SK Series SprayDry nozzles produce a hollow cone spray pattern with a very uniform drop size distribution. They also offer a choice of drop sizes that are controlled by the nozzle's capacity and pressure. SK nozzles are suitable for use in all types of spray dryers, flow systems, and open- and closed-cycle installations.

A choice of three models, each with different design features

SKH-MFP (Maximum Free Passage) SprayDry nozzles offer hand-tight design and clog-resistant features:

  • Use of an O-ring instead of a gasket allows the cap to be tightened by hand and securely seals at high pressures to 7000 psi (450 bar). No tools are required which simplifies maintenance in hard-to-reach places
  • Core and cap design offers increased free passage without changing spray performance. Clogging is reduced and production uptime dramatically increased
  • MFP cores have at least two slots. This provides for a superior spray pattern, improved particle size distribution and a more uniform bulk density when compared to single-slot designs. The MFP design also minimizes pressure drop
  • Anti-bearding design reduces build-up in the nozzle orifice minimizing contamination concerns and maintenance time
The SK-MFP is a maximum free passage version without hand-tight and anti-bearding features.

The SK nozzle is a reliable, basic spray dry nozzle without the maximum free passage or hand-tight features.

SK SprayDry nozzle overview:

  • Choose from 145 interchangeable orifice insert/core combinations
  • Capacity sizes from 3.9 to 151 gph at 1000 psi (14.9 to 576 l/hr at 70 bar) (based on spraying water)
  • Spray angles from 45° to 90°
  • Larger capacity orifice insert/core combinations can be used at lower pressures to minimize nozzle and pump wear
  • Maximum pressure is 7000 psi (450 bar)
