A transfer pump uses to pump different fluids from one location to other. The fuel
transfer pump transports fuel from a container to a nozzle or from one tank to
another so that it is delivered to the automobile. Pumps can also use to move fuel
from one vehicle to another or to remove fuel from an automobile and return it to a
storage container. The diesel transfer pump plant uses to power all types of diesel
automobiles, including equipment, trucks, cars, coaches, trucks and buses. The
diesel transfer pump introduces fuel into the fuel system, allowing it to move from
one location to another. These pumps are also used in various industries and

In large or frequently used gas stations, most fuel supply pumps are battery
operated, but hand pumps can also be used, which are suitable solutions for certain
Manual fuel transfer pumps have two main advantages over power pumps. The
cost of these manual transfer pumps is low. They can efficiently distribute or
transfer small amounts of fuel from one container to another or supply fuel from a
drum. Manual pumps do not require a power source. They can be used anywhere
without having to worry about whether the power source or the battery is fully
Fuel transfer pumps must use a suction hose that is cut at the bottom of the fuel
tank and scraped inside the pump chamber under the pump. Maximum types of
transfer pumps have a 1 "or 3/4" release hose. These are ideal for transferring fuel
from one place to another.
Types of Fuel Transfer Pump
Transfer pumps have the following main types:
1) Gear pump
It is also known as a positive displacement pump. Gear pumps use gear grids to
pump fluid through displacement. This is one of the best-known types of pumps
used in hydraulic applications. These pumps can carry fuel from the fuel tank to
the generator, boiler feed water pump, generator tank return flow pump and filter
polishing system. Common brands are Thuthil, Blackmar and Viking. The gear
pump has exceptional suction characteristics up to 20 vertical feet. They have high
pressure generating capacities of up to hundreds of PSI and very low to high flow
rates ranging from 0.25 to hundreds of GPM.
Suction channel characteristics make initial and primary problems difficult to
manage. Gear pumps with a higher flow rate tend to cost more. They may have
more vibration and noise than other methods. Loss of priming in the suction line is
a very common problem.
2) Submersible Turbine pump
These pumps can use to transport fuel or oil from above-ground or underground
storage tanks at a limited pressure to the generator's daily storage tank and boiler
feed water. FE Petro and Red Jacket are well-known brands of submersible pumps.
No priming or suction problem with these pumps. This fuel transfer pump is
relatively inexpensive and has a relatively high flow rate.
It has some limitations:
Pressure limit 50 psi.
It is 120 VAC and not suitable for low flow purposes.
Not suitable for generator-based water tanks like shallow water tanks.
A headroom is required above the storage tank prior to installation in the
The most famous problem is high flow.
3) Centrifugal Pump
The centrifugal pump directs the flow of fuel into the bulk material container
between the automobiles in the suction state. Gorman Rupp and Gold are the
common brands of these pumps. These pumps offer high flow rates at low cost.
These have some limitations:
Limited suction power.
High pressure reduces efficiency and the most common problem is trouble
4) Diaphragm / blower pumps
The diaphragm pump can use when pump process fluid contamination or leakage
is not acceptable. These transfer pump Peristaltic pumps provide freedom from
external leakage, but allow for higher pressure and easier flow adjustment.
How to choose a fuel transfer pump?
There are many types of fuel transfer pumps on the market. Most of them are
simple and have different functions for different applications. There are a lot of
factors to consider when choosing a transfer pump. These factors are listed below:
1) Complete fuel distributor or pump
First, you need to decide if you need a diesel supply pump, replacement or
complete fuel supply unit with hoses, nozzles and flow meters. Customers who
purchase the main unit or replace the entire system will benefit best from a
complete power supply unit. On the other hand, if only the pump needs to be
replaced, the customer who is already using a refueling system will choose the
2) Required flow rate
Variation in flow rate is the rate at which fuel is distributed. Fuel is delivered
quickly when the fuel flow rate is high. Mostly, it measures in liters per minute.
3) Coverage area of the pump
If you want to pump fuel over a large area you need a larger pump. Always
remember that large pumps are not always the best.
4) Power supply
The 400V, 110V and 230V AC network can be used for both fuel supply
equipment and individual pumps. When choosing the right pump, make sure the
pump has the required power.
To choose the right transfer pump, you need to know the viscosity of the fuel you
are sending. Higher viscous fuels require more hygienic pumping equipment.
Therefore, fuel viscosity is an important factor for pump selection.
How hot is the pumped fluid? This will affect the best pump material for your
The inlet and outlet pressure of the pump should be considered during the selection
of the pump. You can use this information to identify the right device.
The price of the pump is another important factor you need to remember.
