High-speed paper processes demand reliable and consistent pumping systems.

In duties ranging from paper coating and preparation to high pressure cleaning, wet-end trimming, spraying of glues and waxes, and extremely accurate metering (exceeding API 675 standards for metering pumps) the reliability of Wanner™ Hydra-Cell® Pro seal-less pumps is well-proven in the paper industries.

Hydra-Cell Pro pumps reliably handle recycled water, abrasive fluids, fluids with solids in suspension, chemicals, non-lubricants and many other difficult liquids. Many of the fluids used are abrasive and react with air to crystallize or harden, which can cause problems with pumps that have mechanical seals. Hydra-Cell Pro's seal-less pump design eliminates this problem entirely.

High pumping efficiency when compared with multi-stage centrifugal pumps is enabling mills to make significant energy savings on trim cutting, cleaning and other high pressure water applications, while also reducing maintenance and repair costs.

On coating processes, Hydra-Cell Pro’s seal-less design and virtually pulse-less flow, combined with vertically oriented check valves, enable liquids containing suspended particles to be applied consistently and reliably.

With multiple diaphragms in a single head, the compact design of Hydra-Cell Pro pumps offers advantages of reduced bulk and footprint of traditional metering pumps of equivalent flow and pressure capability. Saving installation space is not the only benefit. Other advantages include lower costs of acquisition, energy consumption, maintenance and repair – for example pipe repair due to pipe strain often seen with single-diaphragm metering pumps.
