Polypropylene (PP) Spiral Spray Nozzles
Spiral nozzles with a large, open flow path that keeps spraying even when the liquid carries solids. Moulded in chemical-resistant polypropylene for scrubbers, cooling and process washing.
- Large free passage resists clogging
- Full cone and hollow cone patterns
- All common thread sizes, made to order
PolypropyleneOverview
Why choose a spiral nozzle?
A spiral nozzle has no internal vanes. The liquid hits a series of spiral turns that cut it into concentric sheets of spray, so the flow path stays wide open from inlet to tip. That makes spiral nozzles a dependable choice for recirculated water, slurries and dirty process liquids that would block a vaned nozzle.
Polypropylene adds the chemical resistance that scrubbers and treatment plants need. It handles most acids, alkalis and salt solutions at moderate temperatures and costs far less than PVDF or stainless steel.
Typical applications
- Fume and gas scrubbers
- Cooling towers and gas cooling
- Effluent and wastewater treatment
- Dust suppression
- Tank and vessel washing
- Fire protection deluge (non-certified)
Benefits
Why choose our pp spiral spray nozzles
Clog-resistant
No internal vanes, so suspended solids pass straight through.
Chemical resistant
PP stands up to most acids, alkalis and salt solutions.
Fine, even droplets
Spiral turns break liquid into a dense, uniform spray.
Low maintenance
One-piece design with nothing to wear out or jam.
Cost-effective
Plastic moulding keeps the price low for large orders.
Made to order
Choose thread size, spray angle and flow to suit your line.

FAQs
PP Spiral Spray Nozzles: frequently asked questions
What is a spiral spray nozzle used for?
Spiral nozzles are used where a wide, dense spray is needed from a nozzle that will not block easily: gas scrubbers, cooling towers, gas cooling, effluent treatment and dust suppression.
Why do spiral nozzles not clog?
There are no internal vanes or small passages. The liquid exits through a large open orifice and is cut into sheets by the spiral turns, so particles pass straight through.
Can PP spiral nozzles handle acids?
Polypropylene resists most dilute and many concentrated acids, alkalis and salts. For strong oxidisers, solvents or hot liquids we recommend PVDF. Tell us the chemical and temperature and we will confirm the right material.
Full cone or hollow cone: which do I need?
Full cone covers the whole circular area and suits scrubbing and washing. Hollow cone gives a ring of finer droplets and suits gas cooling and absorption. If you are unsure, share your application and we will advise.
What information do you need for a quote?
The thread size, operating pressure, flow per nozzle (or total flow and number of nozzles), the liquid and its temperature, and the quantity you need.
Do you supply small quantities?
Yes. We supply single replacement nozzles as well as bulk orders for new plants.
