Wanner™ Hydra-Cell® seal-less chemical pumps are used worldwide in chemical processes for metering & dosing, pressure injection, liquid transfer and many other applications. Chemicals can be aggressive, corrosive, abrasive and non lubricating, all characteristics that make them difficult to pump. Hydra-Cell chemical pumps are available with a variety of liquid head materials and are compatible with the widest range of chemical fluids.

Hydra-Cell chemical pumps can handle corrosive, abrasive liquids, non-lubricating liquids and those containing solids, over a wide range of pressures and temperatures and with the unique check valve arrangement, handles liquids with suspended solids reliably.With no dynamic seals or packings, Hydra-Cell chemical pumps can run dry without damage and require minimal maintenance. 

In the IChemE Awards 2007 event, the pumps won recognition when Wanner's submission Hydra-Cell Metering Solutions was 'highly commended' by judges for the AMEC Award for Innovation and Excellence.

In metering and dosing applications, direct comparison with traditional metering pumps reveals lower costs for acquisition, energy consumption and maintenance, making the Hydra-Cell best in class for Life Cycle Cost. Its compact build, with multiple diaphragms integrated in a single pump head, produces a virtually pulseless flow. Resulting accuracies are better than required by API 675 performance criteria. Often there is no need for pulsation dampeners. The smooth flow also eliminates leaks that could occur in the discharge piping due to pipe strain.
