Mono Pumps Enables Swedish Pulp & Paper Producer to Increase Capacity

A pulp & paper producer in Sweden was faced with a need to increase the capacity to pump coating compound from a storage vessel out to a paper coating machine at their Stockholm plant. The company contacted a local distributor, AxFlow, to find a pumping solution. On Axfow’s recommendation, the pulp & paper producer purchased two Mono E-Range progressing cavity (PC) pumps to be used in conjunction with the existing Mono equipment in use at the plant in Stockholm.

“The coating compound involved is extremely abrasive and highly viscous,” says Hans Lundkvist, AxFlow’s Sales Engineer in Sweden. “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.”

Coating clay in pulp & paper applications is highly shear sensitive and can contain up to 75% solids, including kaolin, marble, carbonates and titanium oxide. It can also dry instantly, making it essential that the pumps used can prevent moisture loss, while still providing a gentle pumping action to avoid shear damage to the coating clay during transfer. PC pumps are ideal for this type of application.

The vertically-mounted high pressure Mono E-Range pumps are reliable and efficient in applications handling particularly abrasive or viscous fluids. The pumps are designed with a helical rotor turning within a resilient rubber stator, which provides a smooth low shear action. The pumps also feature Mono’s unique Flexishaft drive system. This system provides a single component link between the rotary motion of the drive shaft and the eccentric motion of the helical rotor.
