Features and applications
Submersible electric pump QV, thanks to their tough construction and the vortex impeller, that offers reliability against clogging due to the feature of wide through passages, and a good resistance to wear thanks to the absence of shimming, versatility of use compensates somewhat lower efficiency, is particularly suitable for water containing a large amount of solids and long fibre, raw and waste waters, stirred and raw sludge, rotten sludge, mixed waters.
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 oil chamber.
Seal types applied to the motor side on cer./graphite, seal types applied to the wet end side on silicon carbide.
Conductivity sensor and thermal probes on request.
