PNR’s spray nozzles for the paper industry have been engineered for specific aspects of paper production. Our nozzle range includes; flat fan coin and disc nozzles, highly accurate straight jets (also referred to as pencil jet & needle jets) and also paper web trimmer nozzles.
BRUSH-TYPE AND OSCILLATING SHOWER NOZZLES
These shower nozzles are made from 316 Stainless Steel and designed for use in Brush-Type Showers. They are available in a solid stream pattern with 316 Stainless Steel or extended-wear RUBY orifice inserts. Optional O-ring seal version is also available.
These solid stream shower nozzles are made from 316 Stainless Steel and designed for high pressure cleaning of felts, wires, fabrics and suction rolls. Available with 316 Stainless Steel or extended-wear ceramic and RUBY orifice.
The PNR GC series (coin nozzles) are our range of flat fan nozzles for the paper mill / paper production industry. GC nozzles are flush mounted and produce a very effective, sharp and accurate flat jet of water. Engineered with a round orifice they are also less susceptible to clogging. They can be fitted to a spray bar arrangement in shower pipes. These spray bars use an internal rotating steel brush for internal cleaning and easy flushing. Spray angles available are 45°, 60°, 65° and 80°. Please click here for datasheets.
PNR’s GE series disc nozzles are available as flat fan pattern and also straight jet. These nozzles are often referred to as disc nozzles. The nozzle is only 1.2mm thick and commonly used in shower pipes within the paper production industry. The shower pipes (illustrated in the diagrams above) have a steel brush inside which can be automatically or manually rotated for internal cleaning. Flat fan GE series nozzles come in 60° (GEQ) and 75° (GES). Zero degree / pencil jets or 0° (are the PNR GEA code). Please click here for datasheet.
OTHER APPLICABLE NOZZLES
PNR GDA nozzles are a classic design of needle jet (pencil jet /straight jet or 0°) nozzles that produce an accurate solid stream of water (see image with black background). They are easy to clean and and clog resistant. Used in the paper industry for high pressure cleaning and washing of felt, but also used in other industrial processes. There is a ruby insert version for operating pressures up to 200 bar ensuring a long service life and a high resistance to wearing.
These nozzles can be fitted inside shower pipes with a rotating brush for cleaning the nozzles – as illustrated in the images for the GC coin nozzles.
FAA / FBA HIGH PRESSURE straight jet nozzles: These are pencil jet / straight jet or zero degree spray nozzles that follow our flat fan range of high pressure nozzles (our F series range featured in the flat fan section of this website). Engineered in hardened 416 stainless steel for longevity and resistance to wear F series nozzles can be operated from between 20 to 200 bar pressure. Available in 1/8″ & 1/4″ threads and also known by their USG per minute codes such as 1501 / 1502 / 1503 and so forth. Please click here for datasheet.
GF series self-cleaning nozzle: This nozzle features a built in self-cleaning system. Should the outlet orifice become clogged the nozzle can be flushed through without removal of the components. The nozzle inlet orifice ( a 4.5mm diameter tube) is housed centrally in a flexible diaphragm. Under normal working pressure the diaphragm closes the inlet orifice against an anvil on the front of the nozzle and produces the desired spray pattern and flow rate. If clogging should occur the liquid pressure is momentarily reduced causing the diaphragm to return to the ‘relaxed’ position and in turn opens the exit orifice to allow any clogging particles to pass through. Once clear normal operation resumes.
GATEWOOD TRIMMING TIPS
M. L.Gatewood is pleased to introduce a line of ruby orifice edge trimming nozzles. They are available in both a single stream and double 10-degree or Parallel stream. We have completed a comprehensive development program to perfect these nozzle designs and extensive testing has been done to insure a very effective and high quality product for our customers.
The nozzles have stainless steel bodies and low friction precision ruby orifices. There is a rotating Teflon® shield that extends over the outlet end of the nozzles that keeps any moisture or debris from interrupting the stream. The shield is cut at an angle and can be independently rotated to direct the moisture runoff drips to the waste side of the cut. Orifices are available in a large range of sizes: .010″, .015″, .020″, .025″, .030″, .035″, .040″, .050″ diameters. Our double stream nozzle can be requested with two different size orifices.
Special Gatewood thread adaptors are available. For more please refer to the Gatewood website.
