A mag-drive pump that handles suspended solids

By Gerald Ondrey |

In critical pumping applications involving toxic or expensive products, the use of double mechanical seals or external flushing fluids can lead to product contamination or leakage, as well as additional costs for installation and monitoring. Although hermetically-sealed pumps, such as magnetically-driven (mag-drive) pumps can prevent such problems, mag-drive pumps run into problems when pumping fluids with suspended solids, says Mario Monza, export sales manager at CDR Pompe S.r.l. (Bollate, Italy; www.cdrpompe.com). CDR Pompe has resolved this drawback, with its newly developed XTN-XTS pump series, which will formally be launched at next year’s Achema trade fair. The XTN-XTS series features a patent-pending, dynamic-shaft design with an open style impeller, which allows solids to circulate inside the pump, explains Monza. All passages between static and rotating parts are designed — using strategically located pressure differences inside the pump — to avoid resistance to circulation and accumulation of solid particles (diagram). A “generous” axial canal on the pump shaft eliminates axial-thrust forces, and allows for the circulation of solids. Finally, diamond-coated SiC bushes are used to protect from dry-running and increase…
