Pumps cope with abrasive coatings
30 January 2017
Hydra-Cell seal-less pumps from Wanner have solved a pump seal wear problem for a major US producer of acoustic panels.

Replacing its pneumatic, single plunger pumps with Hydra-Cell G10 and G25 seal-less pumps not only solved a leak problem, it also greatly improved control over spray patterns and coating thickness.
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. The smooth flow also reduces pipework stress in the system The controllable, repeatable delivery (±1%) ensures the spray pattern is regular and the coating is consistent over time.
