Pumping Sugar Mass and Magma in Sugar Cane Plants

with NEMO® pump

NEMO® pump


NEMO® PUMP FOR MAGMA:APPLICATION MAGMA AT AN OPEN TANK:-Temperature: 55-60° C;-Density: 1,5-Viscosity: up to 200.000 cP-Sugar Concentration: 85-89° Brix;-Suction: floaded with open tank;-Solid sugar cristals : size 0,3 – 0,9 mm.

NEMO® PUMP FOR MAGMA: OPEN TANK


INSTALLATION DETAILS AT THE SUCTION SIDE



NOT RECOMENDEDNEMO® PUMP FOR MAGMA: OPEN TANK


BEST PRACTICES

The pump must be installed just under the tank;

We should use a net in the bottom of the tank to broken the sugar stones;

We suggest a 30mm net;

The net must be in a position to not generate any restriction to the pump suction, to not block the suction side;

We should have hat water connection to clean the pump and steam connection to clean the pipeline;

Maximum speed recommended 60 RPM;

Pump with inspection ports;

We recommend the installation of sonic (radar) sensor in the suction tank to guaranty at least 0,5 meter of positive pressure.



•Flow rate: up 55 m3/h;•Pressure: from up to 12 bar;•Suction and discharge flange with inspection ports.

NEMO® PUMP FOR SUGAR MASS: CLOSED TANKDETAILS OF INSTALLATION


-If it is possible we suggest to use suction and discharge piping with heated jacket;

-We suggest to have steam conection to clean the pipeline and hot water conection to clean the pump;

-To use the SY pump with a bigger flange connection trying to follow the customer pipeline to avoid restrictions in the suction side;

-Pump with inspection ports;

-Maximum speed recommended 60 RPM;

-The pump must have at least 12 meter of positive pressure.
