CENTRIFUGAL PUMP TYPE NMW6 Code: 0785NBA815844
DN100 PNEUMATIC BY-PASS VALVE Code: 0785NBA815877
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.
Housing and impeller in aluminium alloy casting
Suction adapting flange in aluminium alloy casting
Gearbox case in aluminium alloy casting
Shaft in high resistance steel
Seals suitable for aviation fuel grades.
Connecting flanges are according TW standards: sucion flange DN 150, delivery and by-pass DN 100.
NMWS pump is easy to instal fixing only two supports.
On customer specific request, special seals can be mounted to work at lower temperatures (T = - 40 °C).
Nuova Manaro NMW6 pump in suitable to install the Nuova Manaro DN 100 PNEUMATIC BY-PASS VALVE.This item is manufactured in aluminium alloy casting with internal seals made in viton and PTFE, and it allows , by the correct regulation of the air supply pressure, to optimize the performances of refuelling systems of aviation fuel grades; It allows to regulate the refuelling pressure after the pump and it works also in the case of sudden surge pressure peaks or sudden valve closing in the refuelling system.
