Hoffer Helps Pharmaceutical Giant “WFI” Headache
Ultrapure deionized water is commonly used in the healthcare industry to manufacture eye drops, nose spray, and hygiene products. This highly purified water sometimes referred to as “WFI” (Water for Injection) or compendial water, presents many challenges for a flowmeter.
WFI is non-conductive, corrosive to certain metals in nature, and requires a sanitary-style flowmeter. The Hoffer Sanitary Series flow metering products meet the requirements and are used routinely throughout the industry with excellent results. The BPE-compliant sanitary design, 316 stainless steel construction, and wide turn-down make the Sanitary Series an excellent solution for a WFI application.
“CIPable” or suitable for “Clean in Place
Pharmaceutical industry standards require that all flow measurement and other process devices be fully “CIPable” or suitable for “Clean in Place.” This means that the flowmeter must be fully cleaned when flushed with a suitable cleaning product or steam.
The Hoffer Sanitary Series of turbine flowmeters incorporates a design that is fully cleaned when flushed. Furthermore, this series of flowmeters are available with a hard carbon composite sleeve bearing suitable for steam cleaning.
One Hoffer customer, an international manufacturer of healthcare products who employs 54,000 people looking for a solution to a problem, came to Hoffer to discuss a WFI application. The flowmeters then used in their WFI process were routinely being replaced.
The cast internal assembly with a Rulon sleeve bearing was deteriorating after a few (CIP) cycles. The downtime, 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 Sanitary Series turbine flowmeter was the most accurate and cost-effective solution for the application.
Sanitary Series provides Flow Measurement
The Sanitary Series provides flow measurement capability from .35 to 650 GPM in flowmeter sizes ranging from 1/4″ through 3″. The Sanitary turbine flowmeter provides a turndown range of 10:1 to 40:1 depending on flowmeter size. A clamp-type sanitary process connection is standard.
The meter is fully “CIP-able.” Construction consists of 316/316L dual rated stainless steel body and hangers, 17-4 ph stainless steel rotor, and a carbon composite sleeve bearing.

Purified Water Flowmeter from Hoffer Flow Controls
Hoffer Turbine Flowmeters are available in a broad range of standard and special materials. The wide range of construction options allows for selecting the optimum combination of useful range, corrosion resistance, and operating life for a particular application. A low mass rotor design allows for a rapid dynamic response which permits the turbine flowmeter to be used in pulsating flow applications.
