6tr Serise Submersible Pumps

Product Description

Typical applications
Water supply and irrigation system
Lowering underground water level
Booster
Various industrial applications
Working conditions
Solid grain-or-fiber-free dilute clean non-corrosive liquids;
Maximum liquid temperature: 20
Maximunm working pressure: 30 bar
pH: 6.5~8.5
Maxium diving depth: <=50m

Scope of application
This series is applicable to circulation and pressurizing of the clean water and softened water;
This series is made from stainless steel 304 and has good corrosive resistance for conveying cold water containing small amount of oxides. It is also used for conveying slightly alkaline water and de-mineralized water. Pump made from stainless steel 316 and FPM is applicable to conveying highly corrosive liquid.

Curve conditions
The curve tolerance complies with ISO9906 shown in attachment A.
All curves are based on the measured values of 3*380V, 50Hz, 2850r/min.
All measurements are carried out with gas-free water of temperature 20. The curve is applicable to kinematical viscosity 1mm2/s. In case density of the liquid conveyed by the pump is higher than that of water, it is necessary to use corresponding motor of higher output power.

The coarse part of the curve means the recommended performance scope.
The performance curce includes loss caused by check valve etc.
Performance curve
Q/H curve means flow and the curve of lifting height under the rated speed.
Power curve: P2 means input power of each grade
Efficiency curve: Eta means the grade efficiency of the pump
