Wanner Engineering Inc

Wanner™ Pharma-Pro™ seal-less pumps offer continuous process control with steady-state accuracy.
Wanner Pharma-Pro seal-less pumps deliver a wide, adjustable flow range with extremely low pulse flow, critical for consistent process control in applications such as Flow Chemistry and HPLC (High Performance Liquid Chromatography). Low-shear pumping action and ±1% steady state accuracy offers predictable and controllable flow rates. Unique multiple-diaphragm and seal-less pump design has no dynamic seals in contact with the process liquid, so non-lubricating solvents, shear-sensitive liquids, and liquids containing suspended particles can be pumped reliably at pressure in HPLC, ultrafiltration, nanofiltration, reverse osmosis and ultra-high pressure reverse osmosis systems. A leading innovator of seal-less pump technologies, Wanner pumps are relied upon in a wide range of critical processes and demanding industrial applications worldwide.
