Description

The pump type NMW6 by Nuova Manaro is a self-priming centrifugal pump suitably designed an manufactured to work in fixed and mobile systems for aviation fuels pumping.

The type and the particular shape of the impeller, and the gerabox designed with a suitable transmission ratio, give to the pump delivery performances from ~1500 LPM ( absorbing about 45 kW of power) to ~4000 LPM ( absorbing about 90 kW of power). At the described performance conditions, the pump is capable of 8 bar of prevalence.

Pump driving can be performed by hydraulic motor directly mounted on the gearbox case, or by mean of a cardan shaft requiring the suitable mounting assembly. To obtain the described performances, the pump command shaft totates from a minimum of 1500 rpm at a maximum of 2100 rpm.
