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
- SZ pump has one impeller, axial suction and radical discharge.
- has one impeller, axial suction and radical discharge.
- 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).
Typical application
- Any concentration of acid alkali, salty solution, strong oxidants, organic solvent etc. Strongly corrosive medium.
- Petrol, chemical, pesticide, acid cleaning, dying, paper making, galvanization, etc.
Operation conditions
- Thin medium not containing grain or fiber.
- Medium temperature: -200C – 1200C
- Medium density: Max 1.35 x 103kg/m3
- Ambient temperature: Max + 400C
- Altitude: Max 1000m
- Pressure: Max 10 bar
Motor
- TEFC motor, 2 pole
- Protection class: IP 55
- Insulation level: CLASS F
- Standard voltage: 50Hz, 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 measurements were made with airless water at temperature of 200C . The curves apply to a kinematic viscosity of 1mm2/s ( 1 cst )
- It is suggested to operate the pump in the scope 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 nominal rotating speed.
- Power curve: P2 means the pump input power, if the medium density is 1 x 103kg/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 damaged by phase lack, unstable voltage, electric leakage, overload.
