WLT,WLTS,WLTSF Horizontal Cooling Tower Pump

Horizontal Cooling Tower Pump

Structure features

Non-self-priming,single stage, single suction, horizontal;axial suction and radical discharge

Motoris fixed by base, easy to install.

The back pull pattern structure makes it easy to repair

WLT pump shaft and motor shaft are coaxial connection,small occupation area, light weight;WLTS and WLTSF adoptthe structure oflengthened shaft with straight connection.

lmpeller and casing adopt excellent hydraulic model, theycan be designed according to market

Key components such as impeller and shaft are made ofstainless steel

Casted by resin sand,the castings feature smooth andbright surface, nice shape, good quality, dense structure.

Precision casting technique is applied in WLTSF pump`sflow passage component, which achieves a smooth interiorand exterior of pump passage component and reduces theroughness.

Applications

Water circulation of closed cooling tower and condenser;cooling of various unit equipment ; circumstances in whichneed pump with large flow and low head.

Clean,thin,non-corrosive,non-flammable ornon-explosiveliquid without solid grain or fiber which won't attack the pumpchemically or mechanically Liquid with high viscosity or bigdensity will result the decrease of performance curve andthe increase ofenergy consumption.

Liquid temperature:-15°~100'C

Max.ambient temperature:+40C

Max.working pressure: 6 bar

Motor

Totally closed fan cooled motor

Protection level:lP55

Insulation level:F

Standard voltage:50Hz:1x220V

                                      3x380V

                            60Hz:3x460V

Curve conditions

Following conditions are suitable for performancecurve

All curves of50Hz frequency are based on themeasured values ofvoltagein 3x380Vand constantmotor speed at 2900rpm or 1450rpm; All curvesof 60Hz frequency are based on the measuredvalues of voltage in 3x460V and constant motorspeed at 3450rpm,3500rpm,1750rpmor 1770rpm.

Test mediumis clean water with temperatureof 20 ℃ without any solid impurity and air.

The operation of pump should refer to theperformance range of curve shown in boldface toprevent overheating due to too small flow rate oroverloading due to too large flow rate.
