Cleanroom Utility Systems
Sanitary Centrifugal Pump
A close-coupled 316L centrifugal pump for efficient circulation and transfer of clean utility water and low-viscosity hygienic liquids.
- Polished 316L wetted parts
- Low-hold-up hygienic wet end
- Single or flushed double seal options
Product Introduction
The sanitary centrifugal pump combines a polished stainless volute and impeller with a close-coupled electric motor for compact clean-utility service. The open hygienic wet-end geometry supports effective cleaning, while external seal access simplifies inspection and replacement without disturbing facility piping more than necessary.
Key Features
Single-stage end-suction hydraulic design
Polished hygienic volute and impeller
External single or double mechanical seal
Close-coupled compact footprint
Sanitary clamp or weld-end connections
Optional stainless motor shroud
Drainable installation orientation
Customer Product Concerns
Reliable hygienic pumping requires the hydraulic curve, seal arrangement and installation geometry to match both normal operation and cleaning conditions.
The pump operates far from its efficient rangeSelect impeller diameter and motor speed from the actual system curve rather than pipe size alone.
Seal wear causes recurring leakageChoose seal materials and single, flushed or double configuration according to temperature, lubricity and cleaning exposure.
Air pockets interrupt stable circulationProvide flooded suction, adequate NPSH margin and ventable piping for a standard non-self-priming centrifugal pump.
Residue remains in the wet endInstall the pump in its specified drainable orientation and maintain the defined cleaning velocity through the casing.
Typical Applications
Purified Water circulationWFI distribution supportCIP solution transferPharmaceutical buffer transferBiotechnology and cosmetic process utilities
