"WFI" Headache
Ultrapure deionized water: Recently a Hoffer customer is
commonly used in the health care industry to manufacture
products such as eye drops, nose spray, and hygiene products.
This highly purified water, sometimes referred to as "WFI"(Water
for Injection), presents many challenges for a flowmeter.
WFI is nonconductive, corrosive in nature and requires a
sanitary style flowmeter. The Hoffer 3A Series meets the
requirements and is used routinely throughout the industry
with excellent results. The sanitary design, 316 stainless
steel construction and wide turndown make the 3A Series
an excellent solution for a WFI application.
Health care industry regulations require that all flow
measurement and other process devices must be fully "Capable",
or suitable for "Clean in Place". This means that the flowmeter
must be fully cleaned when it is flushed with a suitable
cleaning product or steam. The Hoffer 3A series of turbine
flowmeters incorporates a design that is fully cleaned when
flushed. Furthermore, this series of flowmeters is available
with a hard carbon composite sleeve bearing that is suitable
for steam cleaning. Other turbine flowmeter manufacturers
offer sanitary turbine flowmeters with Rulon (a PTFE compound)
sleeve bearings. Rulon's maximum operating temperature is
typically +250° F, which is not suitable for steam cleaning
above 15 psig. The Hoffer 3A meter supplied with a hard
carbon composite sleeve< bearing offers a temperature rating
suitable to +850° F.
Recently a Hoffer customer
an international manufacturer of health care products
who employs 54,000 people, looking for a solution to a problem
came to Hoffer to discuss a WFI application. The
flowmeters currently
used in their WFI process were routinely being replaced.
The cast internal assembly with a Rulon sleeve bearing was
deteriorating after a few (CIP) steam-cleaning cycles. The
down time, replacement cost, and potential contamination
from a deteriorated set of internals required immediate
attention and a quick resolution from their maintenance
personnel. The customer determined that the Hoffer 3A Series
turbine flowmeter was the most accurate and cost effective
solution for the application.
The 3A Series provides flow measurement capability from
.25 to 800 GPM in flowmeter sizes ranging form 1/4" through
3". The 3A turbine flowmeter provides turndown range of
10:1 to 40:1 depending on flowmeter size. A clamp type sanitary
process connection is standard and the meter is fully "CIPable".
Construction consists of 316 stainless steel body and hangers
(316L stainless optional), 17-4 ph stainless steel rotor,
and a carbon composite sleeve bearing.
Hoffer is please to provide 3A sanitary flowmeters for
the health care industry. Perhaps a process in your plant
includes deionized, demineralized, or "WFI" water? Or it
must meet 3A Sanitary requirements? Let us help. We have
been providing turbine flowmeters throughout the world for
almost 30 years.
