EN733 электрический водяной насос из Китая

Brief Description EAZ series are derived from EA series according to the European Standard BS EN733/ DIN24255 of performance. Pump shaft and motor shaft are close-coupled design. This way of coupling 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. EAZ S, EAZ B, EAZ N are designed to be driven by IEC standard motor, and EAZ S, EAZ B can be assembled separately without motor; EAZ E requires a special motor with extra-long shaft. Compared by EA pump direct-coupled with motor, EAZ series are much shorter in length thus takes less space to install; and they also can be adjusted into different performance levels through impeller trimming as EA. They are also used for pumping clean water or liquids similar to water, finding great application in industry, city water supply, construction, long-distance transportation, air-conditioning, firefighting and irrigation.
