Termomeccanica Pompe MES & MESD pumps are between bearings, single casing, radially split, and multistage with a diffuser design.
Suction and discharge covers are center-line mounted. Casings are pressed together by external tie bolts and sealed by confined o-rings. The MESD model has a first stage double suction impeller for low NPSH applications. Top-top suction and discharge nozzles are standard. Hydraulic axial thrust is compensated by a balancing disk or balancing drum. A bleed off nozzle can be provided. The bearing design depends on the type of axial thrust balancing system. A special product lubrication bearing design is available for high pressure reverse osmosis service.
