Pumps feature flow pattern to minimize internal friction losses

Don Horne   

Vissers Sales offers these air operated double diaphragm pumps with an innovative flow pattern to minimize internal friction losses. These design features ensure that the compressed air is only used to move the liquid and not to compensate for friction losses. Maintenance costs are significantly reduced for many fluids because in the event of a diaphragm failure, the air drive system is not contaminated or in need of extensive cleaning or replacement. Air is prevented from entering the fluid being pumped, so critical applications where air mixed with the transfer fluid would degrade the final product can be performed reliably even in the event of diaphragm failure.
