There is often a question as to whether someone would need an Oil Lifter or Pressurised Pump Unit, and the answer is highly dependant on the situation they are in. The ultimate value of understanding which option is best for you, is shown through the effectiveness, efficiency and success of the process and outcome.
Oil Lifters – Notably OUF 88

Oil lifters transfer oil to high-level installations by sucking fuel from the storage tank into an internal reservoir. This stored oil then feeds the boiler.
An oil lifter works well when a de-aerator cannot handle the burner’s height or distance. De-aerators typically have a 4m suction height limit. Oil lifters, with built-in pumps, outperform them by providing up to 8m suction height.
They also help when the boiler sits above the oil level in the storage tank. Since liquid needs force to move uphill, an oil lifter creates a vacuum to pull fuel up and gravity-feeds it to the appliance.
Oil lifters offer a major advantage in areas with frequent power failures. Their internal reservoir keeps vaporizing burners running, ensuring heating continues without electricity.
Pressurised Pump Units – Notably AN20

Pressurised pump units efficiently supply oil to single or multiple appliances. An internal pressure switch activates them only when fuel is needed.
They outperform oil lifters when pumping oil over long distances. Capable of reaching 1500m horizontally or vertically, they ensure reliable fuel delivery. Unlike suction-based systems, pressurised pumps use force to push oil, allowing greater range and efficiency.
Installation is quick and simple for both domestic and commercial sites. With just two connections—one to the storage tank and one to the appliance—setup is hassle-free. Most units are also self-priming on first use.
Pressurised pump units excel when supplying more than two pressure jet burners. They maintain high efficiency while handling multiple appliances simultaneously.
Direct Comparison
Oil Lifter
How They Work – Sucks oil up from the storage tank.
Location – Must be located and installed above the burner or appliance.
Features – Max flow rate of 15l/hr, the unit monitors the level of oil then supplies more oil when the levels are below a set point.
Jet Burner Usage – Performs best with one pressure jet appliance at a time
Pressurised Pump
How They Work – Pumps fuel under pressure directly to the appliance from the tank
Location – Can be installed in multiple positions
Features – Max flow rate of 20l/hr, operated by a pressure switch ensuring the appliance always has fuel
Jet Burner Usage – Perfectly suited to working with multiple jet burners / appliances
In conclusion
In conclusion, the choice between an Oil Lifter and a Pressurised Pump Unit ultimately depends on the specific requirements of your installation.
Oil Lifters like the OUF 88 are ideal for high-level installations where suction height is a concern, locations prone to power failures, or setups requiring a gravity-fed solution.
On the other hand, Pressurised Pump Units such as the AN20 excel in long-distance oil transportation, multi-appliance setups, and easy installation with self-priming capabilities.
By understanding the strengths of each option, you can ensure an efficient, reliable, and cost-effective fuel supply tailored to your needs. If you’re unsure which solution is right for you, get in touch—we’re happy to help!
