Various fuel transfer pump comes in different types and sizes. So what does a fuel transfer pump do? They require a suction hose pipe that is usually cut off at the bottom of a standard tank and enters into the pump inlet. These pumps are commonly used to fuel various machines that use engines like tankers, trucks, construction equipment, and even tractors. By using these fuel pumps you will have 10 to 30 GPM as the flow rate.
For fuel pump to work efficiently for you there are various accessories that ought to be in place. Let’s explore them with information supplied by: A company that supplies Fuel Transfer Pump – Diesel Transfer Pumps.
Accessories Needed for Fuel Transfer to Function
Some of these accessories include:
- Isolation valves – these are just ball valves that isolate the fuel pump for the service
- Flex connectors – these are basically vibration isolators that prevent any pump vibration entering into the system.
- Gauges – these basically shows the liquid levels and the pressure for the outgoing fluid
- Check valves – these are specially located at the outlet to prevent backflow of the liquid through the pump and also at the inlet to maintain and retain the prime on the pump
- Strainers – these prevent and keeps off any debris into the system which consequently may damage the pump
- Pressure relief/regulating valves – when the lower valves are closed these pressure relief valves allow flow in the pump and also prevents overheating during pumping.
In the case of determining the flow rate for boilers and generators, you need to take the consumption of all the boilers/generators when they are fully loaded and multiply them by two. This will ensure your pump works efficiently without starving the flow in the last boiler/generator.
Types of Fuel Transfer Pumps
There are 3 primary types of fuel transfer pumps:
Positive displacement or Gear pump
This pump is used to transfer fuel from large tanks to generator or from a generator tank return. It is fitted with a filtration system that prevents any debris. In addition, it has boiler feed pumps that give it a feature of excellent suction with very high-pressure output capability. It is available in various voltages and horsepower.
Despite having excellent pumping, it has more noise and vibration than others and due to the high flow rate, it becomes costly. One of the most common problems with this pump is a loss of prime in the suction piping.
This pump is best used in transferring liquid to and from various delivery tankers to storage tanks. They cost less compared to their high flow rate however it has a limited suction that is; capacity will decrease at high pressures. In addition, it has some difficulty in its prime.
Submersible turbine pumps
It is mostly used to transfer fluids from the tanks that are under and above the ground to generators, tankers, and boilers that require limited pressure. It does not have any issues with suction and prime giving high flow rate with low costs. However, it may not be used in shallow tanks and low flow applications.
Maintenance and Inspection Required in Fuel Transfer Pump
A fuel transfer pump requires weekly inspection of any leakages which need to be catered for as soon as possible to avoid any damage. There should be an annual check of terminal tightness.
Any part that is movable should be lubricated to reduce friction. Check the operation of the pumps continuous for efficiency.
In conclusion, if you have not thought of acquiring a fuel transfer pump yet you are dealing with transferring and transporting various fluids, rush and acquire yours for easier functioning.
