SLZ(W) series low noise single-stage pump
The low-noise centrifugal pumps are new products made t- hrough a long-term development and according to the require- ment to the noise in the environmental protection of the new century and, as their main feature, the motor uses water-coo- ling instead of the air-cooling,which reduces the energy loss of the pump and the noise, really an environmental protection e- nergy-saving product of newgeneration. The range of performance of the low-noise pump isthe s- ame as that of model SLS and SLW available in this Co. and they are all developed per ISO2858. It includes four kinds: Model SLZ vertical low-noise pump; Model SLZW horizontal low-noise pump; Model SLZD vertical low-speed low-noise pump; Model SLZWD horizontal low-speed low-noise pump; For SLZ and SLZW,the rotating speed is 2950rpmand,of the range of
SLZ(W) series low noise single-stage pump
performance,the flow<300m3/h and the head<150m. For SLZD and SLZWD, the rotating speed is 1480rpm and 980rpm,the flow<1500m3/h,the head<80m. These pumps are used to transport pure water and the liqu- ids of the physical and chemical natures similar to pure water with the medium temperature under 95oC,cowgirl measure and other, if adoption heat the bearings,electrical engineering use paint lines,and the H class insulate the grade,can attain 150oC and suitable for industrial and city water supply, boost water supply for high buildings,air-conditioning,warming,fighting, circulated boost and so on. The aperture of the pump is available from 40mm to500mm, extensively meeting with various demands. To further save energy and close to the actual runningco- ndition,the outer diameter of the impeller of the pumps of each

specification may be cut per the actual running condition(with A,B,C shown next to the model). As of the voltage,those motors less than 1.1kw are220-380V and those more than 1.1kw are all 380V.
