| Model Definition SZ50-32-160 SZ is Fluorin plastic Centrifugal Pump 50 is suction diameter(mm) 32 is drainage diameter(mm) 160 is nominal diameter(mm) of impeller 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. Structure feature ·SZ 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) Operation conditions Thin medium not containing grain or fiber. Medium temperature: -20 ~ 120 ; Medium density: Max 1.35×103kg/m3Ambient temperature: Max+ 40 Altitude: Max 1000m Pressure: Max 10bar 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. Motor ·TEFC motor, 2 pole. ·Protection class: IP55 ·Insulation level: CLASS F ·Standard voltage: 50HZ, 3×380V Curve notes The following notes are for the curves in the following. ·Curve tolerance complies to ISO 9906, appendix A ·All the curves are based on the motor of constant speed 2900rpm, 50HZ, 3×380V ·The pumps were tested with 20 non-air water, kinematic viscosity is 1mm 2 /s. ·It is suggested to operate the pump in the scope of the bold curve, to prevent motor from overload. ·If the density of the pumped liquid exceeds the density of the operation condition, appropriate bigger power motor should be used. Performance curve Q/H: means the curve of the flow and head at the nominal rotating speed. Power curve: P2 means the input power if the medium density is 11×103kg/m3Efficient curve: Eta means the pump efficient. |
