STC直联泵 开式叶轮

STC
Open Impeller Centrifugal Pumps开式叶轮离心泵

STC单叶轮泵
该泵低扬程的特性使得它特别适用于农业用途。本泵型用于灌溉以及几乎所有要求高流量低扬程的场合。每台泵在组装后根据ISO9000标准的质量要求进行液压与电气试验。
STC single impeller centrifugal pumps with low delivery pressure are specially conceived for agricultural applications. This type of pump is necessary in sliding irrigation and in general in all those applications where high flow rates at low delivery pressures are required. At the end of assembly each pump is hydraulically and electrically tested in accordance with ISO9000 quality requirements.
