NEW MULTI-CHANNEL HIGH EFFICIENCY

Home Back

Faggiolati Pumps SpA continues its commitment to energy saving and to the resolution of the different application problems with the new multi-channel "high efficiency" hydraulics

 

TECNICAL SPECIFICATIONS

Multi-channel open rotor with high hydraulic efficiency, with selfcleaning blade profile which, through a special adjustable suction flange with grooves, allows the expulsion of solids and also fibrous

1 Shafts grided down in ball bearings and mechanical seals seats, over-dimensioned respect to standard parameters of use.
2 Motor asynchronous threephase squirrel cage type, insulation class H(180°C). Dry motor, cooled by surrounding liquid. Protection degree IP 68. The motor is projected for continuous or intermittent operation, with a maximum of 15 starts per hour at regular intervals. The motor is projected for working with 5% maximum voltage unbalance between phases.
3 Ball bearings overdimensioned, life lubricated, maintenance free.
4 Oil chamber oil lubricates and cools the seals and emulsifies eventual water infiltrations.
This electric pump has two types of seals for a perfect insulation between the electric motor and the pumped liquid.
Upper seal: Ceramic/Graphite.
5 Lower seal: mechanical, silicon carbide.
6 Rotors: made with a special self-cleaning anti-clogging blade profile, they are designed to provide high hydraulic efficiency and low energy consumption.

 

APPLICATION
The submersible multichannel "high performance" pumps with self-cleaning blade profile can be used in almost any application; they are mainly used for the pumping of domestic effluent containing solids and fibrous materials, process water, civil and industrial sludge, waste water sumps in general.
