MORENO-TAMAYO, Ignacio David; CAUSA-MARTILIANO, Enrique; ROSA-ANDINO, Alain Ariel de la  e  AGUILERA-CORRALES, Yordanka. Parameters of Double Suction Centrifuge Pump for the Sugar Industry. Rev Cie Téc Agr [online]. 2018, vol.27, n.2, pp.1-11. ISSN 2071-0054.

The Cuban sugar industry has been working for our designs of centrifugal pumps that date back to the first decades of the last century. As well as other properties and manufacturing under the principles of reverse engineering, using as a standard pumps from prestigious firms such as Ingersoll Rand, Peerless, Worthington among others. Which have presented exploitative problems, causing disruptions in the production process, which are related to the manufacturing process. One reason for this is that the work that aimed to determine the design parameters of a double-suction centrifugal pump for water and sugar sugar juice was carried out in the production facilities of the sugar sector. It describes a methodology for design parameters based on the experience of designers and manufacturers of pumps of international prestige. Within the main results, the value of the specific speed ns = 1 668 stands out, a value that indicates that our design has greater efficiency than the models manufactured and the previous use. The useful power (Nv) and absorb power (Na) with values 32,12 and 45,9 kW, respectively. Lower quantities compared to the useful and absorbent powers of the Allis Chalmers BD 150-83 centrifugal pump. Finally, the proposal became the design parameters for the manufacture of the BCP 125-420 double-suction centrifugal pump, with which it can be passed to the next manufacturing stage
