A variable displacement vane pump for dispensing lubricant to a system, the pump comprising: a housing; an inlet for inputting lubricant from a source into the housing; an outlet for delivering pressurized lubricant to the system from the housing; a control slide displaceable within the housing between a first slide position for producing maximum pump displacement and a second slide position for producing a reduced pump displacement to adjust displacement of the pump through the outlet, the second slide position being different than the first slide position; a control chamber, between the housing and the control slide, for receiving pressurized lubricant to move the control slide towards the second position; an electrical valve fluidly connected to the control chamber to control pressure therein; a valve channel connecting the control chamber and the electrical valve; a pressure controlled valve moveable between a first valve position and a second valve position based on an output pressure of the pressurized lubricant delivered through the outlet, the pressure controlled valve being in the first valve position for the output pressure below a threshold level and in the second valve position for the outlet pressure that is at or above the threshold level; a feed channel connecting the pressure controlled valve and the control chamber; a venting channel (72, 78) for venting the electrical valve; a supply channel connecting the pressure controlled valve and the outlet; wherein, in its first valve position, the pressure controlled valve is inactive and (a) closes fluid communication through the feed channel to the control chamber, and (b) opens fluid communication between the electrical valve and a lubricant sump via the venting channel thereby allowing the electrical valve to pressurize the control chamber through the valve channel or to vent the control chamber via the venting channel; wherein, in its second valve position, the pressure controlled valve is active and (a) controls pressure in the control chamber via fluid communication from the outlet, through the supply channel and through the feed channel to the control chamber, and (b) closes fluid communication of the venting channel to the lubricant sump, thereby pressurizing the control chamber via flow from the outlet to the control chamber; and wherein the pressure controlled valve is configured for selective movement to the second valve position via fluid communication through the supply channel when the outlet pressure is at or above the threshold level and the electrical valve is disabled. a housing;
