JVNW began manufacturing pharmaceutical tanks in the early 80's. A few projects at a time for local companies, keeping our focus on quality rather than quantity. It wasn't until JVNW moved into its state-of-the-art production facility in 1997 that we were able to produce tanks in sufficient quantities to service the complete pharmaceutical industry.
Portable Transfer Vessels
We are an ASME coded facility, fabricating vessels and our own line of sanitary mixers that includes the patented ultra-sanitary Sanifoil impeller. The Sanifoil is our most sought after impeller, its proven performance is completely "CIP-able", eliminating all shadows.
JVNW is equipped for riboflavin testing, a procedure that coats contact surfaces with a riboflavin solution, once the CIP (clean-in-place) devices rinses the surfaces, any harboring trace amounts of contaminates will be illuminated by the ultraviolet light. This procedure allows us to guarantee 100% CIP coverage of the vessel and mixer.
Portability is often extremely important, JVNW is capable of fabricating portable vessels for steam sterilization, this includes the castors themselves. Please view photos #12-14 for images of a vertical portable vessel that lays horizontal during the steam sterilization process.
The Polishing Unit of JVNW is proud of their top-of-the-line electropolishing equipment. Powered by a 7500 amp/480 Volt DC rectifier.
RA or RAVE: Roughness Average, the measurement of the peaks and valleys of the stainless surface, is typically measured in micro inches. The process of electropolishing will improve the surface finish (RA) 10% to 20%. An RMAX measurement is a stricter measurement, measuring the highest peaks and lowest valleys and grading the finish on those measurements alone.
Problem met solution when JVNW’s creative engineering team crafted the telescoping shaft to accommodate a hinged top, thus requiring minimal clearance. The hinged shaft allows for disassembly of shaft and impellers without pulling drive from vessel. Seal assembly is attached not to mixer shaft, but to the quill shaft, for ease of maintenance and testing.

JVNW Patented Sanifoil
Sanifoil Patented Impeller
- The leading edge of the impeller is curved slightly upward,
effectively capturing the CIP spray and directing the solution
to the underside of the blade.
- The impeller-to-shaft union is strong, but abbreviated. The
strength is derived from its curved shape; the abbreviation has eliminated a common CIP shadow.
- The portion of the impeller closest to the hub is configured in
a CIP-friendly vertical position to offset the slower relative
speed near the center.
- The Sanifoil’s trailing edge is tapered to create an axial flow
pattern, causing robust agitation and a uniform velocity
across the length of the blade.
- The top surface of the hub is pitched for complete drainage
and to allow the cleaning surface to flow underneath the hub.
