Definition Of Model
SZ50-32-160
SZ : Fluorin plastic centrifugal pump
50: Suction diameter (mm)
32 : Drainage diameter (mm)
160 : Nominal diameter (mm) of impeller
Structure feature
- S2 pump has one impeller, axial suction and radical discharge
- Simple structure, shaft is directly connected with impeller
- Easy for pipe works, imlet and outlet are connected by standard flanges
- Wet parts are made of F26.F46, accesories are made of cast iron (HT200)
Typichal application
- Any concentration of acid alkali, salty solution, strong oxidants, orgnic 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
- TEEC motor, 2pole
- Protection class : IP 55
- Insultion : CLASS F
- Standard volatge : 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, 5oHz, 3 x 380V.
- The measurement were made with airless water at temperature of 20°C, the curves apply to a kinematic viscocity 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 flow and head at the normal rotating speed
- Power curve : P2 means the pump input power, if the medium density is 1 x 103 kg/m3
- Efficient curve : Eta means the pump efficient
Installation Conditions
- When installation, please make sure the pump would not be effected by the pipeline force when pump operation
- The pump should be strongly fixed on the horizontal base
- In order to make motor work well, pump should be installed on the frozen free and ventilate place
- The electric protection devices should protect pump from being damage by phase lack, unstable voltage, electric leakage, overload
