KONTRA-2 Bronze Pump - 1250 230/400V BRONZ
1 665,81 € exc. VAT
The first robust plastic pump delivering the performance of a cast iron or bronze pump. The impeller is made of Noryl plastic, the pump body and the glass-fiber reinforced polypropylene diffuser provide outstanding durability. A large pre-filter together with excellent hydraulic performance guarantees an extremely high filtration capacity. A transparent polycarbonate cover with four closures for easy pre-filter inspection. The stainless steel (AISI 316) pump shaft is not in contact with the pumped water - it also works with salt and seawater when equipped with an AISI 316 mechanical seal. Motor bearings with lifetime lubrication for long life and quiet operation - lower RPM = lower noise and wear = longer life compared to standard pumps. Lower operating temperature of the motor, IP 55 motor protection. Flange connections Ø 110 mm (flange not included).
Each unit is tested (it has its own traceable "birth" with measured technical data attached to the back of the manual)
