Single-impeller centrifugal pump suitable for domestic, civil, industrial and agricultural systems, and for decanting, mixing and irrigation uses.
Construction Features of the Pump
- Pump body and motor support in cast iron.
- Technopolymer or cast iron impeller, as per the TECHNICAL DATA table.
- Carbon/ceramic mechanical seal.
Construction Features of the Motor
- Closed asynchronous type, external ventilation cooling.
- Rotor running on ball bearings, oversized to ensure low noise and durability.
- Standard built-in thermo-amperometric protection. Capacitor permanently fitted on single phase versions.
- For the protection of the three-phase motor, we recommend the use of remote overload cut-outs, in compliance with current local regulations.
- Construction according to CEI 2-3.
- IE2 motors as standard, from 0,75 kW to 5,5 kW - IE3 ≥ 7,5 kW
- From 1,8 to 96 m3/h, with head up to 62 metres.
- Clean, free of solids and abrasives, non-viscous, non-aggressive, non-crystallised and chemically neutral, with properties similar to water.
