The low-noise centrifugal pumps are new products made through a long-term development and according to the requirement to the noise in the environmental protection of the new century and, as their main feature, the motor uses water-cooling instead of the air-cooling,which reduces the energy loss of the pump and the noise, really an en vi ronmental p rotectione -
nergy-saving p roducto f n ew generation.
The range of performance of t he l ow-noise pump i s the same 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;
F or S LZ a nd S LZW,the rotating s peed is 2 950rpm and,of
3 the range of performance,the flow 300m /h and the head 150m.
For SLZD and SLZWD, the rot at ing spe ed is1480rpm and
3 980rpm,the flow 1500m /h,the head 80m.
These pumps are used t o t ransport pure water and the liquids of the physical and chemical natures similar to pure water
