Head: 11-300m;
Speed: 2850r/min;
Calibre: 150-400mm;
Medium temperature: ≤ 40 degreeC

Applications

1. Water supply and irrigation system
2. Lowering underground water level
3. Booster
4. Various industrial applications

Working conditions:

Solid grain-or-fiber-free dilute clean non-corrosive liquids;
Maximum liquid temperature: 35 deg C
Maximunm working pressure: 30 bar
pH: 6.5 to 8.5
Maxium diving depth: ≤ 50 m

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, 2850 r/min.
All measurements are carried out with gas-free water of temperature 20 deg C. 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

Motor of oil-filling type:

4"motor, single phase, maximum power up to 1.5. KW
4"motor, three phase, maximum power up to 7.5. KW
6"motor, three phase, power form 9.2KW to 37 KW
