Product Specification Sheet SNM / SNM-V RIGIDLY COUPLED CENTRIFUGAL PUMPS Handled Liquids Clean or slightly contaminated low viscosity liquids without solid & fibrous particles. Technical Data Discharge Flange Motor Rating Operating Temperature Casing Pressure (Pmax) •SNM / SNM-V pumps are rigidly coupled with electric motors of IEC frame sizes with high efficiency class. •All impellers are balanced dynamically according to ISO 1940 class 6.3. •Axial thrust is balanced by impeller balancing holes system. •Direction of rotation is clockwise viewed from drive end. (Pmax: Suction Pressure + Shut off Head) •The pump and motor have seperate shafts connected by a rigid coupling and motor bearings absorb all pump axial thrust loads and radial loads. (*) Contact for 75 kW and 90 kW options (**) The Material of pumps differ according to the type of pumped liquid, operating temperature and pressure. Contact for detailed information. •SNM / SNM-V type close-coupled pumps are lighter and smaller comparing to the norm centrifugal pumps of same hydraulic specifications. Design Features •Horizontal / Vertical Close-coupled, volute casing, single stage, end suction centrifugal pump with closed impeller. •Main dimensions of volute casing complies with EN 733. Shaft Sealing •Single mechanical seal, flushed by pumped liquid, uncooled and unbalanced. •Suction and discharge flanges conform to EN 1092-2 / PN 16.
