Faced with the need to increase the capacity to pump coating compound from a storage vessel out to a paper coating machine, the customer approached pump solutions provider, AxFlow, who are a distributor of Mono products in Sweden.

“The coating compound involved is extremely abrasive and highly viscous,” says AxFlow’s Sales Engineer in Sweden, Hans Lundkvist. “This meant that the pumps chosen had to be rugged enough to provide reliable performance and we know that Mono’s E-Range pumps would work perfectly as they are well proven in this type of application. As the customer already had a number of vertically mounted Mono pumps installed and was very satisfied with their performance, a pair of Mono E-Range belt-driven pumps were the obvious choice when they needed to increase capacity. The fact that they could be vertically mounted was another added benefit, as floor space was limited with this particular application.”

The vertically-mounted high pressure E-Range pumps offer outstanding reliability and efficiency for applications where particularly abrasive or viscous fluids are being handled. They incorporate a helical rotor turning within a resilient rubber stator, providing a smooth low shear action which ensures the integrity of the coating mix remains intact. The pumps also feature Mono’s unique Flexishaft drive system that provides a single component link between the rotary motion of the drive shaft and the eccentric motion of the helical rotor. The reduced number of moving parts in the drive train eliminates wear and makes lubrication unnecessary, eliminating the risk of contamination. The Flexishaft design extends routine maintenance intervals and carries a 10-year warranty.
