Cast iron single impeller centrifugal electric pumps
CM series electric pumps are single impeller electric pumps with cast iron body. Within the series there are several models: CMA – CMB – CMC – CMD and the CMR model that has the peculiarity of being equipped with an open impeller. They are equipped with a mechanical seal in Ceramic/Carbon/ NBR. Depending on the models, the impellers can be made of PPE + PS reinforced with fibre glass, brass or cast-iron. The shafts can be in AISI 416, AISI 303 steel or, alternatively, in AISI 304. The supports available are in aluminium or cast iron. The motors combined with these electric pumps are 2-pole self-ventilated asynchronous motors and IE3 high efficiency starting from 0.75 kW.
