FIBREWOUND PRESSURE TANKS

SR48

Built Tough… for Quality
Every Signature 2000® tank
utilizes a durable, FDA approved
air cell which is resistant to chlorine and will not promote taste
or odor problems associated
with iron bacteria that may be
present in the water supply.

Built Tough… for Durability

SR60

Each tank is wrapped with more
than three miles of over-lapping,
continuous fiberglass strands,
sealed with high grade epoxy
resin, then oven cured. Tough
composite construction means
longer lasting tanks that will not
rust, corrode, dent or scratch.

SR35
SR20

Built Tough… for Easy
Installation and Service
Not only is composite construction tougher, it's also more lightweight… as little as half the
weight of steel tanks. Installation
is faster, easier and can be
handled by one person. Repairable with the tank installed.P

FEATURES

Use wherever pressurized
tanks are needed in water
systems applications.

SPECIFICATIONS
Inner Liner – One-piece highdensity polyethylene
Outer Shell – Fiberglass-wound and
epoxy resin sealed
Air Cell – Heavy mil ethyl-vinylacetate (EVA)
Upper and Lower Flanges –
Reinforced polypropylene
Base – One piece high density
polyethylene
Service Connection – Stainless
steel on all models
Air Valve – Brass body, Schrader
core assembly
Weather Cap – High density
polyethylene

Signature 2000® Fibrewound
Pressure Tank assembly is
classified to ANSI/NSF Standard
61 for water system components.
Tank Base – Rigid molded polyethylene is the sturdiest composite
base on the market. Corrosion- and
impact-resistant. Base rotates 360°
for ease-of-service hook-up.
Replaceable Air Cell – With the
tank installed! Air cell access is via a
top mount design. Generous and
accessible air cell opening facilitates
easy removable and re-installation of
replacement air cell (with the professional contractor in mind).
Five Year Warranty – Managed and
provided by WICOR Industries, the
only US manufacturer to design and
manufacture fibrewound and steel
tanks!
■

Durable Composite Construction –
A rugged one-piece molded, inner-liner
of premium high-density polyethylene.
■ Miles of continuous overlapping
fiberglass strands, sealed with
oven cured epoxy make the
outer-shell impervious to rust,
dents, and ultra-violet rays (no
paint to scratch and touch-up).
■ Proprietary wrap pattern makes
the tank stronger than steel.
Tanks can be installed with a
wider range of pressure settings,
so you can select the system
pressure you want.
Air Cell – The air cell is fabricated
from durable and extensively tested
ethyl-vinyl-acetate (EVA).
■ EVA is resistant to chlorine.
■ EVA will not support iron bacteria
growth that may be present in
the water supply.
■ EVA and Polyethylene meet FDA
requirements for potable water
supplies.

TANK SIZING RULE:

®

Size tank for one gallon of drawdown for each gallon per minute at
pump capacity.
EXAMPLE: For a 1 HP - 20 GPM unit pumping 20 gallons per minute on a
30-50 pressure switch setting, the properly sized Signature 2000® tank is
a SR85-25, which has a 25.1 gallon drawdown.
