With the exception of special usage for fuel oil EL, the nozzles can be used for all oils the viscosity of which does not exceed 5 cst (1.4° E).
The Type HO models (see below) can also be used for oils with a viscosity
up to 13 cst (2.1 °E).
Selection
The series comprises 72 discharges from 1.5 l/h to 378.5 l/h (0.40 to 100 US GPH).
The use of fuel oil EL at normal operating temperature may vary the discharge by approx. 1%.
The discharge increases with viscosity.
Operating pressure
The nozzles are tested at an operating pressure of 7 bar with fuel oil EL
(see discharge tables on the next page).
The recommended operating pressure for nozzles (for fuel oil EL) is between 6 and 25 bar (please ask for using at higher pressure).
For fluids with a higher viscosity, they can work with an operating pressure of 10 – 14 bar. However, the spray angle decreases drastically (heavily), except if nozzles are used that are specially designed for such applications (see HO nozzle).
Nozzle with porous bronze filters
These filters, where all nozzles are equipped from 0.40 – 1.00 GPH, achieve very good filtering (filter fineness 25 – 50 microns).
This filter has huge advantages to protect the nozzles with small discharges (under 1.00 GPH). The accumulation of small bronze balls forms a series of obstacles, which results in considerably better filtering than for simple screen filters. Therefore, the sensitive internal parts of the small nozzles are better protected. This filter withstands high temperatures.
Nozzle with mesh strainers
Nozzles from 1.10 GPH to 9.5 GPH (4.16 – 39.7 l/h) discharge are all equipped with mesh strainers (Monel), mesh width 120. For larger discharges up to 30 GPH (113.5 l/h), this type of filter can also be used, but is then separately supplied as an extra.
