Abrasive tile coatings
Published: 25 November, 2016
WANNER says its Hydra-Cell seal-less pumps, have solved a pump seal wear problem for a major producer of acoustic panels. When pumping abrasive coatings, pumps with dynamic seals can eventually wear and leak, performance accuracy deteriorates and maintenance downtime for seal replacement can prove expensive as the Corporation found to its cost.
Wanner says replacing the pneumatic, single plunger pumps with Hydra-Cell G10 and G25 seal-less pumps not only solved the leak problem but also greatly improved the control over spray patterns and coating thickness and with no dynamic seals to wear, the Hydra-Cell pumps are able to pump the abrasive coating material reliably and require minimal maintenance. Having multiple, hydraulically balanced diaphragms in a single pump head, the Hydra-Cell pumps produce a smooth pulseless flow without the need for pulsation dampeners.
