Pumps can run dry indefinitely

Pumps failing through running dry is not an uncommon problem but one that can be eliminated, says Wanner, using Hydra-Cell seal-less pumps. These high pressure pumps operate with hydraulically balanced diaphragms and therefore have no dynamic seals to overheat and fail during dry running. Wanner claims the pumps can run dry indefinitely without problem. Hydra-Cell's sealless design also enables them to pump liquids that contain abrasive particles and other non-lubricating fluids.

Operators too busy to notice that the feed tank is empty cost industry many millions of pounds each year, money that could be saved, says Wanner, by using Hydra-Cell pumps.
