Product Overview
These units have a very extensive range of applications for lifting and distribution in domestic and industrial water systems, filling of pressure vessels and tanks, pressure booster and irrigation systems. MICRA HS is composed by a three-phase submersible pumps and driven by a sigle phase inverter (ACTIVE DRIVER). Pump construction features Multi-stage centrifugal type. Directly coupled pump and motor with rigid coupling. Impellers and thrust rings in Noryl and diffusers in self-lubricating polyacetal.



Pump liner, shaft with coupling, filter and cable cover in stainless steel. Base support and head in brass with check valve incorporated in head. Motor construction characteristics Submerged asynchronous two-pole motor made entirely of AISI 304 stainless steel with brass supports. Squirrel cage rotor in copper mounted on Kingsbury thrust block. Cooling of the thrust bearing assembly and the bushings is provided by water, thereby eliminating the risk of contamination.
