812,46 € exc. VAT
First rugged plastic pump achieving the properties of a cast iron or bronze pump. The impeller made of Noryl plastic, the pump housing and the glass-reinforced polypropylene diffuser provide exceptional durability. The large pre-filter together with excellent hydraulic performance guarantees an extremely high filtration capacity. The 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 can operate with saline and seawater when equipped with an AISI 316 mechanical seal. Motor bearings with lifetime lubrication for long life and quiet operation - lower speeds = lower noise and wear = longer life compared to standard pumps. Lower operating temperature of the motor, motor enclosure IP 55. Flanged connections Ø 110 mm (flange not included).
Each unit is tested (it has its own identification "birth" with measured technical data, attached on the back of the manual)
