Wetted Pump Materials
Polypropylene (Natural)
Polypropylene is a good general purpose plas tic material used in a wide variety of pumping applications . All-Flo does not use glas s fillers in th
polypropylene. (Glass fillers wil l attack hydrofluoric acid and s imilar chemicals ) Temperature range 32 to 150F. Natural polypropylene needs tobe protected from direct sunlight. Natural polypropylene will allow light to pas s through to the pumped material. (not suitable for UV sensitive
paints or inks).

PVDF
Polyvinylidene Fluoride or PVDF is a specialty plastic material in the fluoropolymer family and
is us ed generally in applications requiring the highes t purity, strength, resis tance to solvents,
acids, bases and low s moke generation during a fire event. Temperature range 10 to 200F. PVDF is
an FDA accepted material.

Nylon
Nylon is a m aterial used when pumping solvents, oils, paints and inks. Temperature range 10F to 150F.
Return to top of page
Conductive Nylon
Conductive Nylon is Nylon with stainless s teel fillers to allow the pump to be groundable.
Conductive nylon is used for pumping solvents that have the potential to cause an explosion
from an electrical spark from static electricity. Temperature range 0F to 150F.

Aluminum
Aluminum is a light weight metal used for many non corros ive chemicals , oils and solvents. Do not use alum inum when pumping halogenated
solvents. Temperature limit of 212F.

316 SS
316 Stainless Steel (ANSI CF-8M) is used on moderately corrosive liquids and halogenated
solvents and has excellent abrasion resistance. Temperature limit of 212F.

Electro Polished and passivated 316SS
Electro polishing or electrochemical polishing is a process that removes material from a metallic
service. Pass ivation is the formation of a hard nonreactive surface film that inhibits further corrosion
by dipping the stainless s teel in a nitric acid solution. Electro Polished and passivated 316SS pumps are normally used on food applications
where FDA approved materials are required. Temperature limit o f 212F.
