Kerosene fuel has different properties compared to gasoil :

• much lower viscosity, meaning that the internal leakages between the moving parts of the pump are increased giving a reduction in available nozzle flow capacity.
• lower lubricity of the pump inner parts.

Due to these properties, kerosene use requires precautions in the selection and use of burner pumps.
There are many qualities of kerosene in the different world markets which give varying effects on pump life (kerosene is a low lubricity fuel).
Suntec has got years of experience with kerosene and has developped a wide range of pumps for these applications.
All these pumps can be used at 2850 or 3600 rpm.
Do not exceed the maximum recommended pressure,
Ask us for pump capacity curves (for viscosity : 1,25 cSt).

To fulfill the market requirements Suntec has developped a special range of models issuing from standard
AN, AE, AS, AL, AP2, AT2 types with high precision gears.
These models are available with gear capacity sizes : 35,45,47,55,57.
These models are identified with their own reference number,
ie : pump reference AS 47 CK 1554 6P 0500 is a special kerosene model.
The maximum recommended pressure for these models is :
15 bars.

E Revision 6

When introducing the new Rota Roll gear in 2000, Suntec has taken into account the kerosene properties so that the standard version of E pumps is now suitable for both light oil and kerosene applications.
So for kerosene applications we recommend the use of E4 and E6 new Revision 6 pumps with maximum pressure : 15 bars; these models are much more adapted than J models.

TA and T pumps

Since early 1999 TA and T pumps have been improved to be suitable for kerosene use till 20 bars, in standard version.
