An industrial coatings manufacturer complained that their helical rotor pumpsets kept running dry, blocking up and failing. Each incident was not only causing downtime and a costly repair, but there was the added risk of the plant over-flowing and causing an environmental disaster.
All Pumps suggested a Wilden Brahma 2” AOD pump, which is able to run dry and cut down cost since it is powered by air.
The pump was mounted on a trolley, with pneumatic tyres, for mobility. The pump was placed into service at the next failure and has been there ever since!
