CABRERA GOMEZ, Jesús  y  GUANIPA ATACHO, Franklin. Study and proposal of solutions to recurrent failures in horizontal centrifugal pumps. Ingeniería Mecánica [online]. 2010, vol.13, n.2, pp. 32-38. ISSN 1815-5944.

The necessity of making the research outlined in this paper is given by recurrent failures in a set of horizontal centrifugal pumps. These failures interrupt the operating process in an alkylation plant and generate a great negative economic impact because of incrementing maintenance costs and opportunity losses. A study was carried out in order to establish the main causes of repeated failures in the pumping system. As a result, several improvement opportunities of availability of pumps were identified by increasing the useful life of their mechanical seals. Finally, a corrective action program was proposed in order to provide permanent solutions to identified problems.

Palabras clave : maintenance of rotating equipment; recurrent failures; operational reliability; root cause analysis; horizontal centrifugal pumps.
