Features and applications
Submersible electric pump QM, thanks to their tough construction and the single channel opened 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 4 poles on three-phase squirrel cage type in dielectric anti-oxide oil bath, protectin degree IP 68 and insulation class F.
Motor housing Cast iron GG 25, shaft stainless steel AISI 420, electric cable neoprene H07RN8-F with free therminals, bolt A2 class AISI 304, O.ring 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.
