ALLFUEL® Series
Unleash Efficiency with the 2nd Gen Oil Transfer Pumps
The 2nd generation of the Allweiler ALLFUEL® series was designed specifically for the efficient transfer of fuel oil, lubricating oil, and hydraulic oil. The ALLFUEL® three-screw pumps are recognized worldwide for their reliability as transfer, booster, and burner pumps in oil firing technology, fuel systems for marine vessels, as well as transfer and filling pumps in tank farms and lube oil pumps throughout all industrial sectors, operating at pressures up to 40 bar.
Their versatility and performance make three-screw pumps the optimal choice for demanding applications, such as pumping low-sulfur marine fuels or marine diesel (MGO). The ALLFUEL® series offers various designs, including models with either mechanical seal or magnetic drive for maximum safety. Regardless of the version you select, you can count on constant and secure pumping of your media.
Key Advantages
Fast Maintenance
Only one third of the time thanks to easy (dis)assembly of the pump insert
Long Service Life
External bearing, wear-protected SiC/SiC mechanical seal or magnetic coupling, patented new hydraulic system with inverted comb bearing and integrated thrust compensation
High Efficiency
Even with demanding, low-viscosity fuels such as low-sulfur MGO
Continuity
Fits into most housings of the old SPF or ALLFUEL series
ALLFUEL® Three-Screw Pumps
Next-Gen Innovation for Maximum Uptime
The 2nd generation ALLFUEL® three-screw pumps boasts an innovative, user-friendly design that minimizes downtime. Our one-piece insert unit simplifies maintenance and cuts down repair time by one-third. Besides being easy to install, the insert unit is incredibly durable due to its external bearing, which never touches the pumped medium.
Our wear-protected SiC/SiC mechanical seal or magnetic coupling ensures a longest-lasting sealing. The new patented hydraulic system with an inverted comb bearing and integrated thrust compensation is highly durable.
Effortless Switching and Easy Cleaning
The Ultimate Filter Innovation
The 2nd generation ALLFUEL® three-screw pumps
A central ball valve with a straightforward direction setting makes switching easy. Our innovative design ensures efficient flow through the filter from the inside out, keeping dirt and metal chips securely inside and preventing them from entering the pump housing.
A notable feature of our filter is its easy cleaning. It can be easily extracted without requiring the medium to be drained. This pragmatic approach saves time and ensures seamless operations for your processes.
