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, 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 oxidants, 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
- Abient temperature max +40°C,
- Altitude max. 1000 m
- Pressure max . 10 bar
Motor
- TEEC motor, 2pole
- Protection class : IP 55
- Insultion : Class F
- Standard voltage : 50 Hz, 3 x 380V
Curve Conditions
- Curcves tolerance is according to ISO9906, Annex A
- All curves are based on the measured valve of constant motor speed 2900 rpm 50Hz, 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 output
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
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 deviates should protect pump being damage by phase lack, unstable voltage, electric leakage, overload
