In metering and dosing applications, from initial process stages to water treatment plants, the WANNER Hydra-Cell pump has a number of advantages over traditional metering pumps:

  • Compact design - saving installation space 
  • Save on acquisition costs
  • Reduced energy consumption and lower maintenance costs - lowering total life cycle costs
  • Extremely low pulse flow

Critical for Flow Chemistry and HPLC applications, the Hydra-Cell pumps deliver an extremely low pulse flow, without the need for pulsation dampeners, and with a predictable and controllable flow rate for a consistent process.

Seal-less design (the pump has no dynamic seals in contact with the process liquid) means that non-lubricating solvents and liquids containing suspended particles can be pumped reliably at pressure in HPLC (High Pressure Liquid Chromatography), ultrafiltration, nanofiltration, reverse osmosis and ultra-high pressure reverse osmosis systems.  

Hydra-Cell pumps are available with tri-clamp hygienic connections and polished internal components to 0.4 Ra.

Pilot plants used in process development and production installations for handling the waste stream are typical applications.
