Component Recognized 
(E85349)
Side and Top Mount
Corrosion Resistant Plastic with Optional Metal Pivot Pin
LOW COST RELIABLE DESIGN
- G.E. Noryl® Polyphenylene Oxide (PPO)
is suitable for acid and base solutions, pure water, process water, sea water, filtered
sewage, contaminated groundwater... Noryl® is not suitable
for use in hydrocarbons, petroleum, alcohol and related chemicals.
- The wetted surface of Model L-40 is entirely of Noryl®
(PPO) or Fortron® (PPS) except for a small float support
Pivot Pin.
- Float support pivot pin is supplied in a variety of
materials i.e. 316 Stainless Steel, Hast.® C, Titanium,
Tantalum and Teflon® to meet special chemical and operations
environments.
- Hoechst Celanese Fortron® Polyphenylene
Sulfide (PPS) is suitable for strong acid and base solutions. All of the
solutions listed above including hydrocarbons, petroleum products, alcohols, etc. Fortron®
(PPS) is a member of a select class of chemically resistant plastic resins for use in a
very broad spectrum of chemicals.
10 times less sensitive from
deposit and build-up of contaminants than sliding float models.
