HAZ Pump shaft and motor shaft are close -coupled design. This way of couplig ensures the alignment of pump and motor . PUMP impeller runs in good balance both dynamically and statically .Therefore pump would be kept very well in operation. HAZ S, HAZ B, HAZ N, are designed to be driven by IEC standard motor , and HAZ S , HAZ B can be assembled separately without motor ; HAZ E requires a special motor with extra - long shaft .Compared by HA pump direct -coupled with motor , HAZ series are much shorter in length thus takes less space to install ; and they also can be adjustd into different performance levels throught impeller trimming as HA ,
They are also used for pupping clean water or liquids similar to water . finding great application in industry , city water supply , construction , long -distance transportation , air -conditioning firefighting and irrigation . |
