Product Specification Sheet RIGIDLY COUPLED CENTRIFUGAL PUMPS Handled Liquids Clean or slightly contaminated low viscosity liquids without solid & fibrous particles. •All impellers are balanced dynamically or statically according to ISO 1940 grade 6.3. Technical Data Discharge Flange Operating Temperature Casing Pressure (Pmax) •Axial thrust is balanced by impeller balancing holes system. •Direction of rotation is clockwise viewed from drive end. •In case of request, wear ring and/or shaft sleeve can be supplied. (Pmax: Suction Pressure + Shut off Head) (*) Contact company for higher capacity and head values. (**) The Material of pump differs according to the type of pumped liquid, operating temperature and pressure. Contact for detailed information. Design Features •Horizontal / Vertical rigidly-coupled, volute casing, single stage, end suction centrifugal pump with closed impeller. •Rigidly coupled pumps are lighter and smaller comparing to the norm centrifugal pumps of same hydraulic specifications. •When the elbow is mounted on the suction of the pump, the name is changed to ECO SNM-V. In this case, the pump is always installed verticaly. •The electrical motor powers of ECO SNM-V pumps are limited because of its installation type. •Volute casing dimensions comply with EN 733. •Suction and discharge flanges conform to EN 1092-2 / PN 16. The flanges are according to EN 1092-1 / PN 16 for steel or stainless steel casing. In case of request, ANSI/ASME flanges can be supplied. •Pumps are rigidly coupled with electric motors of IEC frame sizes with high efficiency class. Pump Designation •The pump and motor have seperate shafts connected by a rigid coupling or through slide fit shaft. Axial and radial forces are absorbed by electric motor bearings. •For ECO SNM and ECO SNM-V drawings please contact us Shaft Sealing •Depending on customer request or liquid type, mechanical seals are available.
