Abstract:
A method of reducing the amount of pollution emitted by a self priming pump system, comprising the steps of:providing a self priming pump system including a motor, an oil lubricated vacuum pump, and a separator;removing the oil lubricated vacuum pump from the self priming pump system;removing the separator from the self priming pump system;installing a new separator having a reservoir and a inner tank extending through the reservoir;the inner tank defining a passageway which is fluidly isolated from the reservoir and thermally coupled to the reservoir;coupling a liquid ring vacuum pump to the motor of the self priming pump system;connecting a discharge port of the liquid ring vacuum pump to the inner tank of the separator so that the discharge port of the liquid ring vacuum pump is in fluid communication with the passageway of the inner tank; andconnecting an intake of the liquid ring vacuum pump to the reservoir of the separator so that the intake of the liquid ring vacuum pump is in fluid communication with the reservoir of the separator.
