Typical application
- S2 pump has one impeller, axial suction and radical discharge
- Simple structure, shaft is directly connected with impeller
- Easy for pipe work, inlet and outlet are connected by standard flanges
- Wet parts are made of F26, F46, accessories are made of cast iron (HT200)
Typichal application
- Any concentration of acid alkali, salty solution, strong oxidant, organic solvent etc. Strongly corrosive medium
- Petrol, chemical, pesticide, acid, dying paper making, galvanization, etc
Operation Conditions
- Thin medium not containing grain of fiber
- Medium temperature : -20°C – 120 °C
- Medium density. Max 1.35 x 10 kg/ m3
- Ambient temperature Max + 40°C
- Altitude Max. 1000 m
- Pressure Max . 10 bar
Motor
- TEEF motor, 2pole
- Protection class : IP 55
- Insulation : Class F
- Standard voltage : 50 Hz, 3 x 380V
Curve Conditions
- Curves tolerance is according to ISO9906, Annex A
- All curves are based on the measured valve of constant motor speed 2900 rpm, 50Hz, 3 x 380 V
- The measurement were made with airless water at temperature of 20°C, the curves apply to a kinematic viscosity of 1 mm2/s (1 cst)
- It is suggested to operate the pump in the scape of the bold curve, to prevent motor from overload
- When pumping liquids with a density higher than that of the operation conditions, use motors with correspondingly higher outputs
Performance Curve
- Q/H : means the curve of the and head at the normmal rotating speed
- Power curve : P2 means the pump power, if the medium density is 1 x 103 kg/ m3
- Efficient curve : Eta means the pump efficient
Installation Conditins
- When installation, please make sure the pump would not be effected by the pipeline force when pump operation
- The pump should be strongly fixed, pumps should be installed on the frozec free and ventilate place
- The electric protection devices should protect pump from being damage by phase lack, unstable voltage, electric leakage, overload
