Hygienic centrifugal pump - TRA400
Wright Pump's TRA 400 series centrifugal pumps' robust design and high quality materials of construction make it the right choice for both high-purity and ultra hygienic fluid transfer.
Ultra-pure centrifugal construction comes from wetted parts entirely machined from solid 316L stainless steel forged bar and plate or other high quality alloys. The forged materials are very low in ferrite which is commonly associated with causing rouging in high purity water systems. The TRA400 series' fully adjustable head orientation provides unmatched installation flexibility. Standard seal materials are silicon carbide and USP Class VI elastomers.
The TRA400 series' patented Softsterile™ seal flushing system uses exclusive straight-line internal seal flushing with fully drainable flow paths you can easily inspect. The Softsterile™ flushing eliminates the external piping, fittings, gaskets, elbows, tees and other components that may be misaligned, leak or not be fully drainable.
The TRA400 series also eliminates the “dead leg” found in other centrifugal pumps due to its unique diaphragm valve body machined directly into its casing. This permits a flush face fit with the pumps’ interior contour, allowing the diaphragm to be swept continuously with product during operation to achieve true Zero Dead-Leg casing drain. The patented Zero Dead-Leg drains are a half-inch in diameter; larger sizes are available upon request.
Each TRA400 series pump comes with extensive installation qualification (IQ) supporting documents such as test reports, performance curve, surface finish and welding certificates of conformance, material certifications, motor data, suggested spares and build specifications.
Typical Applications:
- Pure Water Systems: Water for Injection (WFI), RO, DI, USP, process water. Non-shear sensitive products requiring the highest hygienic control. Compendial water recirculation loops.
- Ultra Hygienic: food, beverage, dairy or other hygienic processes where the highest level of quality and supporting material documentation is required.
