Design Features
- Horizontal / Vertical rigidly-coupled, volute casing, single stage, end suction centrifugal pump with closed impeller.
- Volute casing dimensions comply with EN 733.
- Complies EU547/2012 regulations.
- 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.
Pump Designation
- Pumps are rigidly coupled with electric motors of IEC frame sizes with high efficiency class.
- All impellers are balanced dynamically or statically according to ISO 1940 grade 6.3.
- 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.
- 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.
- 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.
- For ECO SNM and ECO SNM-V drawings, please look at www.standartpompa.com.
Shaft Sealing
- Depending on customer request or liquid type, mechanical seals are available.
