ECO SNM PUMPS
2- GENERAL PUMP DESCRIPTION
2.1- Pump Description
• ECO SNM series pumps are horizontal, radially split volute casing, single stage, end suction centrifugal pumps
with closed impeller.
• The dimensions of volute casing comply with EN 733.
2.2- Application Areas
ECO SNM series pumps are suitable for clean or slightly contaminated (max. 20 mg/dm
3
) liquids with low viscosities
and temperatures up to 140 º C . The main application areas, among others, are:
• Water supply, water treatment and irrigation systems,
• Heating, chilled and cooling water systems,
• Water systems for industrial uses,
• Industrial circulating systems,
• Fire fighting,
• Power plants.

Pump performance curves, including efficiency characteristics: see documented characteristic curve
The efficiency of a pump with a trimmed impeller is usually lower than that of a pump with full
impeller diameter. Trimming of the impeller will adapt the pump to a fixed duty point, leading to
reduced energy consumption. The minimum efficiency index (MEI) is based on the full impeller
diameter.
Operation of this water pump with variable duty points may be more efficient and economic when
controlled, for example, by the use of a variable speed drive that matches the pump duty to the
system.
