AdBlue™ Pumping Equipment Specifications
AdBlue is very susceptible to contamination from both foreign matter and incorrect material selection. It is imperative that this is considered when deciding which dispensing solution is best for your application. Particulate ingress is an obvious problem for any transfer application but less evident problems are often overlooked.
One problem which continues to haunt pumps that are not specifically designed for handling AdBlue is that crystals can form and damage internal components. Due to the high crystalline content of the urea solution a chalky abrasive residue builds up when the DI water content evaporates or dries. This can occur anywhere where air can enter or get trapped in the system.
These crystals can cause uneven wear on motor shafts if left to build up on inner pump walls or pump impellors and may drag around the circumference of any seals causing further damage and deterioration of both components. Parts of broken impellor and seals can then pass through to the tank on the vehicle and melt onto the superheated head of the SCR.
The most common causes of premature SCR failure are typically either a result of the ingress of damaged pump parts or as a result of incorrect material selection. The main influence in this instance is where the de-ionised water element of the solution draws ions from materials it comes into contact with, this changes the chemical composition of the AdBlue and causes salts to form which in turn clog the Ceramic head on the SCR. Inert materials should always be used to handle AdBlue.
Materials which are most likely to cause these problems are Zinc, Aluminium, Copper, Cast Iron and Brass. Plated and treated materials should also be avoided as the plating can wear away on contact/moving parts. Nickel plated aluminium regardless of being treated as either a electro-less or electrolytic process should be avoided at all times, this is regretfully a common error with existing systems. More Information on this is covered in our section on delivery nozzles for AdBlue.
Below is a selection of the available pumps for AdBlue transfer, you should never use diesel transfer pumps or fuel storage tanks for handling AdBlue
Horn GmbH
W60 H
The 4th Generation of the most widely used AdBlue pump in Europe, the first pump built specifically for use with automotive urea solution. Goes from strength to strength, built to a very high standard with a unique patented induction/hybrid impellor design. Switches from positive displacement pump to centrifugal as the pump chamber fills with fluid. This unique design ensures that the pump remains self priming, self cleaning and reliable. Easy to switch between IBC’s/tanks when used with a CDS coupling.

Self Priming to 2.4m
35 litre/min
1.6 Bar
230v AC (500w)
IP24
All product-contact parts comply with the CEFIC quality guidelines |
Advantages: Cleans itself from residual build up, eliminating the need for regular maintenance, works in any orientation, life expectancy of 300000L of AdBlue (equivalent to 6000000 litres of diesel consumption)
Disadvantages: Only IP24 rated, so not suitable for outdoor use unless sheltered from rain. One of the more expensive AdBlue pump solutions but quality comes at a price.

PIUSI S.p.a
Suzzura Blue
A very powerful pump delivering a massive 5 bar delivery pressure, probably the second biggest selling unit in Europe mostly due to it’s economical price which has been embraced by many distributors of AdBlue solution. The robust IP55 rated motor makes the device suitable outdoor use.
2m suction lift makes it suitable for medium sized tank installation.
 |
Not self priming, lift 2m when manually primed (dry priming to 0m)
40 litre/min
5.0 Bar
230v AC (370w)
IP55
Made from compatible but not approved materials |
Advantages: Large delivery pressure makes this one of the best solutions for long delivery runs, one of the few pumps providing IP55 protection. Competitively priced.
Disadvantages: Only self priming after initial fill which involves breaking the discharge line and back filling pump chamber with liquid, this massively increases risk of contamination unless conducted under strict controlled conditions. Not a quenched rotary seal and therefore requires regular maintenance.

ZUWA GmbH
NIROSTAR 2000 A/B
Available in two flowrates (A = 30 litre/min and B = 60 litre/min) and capable of a maximum 8m self priming lift if installed correctly, this pump provides an ideal solution to most larger tank applications.
Made from Stainless steel, various impellors/seal materials and available in 4 different voltages this pump offers the most number of diverse configurations.
 |
Self priming to 8m (dry priming to 3m)
30 or 60 litre/min
4.0 Bar
230v AC (200w)
IP54/55
Made from compatible but not approved materials |
Advantages: Available in 230v, 400v, 12v and 24v, best solution for large storage applications
Disadvantages: Does not offer a self quenching seal, requires routine maintenance to prevent risk of deterioration of internal components.

GESPA.S.A
ADB40
Very similar to the Piusi Suzzura Blue but less powerful, still suitable for medium sized tank and IBC dispensing. Another good contender from this manufacturer who is relatively new to the Urea market.
 |
Not self priming, lift 2m when manually primed (dry priming to 0m)
40 litre/min
3.2 Bar
230v AC (370w)
IP44
Made from compatible but not approved materials |
Advantages: Competitively priced
Disadvantages: Not self priming.
AGB40
Built from Polypropylene and stainless steel from a design based on a common positive displacement diesel pump using a rotary vane mechanism.
Only recently produced this pump is yet to stand the test of time, although if indeed suitable for long term use this pump has all the right ingredients and a price which could easily make it a market leader.
 |
Self Priming to 5.0m (dry prime 2.5m)
40 litre/min
3.0 Bar
230v AC (250w)
IP55
Made from compatible but not approved materials |
Advantages: Self priming, competitively priced
Disadvantages: Plastic body can be cross threaded if care is not taken when sealing

Lutz GmbH
B2
As with many German built AdBlue handling components this pump is custom made for this dispensing application. The 1.4 bar delivery pressure ensures it is suitable for medium to long dispensing hose runs. Easy to fit for drums and IBC’s although does not accommodate the CDS coupling which risks the static suction pipe being mishandled leading to an increased risk of product contamination.
Made from polypropylene, supplied with EPDM/Viton seals, Stainless steel drive components
 |
Self Priming
0-60 litre/min
1.4 Bar
230v AC (200w)
IP24
Made from approved materials |
Advantages: Benefits from a speed controller allowing the 60lpm max flow to be easily controlled for smaller fills. Also is fitted with dry running protection. Self priming.
Disadvantages: only IP24 rated, so not suitable for outdoor use unless sheltered from rain. Not really suitable for dispensing from tank storages larger than IBC’s

Flux-Geräte GmbH
F424 PP/S
A typical IBC pump, not specifically made for AdBlue but every bit compatible. Constructed from suitable materials and able to handle the AdBlue solution. With the only disadvantage being the static uplift pipe requiring transfer during IBC changeover which risks contamination if incorrectly handled. Made from PP, PVDF and St316
 |
Submerged induction (self priming)
10-37 litre/min
1.1 Bar
220v AC (450w)
IP24
Made from approved materials
|
Advantages: Available with brushless ATEX EEx motor suitable for Zone 0 use, suitable for up to 1.5m suction lifts
Disadvantages: Static induction pipe risks contamination if handled incorrectly between IBC/drum changes.
Juniorflux
20lpm equivalent of the F424 PP/S designed specifically for drum dispensing.
