Submersible electropumps
The ultimate pumps for waste water and purification equipment, with single channel closed impeller.

Submersible electric pump HM, thanks to their tough construction and the single channel closed impeller, that offers reliability against clogging and features wide through sections and a good resistance to wear, low mechanical action on the fluid, high hydraulic efficiency, is particularly suitable for clean water, water containing solid and fibrous solids, cloacal water, sewage and sludge.

Is possible the submersible fixed installation with the automatic coupling foot or the mobile installation with base support.

Motor asynchronous squirrel cage type in dielectric anti-oxide oil bath, protectin degree IP 68 and insulation class F. Single-phase feeding: motor protector and capacitor in box control. Three-phase feeding: with compulsory protection to be provided by the user.

Motor housing cast iron GG 25, shaft stainless steel AISI 420, electric cable neoprene H07RN8-F, bolt A2 class AISI 304, O.rings nitrile. Shaft sealing by two mechanical seals mounted in series in ecologic oil chamber. Seal types applied to the motor side on ceramic/graphite and seal types applied to the wet end side on silicon carbide.

Conductivity sensor and thermal probes on request.
