The selection of a pump model that is not the most appropriate, carts consequences as: excessive consumption of energy, overload in the motor and cavity flow occurrence with consequent decrease in the revenue and in the useful life of the pump.The work extends in the study and evaluation of a diaphragm pump, it marks SHURFLO model 2088, that now has few available data for its knowledge and employment. The measured parameters were: the height (Hm), tension (v) and the current (A), and discharge (Q). The results of the they showed that the maximum values obtained for Hm, revenue (h), potency (Pot), and Q was of 19 mca, 36%, 50 W, and 0,68 m3/h, respectively. The behavior observed in the characteristic curves was exponential, lineal, and polinomial for Hm x Q, Pot x Q, h x Q, respectively.
