MNR and MND Overhung Absorber Recirculation Pumps
MNR and MND Overhung Absorber Recirculation Pumps
| Brand: | Flowserve |
|---|---|
| Description: |
The MNR and MND pumps are overhung end suction centrifugal pumps specifically developed for absorber recirculation in flue gas desulfurization (FGD) systems. Designed for continuous-duty operation in abrasive and corrosive slurry environments, these pumps provide reliable performance in power generation and industrial gas scrubbing applications. The MNR model features a radially split casing with top suction and top discharge nozzles for simplified piping and maintenance. The MND variant includes a volute casing design with side suction for flexible layout options. Both designs offer large solids passage, thick wear-resistant components, and are available in rubber-lined or high-chrome iron construction to extend pump life in harsh conditions. With high efficiency low maintenance requirements and excellent hydraulic stability the MNR and MND pumps are trusted in FGD systems around the world. |
Reflecting its commitment to making flue gas desulfurization (FGD) systems more effective, Flowserve developed the rubber lined MNR and metallic MND absorber recirculation pumps. Built upon the proven design and hydraulics of the Flowserve MN solids-handling pump, the MNR and MND pumps are renowned for their high efficiency and versatility.

High Efficiency Impeller is one piece design with no exposed threads. Mixed flow vane design is highly efficient at hydraulic conditions found in recirculation services. Multiple materials choices permit maximum wear life in corrosive and erosive environments.
Replaceable Casing Wear Ring extends casing life and is available in many corrosion and abrasion resistant materials.
Opposed Tapered Roller Bearings firmly support the shaft, virtually eliminate axial and radial thrust loads, and are designed for a minimum B10 life of 100 000 hours.
MNR’s Radially Split Casing provides access to the impeller. Tangential discharge provides unobstructed flow path and extends wear life.
MNR’s Removable One Piece Elastomeric Liner protects against wear and allows for both front and back pullout.
Features:
- Product flush slurry seal
