this type of pump requires little maintenance – cleaning, periodic change of joints.

Electric transfer pump

Designed for large volumes or frequent uses. Mainly used in fuel stations, these pumps are also capable (provided you choose a suitable model) of transferring chemicals (specific treatment of the pump body), gasoline, and liquids (milk, wine, etc.). They can be part of a fixed installation operating at 230 V (volts) or a mobile system in 12 V or 24 V. For large volumes, pay attention to the power of the motor and the diameter of the suction pipes and of discharge because the flow depends on it.

The vast majority of electric transfer pumps are said to be self-priming, which means that the pump body and the suction pipe do not need to be full of liquid (or air voids) for pumping. Started.

If you buy a model that is not, then it will be imperative to mount a check valve on your backflow otherwise you will have to redo the filling manipulation of the suction and the pump body with each use. Depending on your needs, choose the right type of pump especially if you have to transfer solvents, alcohol or gasoline – risk of explosion.(wheel, pallets) will depend on the specificity of the model. It is strongly recommended to mount a strainer on the suction to prevent clogging or blockage of the pump. Maintenance is limited to gaskets and the electric motor – bearings, fan, and terminal board.

 Usage tips

Regardless of the type of liquid you want to transfer, always check before you decide that the pump model you have selected is suitable.

The risks are many with hydrocarbons and chemicals in particular, do not neglect!

For stationary use, check regularly that the floor is clean and dry.

Be on the lookout for the slightest leak and seal it up quickly!

Other pumping requirements are met by immersed pumps or surface pumps.
