Definition Of Model
SZ50-32-160
SZ : Fluorin plastic centrifugal pump
50 : Suction diameter (mm)
32 : Drainage diameter (mm)
160 : Nominal diamter (mm) of impeller
Structure Feature
- SZ pump has one impeller, axial suction and radical discharge
- Simple structure, shaft is directly connected with impeller
- Easy for pipe, inlet and outlet are connected by standard flanges
- Wet parts are made of F26. F46, accessories are made of cast iron (HT200)
Typical application
- Any concentration of acid, salty solution, strong oxidants, organic solvent etc. Strongly corrosive medium
- Petrol chemical, pesticide, acid cleaning, dying, paper making galvanization, etc.
Operating conditions
- Thin medium not containing grain or 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
- TEFC motor 2 pole
- Protection class IP55
- Insulation level : 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 value of constant motor speed 2900rpm, 50Hz, 3 x 380V
- The measurement were made with airlines water at temperature of 20°C. The curves apply to a kinematic viscosity of 1mm2/s (1 cst)
- It is sugested to operate the pump in the scope of the bold curve, to prevent motor from overoad
- When pumping liquids with a density higher than of the operation conditions, use motors with correspondingly higher outputs
Performance curve
- Q/H : Means the curve of the flow and head at the nominal rotating speed
- Power curve : P2 means the pump input power, if the medium density is 1 x 10 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 frozem-free and ventilate place
- The electric protection devices should protect pump from being damaged by phase lack, unstable voltage, electric leakage overload
